The connection between the power amplifier and the speaker: We should all know this well, just pay special attention: In terms of signal, the signal line of the power amplifier should be balanced as much as possible, so as to reduce the noise as much as possible. Many sound engineers like to supply one or two signal lines to multiple power amplifiers.
But if it exceeds four power amplifiers, it is still advocated to use signal amplifiers to separate enough signal lines without attenuation to supply each power amplifier for independent use, which can reduce system noise, reduce danger, and improve the signal-to-noise ratio. In terms of power transmission, try to choose thicker and shorter speaker cables and choose reasonable wiring to shorten the spacing of the speaker cables, and one must pay attention to the positive and negative poles to prevent short circuits.
The problem of equipment connection needs to pay attention to: pay attention to the power supply: audio equipment must have a dedicated power supply, which must be separated from the power supply of the lights, and the lights like a lower voltage, but the audio needs to regulate the voltage. With a dedicated power supply, it is also necessary to have a stable and reliable power outlet, and be able to use the "power sequencer" as much as possible, which improves the stability and ease of use despite the increased cost.
All in all: the correct and safe connection of the power supply of all audio equipment is crucial. One more thing to note: Some imported equipment has 110V and 220V selection switches in the power supply. In our country, it must be recognized that it can be connected to the power when the 220V position is selected.
