RKAmp4 10+10W Audio Amplifier Component List and Instructions
The RKAmp4 stereo amplifier has been designed around the TDA2009A 2 x 10 Watt stereo amplifier
I.C.
The sound signal is inputted into the circuit via a 3.5mm stereo socket
The amplifier has 2 channels of up to 10 Watts per channel
Produces a very high quality sound output
The PCB includes a power switch
The PCB includes a power LED
The PCB uses terminal blocks
Battery powered between 4.5V and 24V
Power is inputted to the PCB via a terminal block or jack socket
Compact design
Low cost
The PCB is a high quality double sided black PCB
A large ground plane is used to aid with dissipating heat
