Features:
Using double-sided alignment,careful layout,signal input section away from the output section.GND part is one-point
The coupling capacitor part is suitable for lengthening the minimum pad 5mm,suitable maximum capacitance of 25mm
The input section to be a high-pass circuit,making the board more stable
The output section using RL circuits (inductors and resistors in parallel) effective protection chip,effectively prevent the induced electromotive force shutdown speaker damage to the chip
The board uses a DC power supply voltage range:±16v-±36v,recommended±32v

Specifications:
VCC=±28V OUTPUT=68W/4Ω,38W/8Ω
VCC=±35V OUTPUT=50W/8Ω
Peak power:135W
SNR≥92db
Conversion Rate:19V/us
Intermodulation Distortion:0.04%
11-pin TO-220 package
Mute function
SPiKeTM protection
Installation note:
The amplifier board can not be directly connected to the transformer output,Transformer output connected to the power supply board first,and then to the power of this board from the power board output,note the positive and negative level can not be wrong!
Using the DC power supply,The smaller the output impedance of the speaker current increases,the greater the heat, it is recommended when the speaker is 4Ω,the voltage suggested the use of ±28V(Transformer for Dual 21V),8Ω speaker the voltage is ±32VTransformer for Dual 24V,the highest voltage is ±35VTransformer for Dual 28V
This Board is Mono channel,Stereo need 2 pieces,Also can according to their own needs to assemble multichannel
When power test,the signal input of the board to take the load, Can't vacant
Board into the chassis,be sure that the chassis shell connect to The input ground on board.Backward input GND do not need to connect the case
Size:7.5x5cm/2.95x1.97inch
Note:
Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid
