Product Name:2.1 Channel Bluetooth Audio Amplifier Module
Product Model:ZK-TB21
Bluetooth version:5.0(no blocking, 10 meters)
Input Sensitivity:500mV
Input mode:AUX+Bluetooth
Number of channels:2.1 channels
Amplifier chip: TPA3116D2 (with AM interference suppression)
Applicable power supply: DC12~24V/5A or more (the higher the voltage, the higher the output power)
Applicable speakers: 20~100W, 4~8Ω
Output power: ≤50W for left and right channels
Left and right channel ≤ 50W
Subwoofer ≤ 100W
Protection mechanism: over-voltage, under-voltage, overheating, DC detection, short-circuit protection
Product Size:118mm*100mm*22mm
There will be enough output power only when the audio input is enough and the power supply voltage/current is enough!!!!
The higher the power supply voltage, the higher the output power, the lower the speaker impedance, the higher the output power!!!!
Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier!!!!
1 x Amplifier board
1 x Screwdriver
