ZK-TB21 2.1 Channel Bluetooth 5.0 Digital Power Amplifier Module 50WX2 100W Power Audio Stereo Bass Power Amplifier Board
Product Features:
1: AUX+Bluetooth audio input 2: Subwoofer + left and right channel output 3: Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection 4: Small size 5: cost-effective
Product parameters: 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 Amplifier chip: domestic Adapter power supply: DC 12~24V/5A or above (the higher the voltage, the greater the output power) Adapter speaker: 20~100 W, 4~8¥Ø Output power: left and right channels ¡Â 50W Subwoofer¡Â100W 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!!!
Package list: 1*ZK-TB21 2.1 channel bluetooth 5.0 digital power amplifier module set
