The join of result put and sound box: this we should understand very well, want extra attention only: The signal line that result puts in signal respect should use balanced line as far as possible, can reduce noise as far as possible so. A lot of sound division likes to supply many power amplifier with one or two signal lines.

But if exceed 4 when work is put, still be advocate to use signal amplifier to divide a quantity enough many, the signal line that did not attenuate supplies every work is put alone use, can reduce system noise, reduce danger, progress signal noise ratio so. In power transmission respect, choose as far as possible thick, short sound box line and choose reasonable wiring to shorten the interval of sound box line, again must pay attention to positive and negative, prevent short circuit

Equipment connection needs to pay attention to the problem: pay attention to the power supply: audio equipment should have a special power supply, to be separated from the power supply of lights, and lights like a lower voltage, but audio should be standardized voltage. With a special power supply, there should be a stable and reliable power socket, which can try to use the "power timing device ", although the cost is added, it improves the stability and ease of use.

After all: correct, safe connection of all sound equipment power is crucial. There is also a point to note: some imported equipment power parts will have 110V and 220V selection switches, in our country, must be admitted that selection in the 220V bearing can connect to electricity.
