4. Measurement of sound pressure level. Similarly, connect the pink noise meter to the sound reinforcement system, select several test points to place the sound pressure meter like a debugging equalizer, adjust all the settings of the custom speaker, and finally turn on the system equipment to gradually increase the noise signal volume. Under the premise of ensuring the best dynamics of the signal, adjust the gain of each custom speaker so that the sound pressure of the custom speaker system must meet the design requirements at each test point, and the reference sound pressure level needs to be high, medium, and low. For each frequency band, slightly adjust the equalizer and crossover. Of course, the sound pressure levels of the high, medium, and low frequency bands cannot be exactly the same. Generally, in order to consider the characteristics of the sense of hearing, the sound pressure at high frequencies is required. Make some reductions in the level, and the bass system of the DISCO system requires a higher low-frequency sound pressure level after opening. When testing the sound pressure level, it is necessary to compare the sound pressure level of each test point. If the results of each point have a large deviation, it means that the uniformity of the sound field is not good, and it should be carefully analyzed and improved. The problem will be described later.
5. Debugging of microphones and effects. The debugging of microphones is generally classified. Wired microphones for vocals and musical instruments usually require the cooperation of daily users. When debugging, you need to understand the most reasonable microphone model and operating distance for each person and each instrument. The sound quality is good, and there is no audible. For wireless microphones, you need to pay attention: the location of the antenna should be reasonable, the dead and feedback points of the microphone should be small enough, and the location should be recorded in detail, the signal gain of the receiver should be adequate, and noise suppression The fine-tuning knob should be repeatedly debugged, etc.; the debugging engineering requirements of the effector are not strict, as long as the signal input and output gains are debugged reasonably to ensure a certain margin, and the reverberation time and delay amount are limited to a certain range , So as not to affect the clarity of the language and the continuity of the signal, other specific use adjustments can be made by the operator.
