Features:
1: Power amplifier chip: TDA7498E
2: Protection mechanism: anti-reverse connection, undervoltage, overheating, overcurrent, short circuit protection
3: Widely used
4: Long-life ultra-quiet fan (locked rotor does not burn, no noise)
5: Simple to use and easy to understand


Parameter:
Product name: 2.1 channel Bluetooth audio power amplifier module
Product model: ZK-HT21
for Bluetooth version: 5.0 (unobstructed, 15 meters)
Input method: AUX + for Bluetooth + USB (the dial button to switch modes and songs)
Number of channels: 2.1 channels (left channel + right channel + subwoofer)
Amplifier chip: TDA7498E
Adapter power supply: DC15~36 V (under voltage protection below 9V, 12V power supply can also be supported)
Adapted speakers: 30-200W, 4-8Ω
Output power: left and right channels ≤160w, Subwoofer≤220w
Protection mechanism: anti-reverse connection, undervoltage, overheating, overcurrent, short circuit protection
Product size: 145*126*28mm
Product weight: net weight 327g, including packaging 395g


Package Included:
1* Power amplifier board kit

Tip: 
When the audio signal input is large enough and the power supply voltage/current is large enough, there will be enough output Power!
The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power! Please make sure that the power of the adaptor is greater than the actual working power of the amplifier!
