The debugging of audio engineering is generally divided into system debug and sound debug, the following are the common steps of the system:
1, according to the relevant drawings and good related equipment, and make the line inspection, carefully check the correctness of the line connection joints, confirmed no problem.
2, set the initial state of the equipment, the amplifier input is set to a minimum, all peripheral equipment input and output knob settings to 0 dB location, electricity was observed in all of the equipment can be normal energized display, then all the equipment volume is set to a quarter to the middle position, the volume is not more than half of its maximum volume.
3, the initial trial state operating system: a CD or DVD playback source into a familiar music. This is when the music sounded both know is their playing, and can recognize the voice is normal, when heard the voice came, the proper power amplifier gain control, measuring amplifier output normal level, adjust the mixer input level to the normal position.
4, the sound of running normally, the adjustment to the sound, the sound system is composed of a plurality of devices, these devices tend to have more features, the sound effect processing, so the final out of the voice, OK, one is depends on the quality of equipment and more important debugging. According to the experience and the related test index, the tuning bench, equalizer, effect device and other equipment for the corresponding parameters debugging, setting. And record the record.
5, dynamic sound field debugging: general dynamic adjusting equipment refers to when playing music try to simulate the stage performances, the sound, echo, is called Xiao, heavy bass effect systematically and fine adjustment, especially the dynamic effects of sound field adjusting is very professional skills to complete the need for.
