1. Before the project is carried out, it is necessary to in -depth coordination with hydropower, wiring, decoration, and lighting. (1) Hydropower engineering: If there is a light design in the KTV room, a set of independent power supply is required for audio. If it is shared with the light, it is easy to generate "power interference"; Anti -interference wiring, or pipeline roads, place the signal line at "in the condition of no interference". Hand -control accessories, MIC joints, and MIC racks need to be in -depth coordination with the decoration project in advance. Pay attention to the structure, durability, and stable equipment. The installation of power amplifier needs to be placed in "the environment that can excrete heat". For a long time and continuous work, the amplifier will generate high temperature. If there is no "moderate space, heat -discharge to the flow environment", the temperature is gradually rising, the power is produced, and the power amplifier will be protected by protection. Function, unscrupulous movement, and continuous high temperature cause the aging of the equipment to accelerate. Therefore, when receiving the case, you need to care about the placing environment of the power amplifier. 4) Lighting engineering: Lighting is often a source of severe interference in the audio. It needs to be caring as follows: Drives with the shared power supply with the light. In the same environment with bad lights, interfere with MIC and bad lights, and also interfere with.
