Product Overview


Product Description

800Watt 4 Channel Digital Audio Power Amplifier
8Ω Stereo Power: 800W*4
4Ω Stereo Power: 1400W*4
8Ω Bridge Power: 2600W*2


1) Standard 1U high, Ultrathin light weight

2) High-efficiency power supply
The use of active power factor correction APFC technology, improve the use of power efficiency, purify power supply
3)High anti-interference
4) High damping coefficient
The circuit design of this product has carefully selected the components, and selected the high-power MOS tube with low output impedance; also designed the speaker back electromotive force absorption circuit, which is beneficial to control the normal movement of the speaker cone.

5) Excellent heat dissipation performance
This machine not only designs the airflow direction scientifically from the structure, but also carries on the intelligent control to the fan on the circuit; When the temperature is low, the fan rotates at a low speed. When the temperature rises, the wind speed increases gradually

6) Humanized appearance design
Designed with handle, easy to carry; Easy to maintain and clean; The panel is designed with
windproof cotton protective cover.When the power amplifier works for a long time, dust will accumulate on the dustproof cotton. At this time, you can easily remove the screw and take out the dustproof cotton for cleaning

7 The perfect protection circuit ensures the safe operation of the power amplifier.

a, overheating protection/short circuit protection
b, overload protection, overcurrent protection, overvoltage protection

8 Unique audio processing technology:
From all aspects, for audio circuits, from circuit design to component selection, strive to be perfect. Such as the choice of capacitance, MOS tube selection, feedback circuit, compensation circuit, filter circuit and so on, have been carefully debugging,to ensure that the amplifier low distortion, wide band, low noise, playback bass powerful, full alto, treble clear.

9) Powerful load capacity,beyond the imagination of the shock
