WL50X4 TDA7388 Solution Vehicle 4-Channel Independent Adjustment HiFi Audio Power Amplifier Board 50Wx4 DC12V-DC15V
Description:
- This product is mainly suitable for 4-channel power amplification for automobiles, 2-channel front+2-channel rear.
- The core is TDA7388. The sound quality is very good. It has its own soft power switch, and the standby current is close to 0mA after disconnection.
- You can set 2-channel input + 4-channel output or 4-channel input + 4-channel output.
- Full sound quality, good dynamic, strong driving power, better than digital power amplifier sound quality.
Specification:
- Power supply voltage: DC12V - DC15V
- PCB size: 80 x 88mm
- Output power: 50W x 4
Usage method:
- When the PCB bottom switch is OFF, the input is divided into front and rear inputs. The volume control is controlled by two independent potentiometers to control the front and rear volume (default factory state).
- When the potentiometer switch at the bottom of the PCB is ON, you can only input the front input signal, and the rear volume potentiometer is turned to the maximum, and the front and rear volume are uniformly adjusted by the front volume potentiometer.
- Switch OFF: 4 Channel Input Mode; 4-channel audio input, 4-channel independent output
- Switch ON: 2 Channel Input Mode; 2-channel audio input, 4-channel independent output.
Package Included:
- 1 x Power Amplifier Board
