Power supply: 2.1 interface DC 8~25V power supply
Channel: 2*50w dual channel (stereo)
Audio source input: Bluetooth connection stereo input, using CSR8633 Bluetooth chip, Bluetooth V4.0
Output impedance: 8 ohms (can drive 4, 6, 8, 16 ohm impedance speakers)
Output power: adding the front-end NE5532 output power is sufficient
DIP switch: It is more convenient to directly adjust the gain of the power amplifier of the subsequent stage, and it is better to push the loudspeaker with larger damping
