Name:ZK-MT21 2.1 Channel Bluetooth Audio Power Amplifier Module
Product Description
Power Amplifier Chip: Amp chip
Input Voltage : DC 12V-24V Input Sensitivity: 500mV
Max Power Output: 50W+50W+100W Input Method: Bluetooth &AUX
Channel: 2.1 CH stereo Output Output impedance : 4-8O
Bluetooth Version: BT 5.0 (unobstructed,10meters)
Output power : Left and right channels =50W,Subwoofer =100W
Protection mechanism: overvoltage,undervoltage,overheating,short circuit protection

Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, can there be sufficient output power !!! The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power !!! Please ensure that the power of the adapter power supply is greater than the actual working power of the amplifier !!


Domestic Hifi Chip
This Bluetooth amplifier board features a HiFi power amplifier chip that delivers up to 50W per channel.

Large Heat Sink
The large heatsink quickly dissipates heat, allowing the chip to deliver sustained high power without risk of damage.

Premium Wiring Terminals
Wiring is quick and hassle-free, with no damage to the wires. The 5.5mm x 2.1mm DC input accepts most laptop power adapters.

Adjustable Treble, Bass, and Subwoofer
Endless sound possibilities. Experience a mini movie theater at home — all from a tiny amp.
