• Adjust the potentiometer selected Hermetically, inputs and outputs use pure copper terminals, wiring is very convenient.
• Selected NE5532, welded IC holder can always replace the amplifier, experience different effects to enhance playability.
• Design of the LED Real-time monitoring the power supply situation.
• PCB board design simple and beautiful, reasonable wiring, making the board has a very high signal to noise ratio, strong anti-interference ability. when no signal input close to the speaker almost hear the noise.
