First, the system introduces the bar area is very large, the sound reinforcement system is divided into three parts, the first part is the dance floor area in front of the DJ station, a total of three brands of medium-range medium-range high-frequency speakers 4 and double 18 inches There are 5 horns, the mid-high frequency speakers are hoisted, and the subwoofers are placed side by side in front of the dance floor. The second part is the sound reinforcement of the scattered area of ​​the hall. There are 8 groups in total. Each group uses one of the same brand three-way long-range medium-high frequency speakers and one 21-inch ultra-low frequency speaker and one double 18-inch low-frequency speaker. The third part is a two-layer sound reinforcement system, using the same brand of dual 15-inch three-way full-range speakers and dual 18-inch low-frequency speakers, two layers of three sides, each side using two sets of full-range and bass combination. The power amplifier part uses the peak and BSS series power amplifiers. A total of four digital audio processors are used. One XTADP226 handles the two-layer 15-inch three-way full-range speaker, and one XTA448 handles the surrounding scattered sound-sounding speakers. The XTADP226 handles the three-way speaker in front of the DJ, and the other ASHLY 4.24 handles all the double 18-inch bass.
Second, the initial feeling <br> Before the adjustment, I heard the sound, the overall sound is fierce, the bass position is relatively high, the overall sound is hard, the feeling of hitting the chest is strong, the middle and high frequency feels not clear enough, the sound is mixed, and the layering is not good. The overall feeling is not comfortable enough. The sounds of the three areas are not synchronized, and the sound in the back field is "running code".
Third, the adjustment steps 1, the first partition adjustment, first adjust the sound reinforcement system in front of the DJ station: first use the SIA software to phase delay correction, the test microphone placed in the dance floor, first measure the transmission time and phase of the subwoofer, and then separately In the test, the transmission time and phase of low frequency, medium high frequency and high frequency are recorded. It is found that the transmission time of several channels is not correct, and the phase of individual channels is not correct. This is the main reason why the medium and high frequency are not clear. After the test, the processor will adjust the transmission time of the four audio channels to be consistent. Then re-opened the audition and found that the sound performance of each frequency band is relatively clear, but the bass position is still high and the sound is hard. Check the bass crossover point to 150 Hz, adjust the crossover point to 99 Hz, and the lower and middle frequency crossover points are also adjusted from 150 Hz to 99 Hz. Listening again, I feel that the low-frequency position drops from the chest to the lower abdomen, but when the sound is loud, there is still a little hard feeling, so the bass is balanced, 125 Hz is attenuated by 8 decibels, and then the sound is appropriate. However, The lower part of the low frequency has a turbid feeling. The lower limit of the low frequency is improved by the processor, the crossover point is increased to 45 Hz, and the attenuation is relatively large at 35 Hz. The bass becomes cleaner, but at this time, the low frequency elasticity and gas are felt. The flu weakened, so the 5 Hz boost was performed at 55 Hz. At this time, the low-frequency elastic force was more suitable, but when the sound was loud, the low-frequency sound was a little "click", so 3 db was applied to 80 Hz. Attenuation, listen again at this time, feel the low-frequency sound is clean, the transient is very good, and at the same time there is the elasticity of the ball, the effect of the bass is basically adjusted.
Because the medium and high frequency speakers are medium and long-range performance speakers, the sound is fierce. Although it feels very cool, but the time is long, people are very tired. First deal with the low-frequency part, the low-frequency part of this speaker is very thick, there is a strong "all-pass" sound, first attenuate 250 Hz, reduce the "all-pass" sound, and then listen, feel the middle frequency has the feeling of hitting the ear, so in The processor attenuates 1250 Hz, and uses a relatively wide Q value, attenuating 4 dB, and the intermediate frequency is quite compliant. The middle and high frequency parts have a strong impact sound, and the metal feel is strong. Using the processor to a wide range of attenuation of 2500 Hz and 5000 Hz, and attenuated by 2 decibels overall, the sound is not so harsh. The high-frequency part of the tooth sound is relatively heavy, a little hairy feeling, the 3K frequency is 3 dB attenuation, the sound is much more comfortable. At this point, the whole release is to listen, I feel that the sound balance of each frequency band is very good. After asking the DJ in the field, they feel that the low frequency is a bit sinking, so the lower limit of the low frequency is lowered to 40 Hz, and the overall feeling is satisfactory.
2. Adjust the speaker in the loose area: The speaker in the loose area is a 5-way system. First determine the crossover points of the five crossovers to be ultra low frequency 35-80, low frequency 50-100, medium low frequency 100-1300, Medium and high frequency 1300-8000, high frequency 8000 or more. As in the previous method, the SIA software is used to correct the phase and delay of each sub-band to ensure that the phase and transmission time of the five bands are consistent. Then the tone is adjusted. Since the speaker and the front speakers use the same unit, the sound processing method is basically the same, but the 21-inch subwoofer is used, so some work has been done on the flu and elastic processing, which has improved 50. Hertz and 63 Hz, attenuated by 80 Hz and 125 Hz. The adjustment amount is 3 decibels. At the same time, the overall ultra-low frequency has been increased by 5 decibels. Because of the long-range loudspeakers used, the amount of high-frequency in the near-field listening is quite sufficient, and the gain of the three channels of the middle and high frequencies is attenuated by 2 decibels, and the overall listening feeling is much more comfortable.
3, adjust the surrounding two-layer sound reinforcement system: first check the double 15-inch three-way full-range sound, it feels a bit strange, then open the processor to check the crossover point, found that the crossover point setting is not correct, the crossover point of this speaker It is 300/3500 Hz, but it is set to 120/1800 Hz. After resetting, the sound returns to normal. Then, the phase correction is performed, and after the phase and the delay are corrected, the sound tone is adjusted. Due to the double 15-inch structure, the low-frequency part is thicker, and the impact on the head and chest is strong at high volume. Therefore, the attenuation is 3 dB for 125 Hz and 250 Hz, and the middle part is wide for 1250 Hz. Attenuation. The treble portion is attenuated by 4 decibels at 5000 Hz and 8000 Hz. The overall listening feels more comfortable, and the tone adjustment of the subwoofer is the same as the bass adjustment of the DJ section. However, the number of bass on the second floor is relatively small, and the overall improvement of the subwoofer is 3 decibels.
4. Three areas for overall coordination and debugging: The above three steps independently debug the speakers in the three areas. Because the three areas are different in position, when the three areas are all sounding, due to the different transmission time, There is an unsynchronized “running code†phenomenon in the back field. Therefore, the SIA software is used to delay the sound reinforcement system in the three areas. First, the sound reinforcement system in the loose area and the sound reinforcement system in the DJ area are synchronized. Place the test microphone in the loose area, detect the sound propagation time of the DJ station sound reinforcement system to reach this area, turn off the DJ stage speaker, and measure the transmission time of the speaker in the loose area to reach this position, and then adjust the speaker area of ​​the loose area. The input channel delay of the device allows the sounds of the speakers in these two areas to be synchronized. After the adjustment is completed, the second layer speaker and the main amplifier box are synchronously adjusted. After the adjustment, the audition is performed again, and the running code phenomenon is gone. The overall field sound consistency is very good.
5, DJ take turns playing the disc for overall evaluation: three DJs take turns playing different music styles, making the necessary fine-tuning of the system. The DJ brothers responded that the bass was a bit soft and the power was a little weak, so the 125 Hz of the bass was properly upgraded on the processor, and the sense of strength was strengthened. At this time, because it is an empty field, the reflection in the field is relatively heavy, and the low-frequency part is slightly mixed, so it is not used.
6, DJ monitoring adjustment, DJ station used a NEXOPS15 as DJ monitor, because there is no PS15TD controller, the sound is relatively sturdy, and relatively thin, with an equalizer, according to the PS15TD controller's equalization compensation parameters The setting, feels a lot more comfortable, and at the same time properly raised a little intermediate frequency 1600 Hz, so that the sound of the PS15 and the sound of the field are relatively close.
7. When the night is full, the overall feeling is good, but because the guest is full, the low-frequency feeling is a little lacking, so the gain of the low-frequency channel is increased by 2 decibels on the processor, and the low-frequency sense is much better. The overall feeling is high-frequency clear, low-frequency has toughness, the overall sense of envelopment and sense of touch is strong, the ears have no pressure, and you can chat with normal volume in the field. At this time, when the input and output signals of the mixer are 0 decibels, all the amplifiers work in the state of -6 decibels, and the system has a large margin, and the system safety factor is relatively high. The adjusted parameters are saved, and all the processors are locked by the in-game voice control brothers, and the adjustment work ends, and the accumulated time is four hours. First, the system introduces the bar area is very large, the sound reinforcement system is divided into three parts, the first part is the dance floor area in front of the DJ station, a total of three brands of medium-range medium-range high-frequency speakers 4 and double 18 inches There are 5 horns, the mid-high frequency speakers are hoisted, and the subwoofers are placed side by side in front of the dance floor. The second part is the sound reinforcement of the scattered area of ​​the hall. There are 8 groups in total. Each group uses one of the same brand three-way long-range medium-high frequency speakers and one 21-inch ultra-low frequency speaker and one double 18-inch low-frequency speaker. The third part is a two-layer sound reinforcement system, using the same brand of dual 15-inch three-way full-range speakers and dual 18-inch low-frequency speakers, two layers of three sides, each side using two sets of full-range and bass combination. The power amplifier part uses the peak and BSS series power amplifiers. A total of four digital audio processors are used. One XTADP226 handles the two-layer 15-inch three-way full-range speaker, and one XTA448 handles the surrounding scattered sound-sounding speakers. The XTADP226 handles the three-way speaker in front of the DJ, and the other ASHLY 4.24 handles all the double 18-inch bass.
Second, the initial feeling <br> Before the adjustment, I heard the sound, the overall sound is fierce, the bass position is relatively high, the overall sound is hard, the feeling of hitting the chest is strong, the middle and high frequency feels not clear enough, the sound is mixed, and the layering is not good. The overall feeling is not comfortable enough. The sounds of the three areas are not synchronized, and the sound in the back field is "running code".

Then re-opened the audition and found that the sound performance of each frequency band is relatively clear, but the bass position is still high and the sound is hard. Check the bass crossover point to 150 Hz, adjust the crossover point to 99 Hz, and the lower and middle frequency crossover points are also adjusted from 150 Hz to 99 Hz. Listening again, I feel that the low-frequency position drops from the chest to the lower abdomen, but when the sound is loud, there is still a little hard feeling, so the bass is balanced, 125 Hz is attenuated by 8 decibels, and then the sound is appropriate. However, The lower part of the low frequency has a turbid feeling. The lower limit of the low frequency is improved by the processor, the crossover point is increased to 45 Hz, and the attenuation is relatively large at 35 Hz. The bass becomes cleaner, but at this time, the low frequency elasticity and gas are felt. The flu weakened, so the 5 Hz boost was performed at 55 Hz. At this time, the low-frequency elastic force was more suitable, but when the sound was loud, the low-frequency sound was a little "click", so 3 db was applied to 80 Hz. Attenuation, listen again at this time, feel the low-frequency sound is clean, the transient is very good, and at the same time there is the elasticity of the ball, the effect of the bass is basically adjusted.
Because the medium and high frequency speakers are medium and long-range performance speakers, the sound is fierce. Although it feels very cool, but the time is long, people are very tired.

The high-frequency part of the tooth sound is relatively heavy, a little hairy feeling, the 3K frequency is 3 dB attenuation, the sound is much more comfortable. At this point, the whole release is to listen, I feel that the sound balance of each frequency band is very good. After asking the DJ in the field, they feel that the low frequency is a bit sinking, so the lower limit of the low frequency is lowered to 40 Hz, and the overall feeling is satisfactory.
2. Adjust the speaker in the loose area: The speaker in the loose area is a 5-way system. First determine the crossover points of the five crossovers to be ultra low frequency 35-80, low frequency 50-100, medium low frequency 100-1300, Medium and high frequency 1300-8000, high frequency 8000 or more. As in the previous method, the SIA software is used to correct the phase and delay of each sub-band to ensure that the phase and transmission time of the five bands are consistent. Then the tone is adjusted. Since the speaker and the front speakers use the same unit, the sound processing method is basically the same, but the 21-inch subwoofer is used, so some work has been done on the flu and elastic processing, which has improved 50. Hertz and 63 Hz, attenuated by 80 Hz and 125 Hz. The adjustment amount is 3 decibels. At the same time, the overall ultra-low frequency has been increased by 5 decibels. Because of the long-range loudspeakers used, the amount of high-frequency in the near-field listening is quite sufficient, and the gain of the three channels of the middle and high frequencies is attenuated by 2 decibels, and the overall listening feeling is much more comfortable.
3, adjust the surrounding two-layer sound reinforcement system: first check the double 15-inch three-way full-range sound, it feels a bit strange, then open the processor to check the crossover point, found that the crossover point setting is not correct, the crossover point of this speaker It is 300/3500 Hz, but it is set to 120/1800 Hz. After resetting, the sound returns to normal. Then, the phase correction is performed, and after the phase and the delay are corrected, the sound tone is adjusted. Due to the double 15-inch structure, the low-frequency part is thicker, and the impact on the head and chest is strong at high volume. Therefore, the attenuation is 3 dB for 125 Hz and 250 Hz, and the middle part is wide for 1250 Hz. Attenuation. The treble portion is attenuated by 4 decibels at 5000 Hz and 8000 Hz. The overall listening feels more comfortable, and the tone adjustment of the subwoofer is the same as the bass adjustment of the DJ section. However, the number of bass on the second floor is relatively small, and the overall improvement of the subwoofer is 3 decibels.
4. Three areas for overall coordination and debugging: The above three steps independently debug the speakers in the three areas. Because the three areas are different in position, when the three areas are all sounding, due to the different transmission time, There is an unsynchronized “running code†phenomenon in the back field.

The input channel delay of the device allows the sounds of the speakers in these two areas to be synchronized. After the adjustment is completed, the second layer speaker and the main amplifier box are synchronously adjusted. After the adjustment, the audition is performed again, and the running code phenomenon is gone. The overall field sound consistency is very good.
5, DJ take turns playing the disc for overall evaluation: three DJs take turns playing different music styles, making the necessary fine-tuning of the system.

The XTADP226 handles the three-way speaker in front of the DJ, and the other ASHLY 4.24 handles all the double 18-inch bass.
Second, the initial feeling <br> Before the adjustment, I heard the sound, the overall sound is fierce, the bass position is relatively high, the overall sound is hard, the feeling of hitting the chest is strong, the middle and high frequency feels not clear enough, the sound is mixed, and the layering is not good. The overall feeling is not comfortable enough. The sounds of the three areas are not synchronized, and the sound in the back field is "running code".
Third, the adjustment steps 1, the first partition adjustment, first adjust the sound reinforcement system in front of the DJ station: first use the SIA software to phase delay correction, the test microphone placed in the dance floor, first measure the transmission time and phase of the subwoofer, and then separately In the test, the transmission time and phase of low frequency, medium high frequency and high frequency are recorded.

Then re-opened the audition and found that the sound performance of each frequency band is relatively clear, but the bass position is still high and the sound is hard. Check the bass crossover point to 150 Hz, adjust the crossover point to 99 Hz, and the lower and middle frequency crossover points are also adjusted from 150 Hz to 99 Hz. Listening again, I feel that the low-frequency position drops from the chest to the lower abdomen, but when the sound is loud, there is still a little hard feeling, so the bass is balanced, 125 Hz is attenuated by 8 decibels, and then the sound is appropriate. However, The lower part of the low frequency has a turbid feeling. The lower limit of the low frequency is improved by the processor, the crossover point is increased to 45 Hz, and the attenuation is relatively large at 35 Hz.

The middle and high frequency parts have a strong impact sound, and the metal feel is strong. Using the processor to a wide range of attenuation of 2500 Hz and 5000 Hz, and attenuated by 2 decibels overall, the sound is not so harsh. The high-frequency part of the tooth sound is relatively heavy, a little hairy feeling, the 3K frequency is 3 dB attenuation, the sound is much more comfortable. At this point, the whole release is to listen, I feel that the sound balance of each frequency band is very good. After asking the DJ in the field, they feel that the low frequency is a bit sinking, so the lower limit of the low frequency is lowered to 40 Hz, and the overall feeling is satisfactory.
2. Adjust the speaker in the loose area: The speaker in the loose area is a 5-way system. First determine the crossover points of the five crossovers to be ultra low frequency 35-80, low frequency 50-100, medium low frequency 100-1300, Medium and high frequency 1300-8000, high frequency 8000 or more. As in the previous method, the SIA software is used to correct the phase and delay of each sub-band to ensure that the phase and transmission time of the five bands are consistent. Then the tone is adjusted. Since the speaker and the front speakers use the same unit, the sound processing method is basically the same, but the 21-inch subwoofer is used, so some work has been done on the flu and elastic processing, which has improved 50. Hertz and 63 Hz, attenuated by 80 Hz and 125 Hz. The adjustment amount is 3 decibels. At the same time, the overall ultra-low frequency has been increased by 5 decibels. Because of the long-range loudspeakers used, the amount of high-frequency in the near-field listening is quite sufficient, and the gain of the three channels of the middle and high frequencies is attenuated by 2 decibels, and the overall listening feeling is much more comfortable.
3, adjust the surrounding two-layer sound reinforcement system: first check the double 15-inch three-way full-range sound, it feels a bit strange, then open the processor to check the crossover point, found that the crossover point setting is not correct, the crossover point of this speaker It is 300/3500 Hz, but it is set to 120/1800 Hz. After resetting, the sound returns to normal. Then, the phase correction is performed, and after the phase and the delay are corrected, the sound tone is adjusted. Due to the double 15-inch structure, the low-frequency part is thicker, and the impact on the head and chest is strong at high volume. Therefore, the attenuation is 3 dB for 125 Hz and 250 Hz, and the middle part is wide for 1250 Hz. Attenuation. The treble portion is attenuated by 4 decibels at 5000 Hz and 8000 Hz. The overall listening feels more comfortable, and the tone adjustment of the subwoofer is the same as the bass adjustment of the DJ section. However, the number of bass on the second floor is relatively small, and the overall improvement of the subwoofer is 3 decibels.
4. Three areas for overall coordination and debugging: The above three steps independently debug the speakers in the three areas. Because the three areas are different in position, when the three areas are all sounding, due to the different transmission time, There is an unsynchronized “running code†phenomenon in the back field. Therefore, the SIA software is used to delay the sound reinforcement system in the three areas. First, the sound reinforcement system in the loose area and the sound reinforcement system in the DJ area are synchronized. Place the test microphone in the loose area, detect the sound propagation time of the DJ station sound reinforcement system to reach this area, turn off the DJ stage speaker, and measure the transmission time of the speaker in the loose area to reach this position, and then adjust the speaker area of ​​the loose area. The input channel delay of the device allows the sounds of the speakers in these two areas to be synchronized. After the adjustment is completed, the second layer speaker and the main amplifier box are synchronously adjusted. After the adjustment, the audition is performed again, and the running code phenomenon is gone. The overall field sound consistency is very good.
5, DJ take turns playing the disc for overall evaluation: three DJs take turns playing different music styles, making the necessary fine-tuning of the system. The DJ brothers responded that the bass was a bit soft and the power was a little weak, so the 125 Hz of the bass was properly upgraded on the processor, and the sense of strength was strengthened. At this time, because it is an empty field, the reflection in the field is relatively heavy, and the low-frequency part is slightly mixed, so it is not used.
6, DJ monitoring adjustment, DJ station used a NEXOPS15 as DJ monitor, because there is no PS15TD controller, the sound is relatively sturdy, and relatively thin, with an equalizer, according to the PS15TD controller's equalization compensation parameters The setting, feels a lot more comfortable, and at the same time properly raised a little intermediate frequency 1600 Hz, so that the sound of the PS15 and the sound of the field are relatively close.
7. When the night is full, the overall feeling is good, but because the guest is full, the low-frequency feeling is a little lacking, so the gain of the low-frequency channel is increased by 2 decibels on the processor, and the low-frequency sense is much better. The overall feeling is high-frequency clear, low-frequency has toughness, the overall sense of envelopment and sense of touch is strong, the ears have no pressure, and you can chat with normal volume in the field. At this time, when the input and output signals of the mixer are 0 decibels, all the amplifiers work in the state of -6 decibels, and the system has a large margin, and the system safety factor is relatively high. The adjusted parameters are saved, and all the processors are locked by the in-game voice control brothers, and the adjustment work ends, and the accumulated time is four hours.
Second, the initial feeling <br> Before the adjustment, I heard the sound, the overall sound is fierce, the bass position is relatively high, the overall sound is hard, the feeling of hitting the chest is strong, the middle and high frequency feels not clear enough, the sound is mixed, and the layering is not good. The overall feeling is not comfortable enough. The sounds of the three areas are not synchronized, and the sound in the back field is "running code".
Third, the adjustment steps 1, the first partition adjustment, first adjust the sound reinforcement system in front of the DJ station: first use the SIA software to phase delay correction, the test microphone placed in the dance floor, first measure the transmission time and phase of the subwoofer, and then separately In the test, the transmission time and phase of low frequency, medium high frequency and high frequency are recorded. It is found that the transmission time of several channels is not correct, and the phase of individual channels is not correct. This is the main reason why the medium and high frequency are not clear. After the test, the processor will adjust the transmission time of the four audio channels to be consistent. Then re-opened the audition and found that the sound performance of each frequency band is relatively clear, but the bass position is still high and the sound is hard. Check the bass crossover point to 150 Hz, adjust the crossover point to 99 Hz, and the lower and middle frequency crossover points are also adjusted from 150 Hz to 99 Hz. Listening again, I feel that the low-frequency position drops from the chest to the lower abdomen, but when the sound is loud, there is still a little hard feeling, so the bass is balanced, 125 Hz is attenuated by 8 decibels, and then the sound is appropriate. However, The lower part of the low frequency has a turbid feeling. The lower limit of the low frequency is improved by the processor, the crossover point is increased to 45 Hz, and the attenuation is relatively large at 35 Hz. The bass becomes cleaner, but at this time, the low frequency elasticity and gas are felt. The flu weakened, so the 5 Hz boost was performed at 55 Hz. At this time, the low-frequency elastic force was more suitable, but when the sound was loud, the low-frequency sound was a little "click", so 3 db was applied to 80 Hz. Attenuation, listen again at this time, feel the low-frequency sound is clean, the transient is very good, and at the same time there is the elasticity of the ball, the effect of the bass is basically adjusted.
Because the medium and high frequency speakers are medium and long-range performance speakers, the sound is fierce. Although it feels very cool, but the time is long, people are very tired. First deal with the low-frequency part, the low-frequency part of this speaker is very thick, there is a strong "all-pass" sound, first attenuate 250 Hz, reduce the "all-pass" sound, and then listen, feel the middle frequency has the feeling of hitting the ear, so in The processor attenuates 1250 Hz, and uses a relatively wide Q value, attenuating 4 dB, and the intermediate frequency is quite compliant. The middle and high frequency parts have a strong impact sound, and the metal feel is strong. Using the processor to a wide range of attenuation of 2500 Hz and 5000 Hz, and attenuated by 2 decibels overall, the sound is not so harsh. The high-frequency part of the tooth sound is relatively heavy, a little hairy feeling, the 3K frequency is 3 dB attenuation, the sound is much more comfortable. At this point, the whole release is to listen, I feel that the sound balance of each frequency band is very good. After asking the DJ in the field, they feel that the low frequency is a bit sinking, so the lower limit of the low frequency is lowered to 40 Hz, and the overall feeling is satisfactory.
2. Adjust the speaker in the loose area: The speaker in the loose area is a 5-way system. First determine the crossover points of the five crossovers to be ultra low frequency 35-80, low frequency 50-100, medium low frequency 100-1300, Medium and high frequency 1300-8000, high frequency 8000 or more. As in the previous method, the SIA software is used to correct the phase and delay of each sub-band to ensure that the phase and transmission time of the five bands are consistent. Then the tone is adjusted. Since the speaker and the front speakers use the same unit, the sound processing method is basically the same, but the 21-inch subwoofer is used, so some work has been done on the flu and elastic processing, which has improved 50. Hertz and 63 Hz, attenuated by 80 Hz and 125 Hz. The adjustment amount is 3 decibels. At the same time, the overall ultra-low frequency has been increased by 5 decibels. Because of the long-range loudspeakers used, the amount of high-frequency in the near-field listening is quite sufficient, and the gain of the three channels of the middle and high frequencies is attenuated by 2 decibels, and the overall listening feeling is much more comfortable.
3, adjust the surrounding two-layer sound reinforcement system: first check the double 15-inch three-way full-range sound, it feels a bit strange, then open the processor to check the crossover point, found that the crossover point setting is not correct, the crossover point of this speaker It is 300/3500 Hz, but it is set to 120/1800 Hz. After resetting, the sound returns to normal. Then, the phase correction is performed, and after the phase and the delay are corrected, the sound tone is adjusted. Due to the double 15-inch structure, the low-frequency part is thicker, and the impact on the head and chest is strong at high volume. Therefore, the attenuation is 3 dB for 125 Hz and 250 Hz, and the middle part is wide for 1250 Hz. Attenuation. The treble portion is attenuated by 4 decibels at 5000 Hz and 8000 Hz. The overall listening feels more comfortable, and the tone adjustment of the subwoofer is the same as the bass adjustment of the DJ section. However, the number of bass on the second floor is relatively small, and the overall improvement of the subwoofer is 3 decibels.
4. Three areas for overall coordination and debugging: The above three steps independently debug the speakers in the three areas. Because the three areas are different in position, when the three areas are all sounding, due to the different transmission time, There is an unsynchronized “running code†phenomenon in the back field. Therefore, the SIA software is used to delay the sound reinforcement system in the three areas. First, the sound reinforcement system in the loose area and the sound reinforcement system in the DJ area are synchronized. Place the test microphone in the loose area, detect the sound propagation time of the DJ station sound reinforcement system to reach this area, turn off the DJ stage speaker, and measure the transmission time of the speaker in the loose area to reach this position, and then adjust the speaker area of ​​the loose area. The input channel delay of the device allows the sounds of the speakers in these two areas to be synchronized. After the adjustment is completed, the second layer speaker and the main amplifier box are synchronously adjusted. After the adjustment, the audition is performed again, and the running code phenomenon is gone. The overall field sound consistency is very good.
5, DJ take turns playing the disc for overall evaluation: three DJs take turns playing different music styles, making the necessary fine-tuning of the system. The DJ brothers responded that the bass was a bit soft and the power was a little weak, so the 125 Hz of the bass was properly upgraded on the processor, and the sense of strength was strengthened. At this time, because it is an empty field, the reflection in the field is relatively heavy, and the low-frequency part is slightly mixed, so it is not used.
6, DJ monitoring adjustment, DJ station used a NEXOPS15 as DJ monitor, because there is no PS15TD controller, the sound is relatively sturdy, and relatively thin, with an equalizer, according to the PS15TD controller's equalization compensation parameters The setting, feels a lot more comfortable, and at the same time properly raised a little intermediate frequency 1600 Hz, so that the sound of the PS15 and the sound of the field are relatively close.
7. When the night is full, the overall feeling is good, but because the guest is full, the low-frequency feeling is a little lacking, so the gain of the low-frequency channel is increased by 2 decibels on the processor, and the low-frequency sense is much better. The overall feeling is high-frequency clear, low-frequency has toughness, the overall sense of envelopment and sense of touch is strong, the ears have no pressure, and you can chat with normal volume in the field. At this time, when the input and output signals of the mixer are 0 decibels, all the amplifiers work in the state of -6 decibels, and the system has a large margin, and the system safety factor is relatively high. The adjusted parameters are saved, and all the processors are locked by the in-game voice control brothers, and the adjustment work ends, and the accumulated time is four hours. First, the system introduces the bar area is very large, the sound reinforcement system is divided into three parts, the first part is the dance floor area in front of the DJ station, a total of three brands of medium-range medium-range high-frequency speakers 4 and double 18 inches There are 5 horns, the mid-high frequency speakers are hoisted, and the subwoofers are placed side by side in front of the dance floor. The second part is the sound reinforcement of the scattered area of ​​the hall. There are 8 groups in total. Each group uses one of the same brand three-way long-range medium-high frequency speakers and one 21-inch ultra-low frequency speaker and one double 18-inch low-frequency speaker. The third part is a two-layer sound reinforcement system, using the same brand of dual 15-inch three-way full-range speakers and dual 18-inch low-frequency speakers, two layers of three sides, each side using two sets of full-range and bass combination. The power amplifier part uses the peak and BSS series power amplifiers. A total of four digital audio processors are used. One XTADP226 handles the two-layer 15-inch three-way full-range speaker, and one XTA448 handles the surrounding scattered sound-sounding speakers. The XTADP226 handles the three-way speaker in front of the DJ, and the other ASHLY 4.24 handles all the double 18-inch bass.
Second, the initial feeling <br> Before the adjustment, I heard the sound, the overall sound is fierce, the bass position is relatively high, the overall sound is hard, the feeling of hitting the chest is strong, the middle and high frequency feels not clear enough, the sound is mixed, and the layering is not good. The overall feeling is not comfortable enough. The sounds of the three areas are not synchronized, and the sound in the back field is "running code".
Third, the adjustment steps 1, the first partition adjustment, first adjust the sound reinforcement system in front of the DJ station: first use the SIA software to phase delay correction, the test microphone placed in the dance floor, first measure the transmission time and phase of the subwoofer, and then separately In the test, the transmission time and phase of low frequency, medium high frequency and high frequency are recorded. It is found that the transmission time of several channels is not correct, and the phase of individual channels is not correct. This is the main reason why the medium and high frequency are not clear. After the test, the processor will adjust the transmission time of the four audio channels to be consistent. Then re-opened the audition and found that the sound performance of each frequency band is relatively clear, but the bass position is still high and the sound is hard. Check the bass crossover point to 150 Hz, adjust the crossover point to 99 Hz, and the lower and middle frequency crossover points are also adjusted from 150 Hz to 99 Hz. Listening again, I feel that the low-frequency position drops from the chest to the lower abdomen, but when the sound is loud, there is still a little hard feeling, so the bass is balanced, 125 Hz is attenuated by 8 decibels, and then the sound is appropriate. However, The lower part of the low frequency has a turbid feeling. The lower limit of the low frequency is improved by the processor, the crossover point is increased to 45 Hz, and the attenuation is relatively large at 35 Hz. The bass becomes cleaner, but at this time, the low frequency elasticity and gas are felt. The flu weakened, so the 5 Hz boost was performed at 55 Hz. At this time, the low-frequency elastic force was more suitable, but when the sound was loud, the low-frequency sound was a little "click", so 3 db was applied to 80 Hz. Attenuation, listen again at this time, feel the low-frequency sound is clean, the transient is very good, and at the same time there is the elasticity of the ball, the effect of the bass is basically adjusted.
Because the medium and high frequency speakers are medium and long-range performance speakers, the sound is fierce. Although it feels very cool, but the time is long, people are very tired. First deal with the low-frequency part, the low-frequency part of this speaker is very thick, there is a strong "all-pass" sound, first attenuate 250 Hz, reduce the "all-pass" sound, and then listen, feel the middle frequency has the feeling of hitting the ear, so in The processor attenuates 1250 Hz, and uses a relatively wide Q value, attenuating 4 dB, and the intermediate frequency is quite compliant. The middle and high frequency parts have a strong impact sound, and the metal feel is strong. Using the processor to a wide range of attenuation of 2500 Hz and 5000 Hz, and attenuated by 2 decibels overall, the sound is not so harsh. The high-frequency part of the tooth sound is relatively heavy, a little hairy feeling, the 3K frequency is 3 dB attenuation, the sound is much more comfortable. At this point, the whole release is to listen, I feel that the sound balance of each frequency band is very good. After asking the DJ in the field, they feel that the low frequency is a bit sinking, so the lower limit of the low frequency is lowered to 40 Hz, and the overall feeling is satisfactory.
2. Adjust the speaker in the loose area: The speaker in the loose area is a 5-way system. First determine the crossover points of the five crossovers to be ultra low frequency 35-80, low frequency 50-100, medium low frequency 100-1300, Medium and high frequency 1300-8000, high frequency 8000 or more. As in the previous method, the SIA software is used to correct the phase and delay of each sub-band to ensure that the phase and transmission time of the five bands are consistent. Then the tone is adjusted. Since the speaker and the front speakers use the same unit, the sound processing method is basically the same, but the 21-inch subwoofer is used, so some work has been done on the flu and elastic processing, which has improved 50. Hertz and 63 Hz, attenuated by 80 Hz and 125 Hz. The adjustment amount is 3 decibels. At the same time, the overall ultra-low frequency has been increased by 5 decibels. Because of the long-range loudspeakers used, the amount of high-frequency in the near-field listening is quite sufficient, and the gain of the three channels of the middle and high frequencies is attenuated by 2 decibels, and the overall listening feeling is much more comfortable.
3, adjust the surrounding two-layer sound reinforcement system: first check the double 15-inch three-way full-range sound, it feels a bit strange, then open the processor to check the crossover point, found that the crossover point setting is not correct, the crossover point of this speaker It is 300/3500 Hz, but it is set to 120/1800 Hz. After resetting, the sound returns to normal. Then, the phase correction is performed, and after the phase and the delay are corrected, the sound tone is adjusted. Due to the double 15-inch structure, the low-frequency part is thicker, and the impact on the head and chest is strong at high volume. Therefore, the attenuation is 3 dB for 125 Hz and 250 Hz, and the middle part is wide for 1250 Hz. Attenuation. The treble portion is attenuated by 4 decibels at 5000 Hz and 8000 Hz. The overall listening feels more comfortable, and the tone adjustment of the subwoofer is the same as the bass adjustment of the DJ section. However, the number of bass on the second floor is relatively small, and the overall improvement of the subwoofer is 3 decibels.
4. Three areas for overall coordination and debugging: The above three steps independently debug the speakers in the three areas.

The input channel delay of the device allows the sounds of the speakers in these two areas to be synchronized. After the adjustment is completed, the second layer speaker and the main amplifier box are synchronously adjusted. After the adjustment, the audition is performed again, and the running code phenomenon is gone. The overall field sound consistency is very good.
5, DJ take turns playing the disc for overall evaluation: three DJs take turns playing different music styles, making the necessary fine-tuning of the system.

Check the bass crossover point to 150 Hz, adjust the crossover point to 99 Hz, and the lower and middle frequency crossover points are also adjusted from 150 Hz to 99 Hz. Listening again, I feel that the low-frequency position drops from the chest to the lower abdomen, but when the sound is loud, there is still a little hard feeling, so the bass is balanced, 125 Hz is attenuated by 8 decibels, and then the sound is appropriate. However, The lower part of the low frequency has a turbid feeling. The lower limit of the low frequency is improved by the processor, the crossover point is increased to 45 Hz, and the attenuation is relatively large at 35 Hz. The bass becomes cleaner, but at this time, the low frequency elasticity and gas are felt. The flu weakened, so the 5 Hz boost was performed at 55 Hz. At this time, the low-frequency elastic force was more suitable, but when the sound was loud, the low-frequency sound was a little "click", so 3 db was applied to 80 Hz.

2. Adjust the speaker in the loose area: The speaker in the loose area is a 5-way system. First determine the crossover points of the five crossovers to be ultra low frequency 35-80, low frequency 50-100, medium low frequency 100-1300, Medium and high frequency 1300-8000, high frequency 8000 or more. As in the previous method, the SIA software is used to correct the phase and delay of each sub-band to ensure that the phase and transmission time of the five bands are consistent. Then the tone is adjusted. Since the speaker and the front speakers use the same unit, the sound processing method is basically the same, but the 21-inch subwoofer is used, so some work has been done on the flu and elastic processing, which has improved 50. Hertz and 63 Hz, attenuated by 80 Hz and 125 Hz. The adjustment amount is 3 decibels. At the same time, the overall ultra-low frequency has been increased by 5 decibels. Because of the long-range loudspeakers used, the amount of high-frequency in the near-field listening is quite sufficient, and the gain of the three channels of the middle and high frequencies is attenuated by 2 decibels, and the overall listening feeling is much more comfortable.
3, adjust the surrounding two-layer sound reinforcement system: first check the double 15-inch three-way full-range sound, it feels a bit strange, then open the processor to check the crossover point, found that the crossover point setting is not correct, the crossover point of this speaker It is 300/3500 Hz, but it is set to 120/1800 Hz. After resetting, the sound returns to normal. Then, the phase correction is performed, and after the phase and the delay are corrected, the sound tone is adjusted. Due to the double 15-inch structure, the low-frequency part is thicker, and the impact on the head and chest is strong at high volume. Therefore, the attenuation is 3 dB for 125 Hz and 250 Hz, and the middle part is wide for 1250 Hz. Attenuation. The treble portion is attenuated by 4 decibels at 5000 Hz and 8000 Hz. The overall listening feels more comfortable, and the tone adjustment of the subwoofer is the same as the bass adjustment of the DJ section. However, the number of bass on the second floor is relatively small, and the overall improvement of the subwoofer is 3 decibels.
4. Three areas for overall coordination and debugging: The above three steps independently debug the speakers in the three areas. Because the three areas are different in position, when the three areas are all sounding, due to the different transmission time, There is an unsynchronized “running code†phenomenon in the back field.

Place the test microphone in the loose area, detect the sound propagation time of the DJ station sound reinforcement system to reach this area, turn off the DJ stage speaker, and measure the transmission time of the speaker in the loose area to reach this position, and then adjust the speaker area of ​​the loose area. The input channel delay of the device allows the sounds of the speakers in these two areas to be synchronized. After the adjustment is completed, the second layer speaker and the main amplifier box are synchronously adjusted. After the adjustment, the audition is performed again, and the running code phenomenon is gone. The overall field sound consistency is very good.
5, DJ take turns playing the disc for overall evaluation: three DJs take turns playing different music styles, making the necessary fine-tuning of the system. The DJ brothers responded that the bass was a bit soft and the power was a little weak, so the 125 Hz of the bass was properly upgraded on the processor, and the sense of strength was strengthened.

7. When the night is full, the overall feeling is good, but because the guest is full, the low-frequency feeling is a little lacking, so the gain of the low-frequency channel is increased by 2 decibels on the processor, and the low-frequency sense is much better. The overall feeling is high-frequency clear, low-frequency has toughness, the overall sense of envelopment and sense of touch is strong, the ears have no pressure, and you can chat with normal volume in the field. At this time, when the input and output signals of the mixer are 0 decibels, all the amplifiers work in the state of -6 decibels, and the system has a large margin, and the system safety factor is relatively high. The adjusted parameters are saved, and all the processors are locked by the in-game voice control brothers, and the adjustment work ends, and the accumulated time is four hours.
