LHD3800
LIHUI
1) Standard chassis 1U high, Ultrathin light weight
2) High-efficiency power supply
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
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, soft start,
b, output DC protection: when the output has DC voltage, in order to protect the speaker, the protection circuit will start quickly and turn off the power.
c overheating protection/short circuit protection
d, overload protection, over current protection, over voltage 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
The machine has strong power, strong shock, not only can carry 4Ohm, 8Ohm, but also can carry 2 Ohm of load; Most power amplifiers can only hold up to 4Ohm.
