Product Description
Name: 1400W switch power suplly amplifier

Product Feature:
1. Adopting SMT technology. It looks on top grade, also high integration and stable performance.
2. Switching power supply technology is used in power supply to lower the power consumption. It is less weight and convenient for touring performance.
3. Cannon and terminal block output to make machine more stability.
4. The machine has a 30Hz low cut choice on-off and a channel choice on-off.
5. It has stereo, bright and merge output, Easy operation of function bill in the back side.
6. There is a independent protection, clip, signal instruction, so it can monitor the working status of each channel easily.
7. The protection function is very perfect, . It has over-temperature protection, current protection, short circuit protection, to ensure that the machine can not damaged in harsh environments or under wrong operation situation.
8. The cooling system using a continuously variable low-noise large displacement blower, to ensure the machine operates at a suitable low operating temperature.
9. Built in intelligent limiter system, It can detect output signal is distortion or not. When the distortion is more than 0.5%, the machine will turn into a limiter circuit situation,
10. Then reducing the output level to ensure that the amplifier output signal within a certain range will not be clipping, to avoid damage to the speaker unit.
