Detailed Information About The Product:

Name：ZK-TB21 Bluetooth 5.0 Subwoofer Digital Amplifier Board TPA3116D2 50Wx2+100W 2.1 Channel Power Audio Stereo Bass AMP
Stable performance: with better noise performance, excellent output drive capability and relatively high small signal bandwidth, large power supply voltage range.
Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection
hint: When the audio input is enough and the power supply voltage/current is enough, there will 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 adapter power is greater than the actual working power of the amplifier
Wide range of uses: suitable for high quality and professional audio equipment, instruments, control circuits and telephone channel amplifiers.
It has the characteristics of small size, high efficiency, high power and small heat.
