Parameters: Product Name: 2.2-channel Bluetooth Amplifier Board 75W+75W+145W+145W Product model: ZK-TB22 Suitable power supply: The working voltage range is 12-24VDC, and it is recommended to use a DC power supply with a voltage of 24V and a current of 10A or above. Cannot use 24V battery, fully charged will cause overvoltage. DC power supply is required, AC power is not supported!!! If using a DC/DC boost module, it is recommended to adjust it to 80% of the limit voltage to avoid module damage caused by overshoot or ripple overvoltage!!! Maximum power: Left and right channels ≤ 75W, subwoofer ≤ 145W Compatible speaker: Left and right channels: 20-75W, 4-8 Ω subwoofer: 50-150W, 2-8 Ω Bluetooth distance: transmission distance of 15 meters Input method: Bluetooth+AUX+PC+USB, Bluetooth priority, Bluetooth needs to be disconnected when using audio cable input Number of channels: 2.2, left and right channels+dual subwoofer Protection mechanism: Input undervoltage, overheating, overcurrent, short circuit protection, with input anti reverse protection Product size: Integrated potentiometer 117x116mm, external potentiometer 117x101mm Tip: Only when there is sufficient audio input and sufficient power supply voltage/current, will there be sufficient output power!!! The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!!! Please ensure that the power of the adapted power supply is greater than the actual working power of the amplifier!!!
