The tunnel is a professional responsible for the performance of all audio equipment on the performance stage. First of all, all sound sources need to be concentrated to the tuning table, and then divide them into various subsequent roads, marshalies, and adjustment, and then send the general road output audio to the power amplifier and speakers to make sounds so that it can make it with the venue The audio characteristics are compatible. The tunnel needs to know the music characteristics of each link, the frequency of the most easy feedback, and the resonance point of the venue in order to control the volume of each song and make a balanced treatment of them. In addition, it will be improved with the effect.

Human sounds, musical instruments are familiar with the functions and restrictions of each piece of equipment, so that they will not cause distortion and other adverse effects. For the selected equipment to ensure its quality and reliability, prepare for possible faults in advance, and take effective remedy in time. Sometimes the preparations need to be completed a few hours before the performance. Although the time is very tight, for the sake of insurance, each signal line must be taken for yourself to rest assured.

The average output power refers to the power of continuous work for a long time. Peak power refers to the maximum power that is suffered in a short period of time, which is much larger than the rated power. The output of the pourse is determined by the power amplifier. A certain scale of the concert must have a certain power, and the standard is one tile per person. The power will change according to the type of concert, the size of the venue, the reverberation and the number of speakers.
