3: Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection

4: Small size

5: cost-effective

Product name: 2.1 channel bluetooth audio power amplifier module

Product Model: ZK-TB21

Bluetooth version: 5.0 (unblocked, 10 meters)

Input Sensitivity: 500mV

Input method: AUX+Bluetooth

Number of channels: 2.1 channels

Power Amplifier Chip: Made in China

Adapter power supply: DC 12~24V/5A or above (the higher the voltage, the greater the output power)

Adapter speaker: 20~100 W, 4~8Ω

Output power: left and right channels ≤ 50W

Subwoofer≤100W

Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection

Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient will there be enough output power!!!

The higher the power supply voltage, the greater the output power, the smaller the speaker impedance, the greater the output power!!!

Please make sure that the power of the adapted power supply is greater than the actual working power of the power amplifier!!!
