High-power D class TDA8920 Digital Amplifier 80WX2 Power Amp 2CH

High-power D class TDA8920 Digital Amplifier 80WX2 Power Amp 2CH

Note:
The R-channel amplifier board is the inverting input and output, When Connected the speaker protection Please note that the output of the Connected Method,
R output of the RO + And L output of the LO- Is GND circuit (ground),
These wires connect to a speaker protection GND (ground).
If you mistakenly RO-as GND (ground), R channel output will cause a short circuit And burn amplifier IC, This is the amplifier board and the general
Different places, Please pay special attention.   
Operating voltage: dual DC ± 15V-± 27V (Recommended voltage: DC ± 20V-± 25V)    
If you use a 4 Ω load, it is recommended supply voltage ± 15V-± 22V.   
Maximum output: OCL 80Wx2 (4 Ω ± 27V), Peak value 100Wx2
Board size is about: Width 81.5mm / depth 107.5mm / height 35mm
(Excluding potentiometer handle dimensions and other protruding parts)
Input hole spacing: 2.5mm
Output hole spacing: 7.6mm    

- The right is the volume potentiometer input signal seat ,2.5mm pitch signal input transposons, Connected audio source, such as: CD, MP3, computers and so on. Board has a left front Super Bass output, The signal is controlled by the volume potentiometer.    
 
More functionality:    
- The amplifier board can be changed to monaural BTL = 160Wx1 (8 Ω ± 27V),Just put the board as long as the Input capacitance of front next to the socket,Printed with "k" of the two welding points Short Connection,Amplifier board Changed to BTL mode.    
- When BTL mode, the signal can be Input from any channel input transposon that the input signal is connected Lin G or Rin G.    
 
Packing including:    
1x TDA8920 digital amplifier
