Feature:
1. Sound Control: If you're tired of the inherent highs and lows, why not try the treble and bass control knobs! This will give you the feeling of being in a movie theater.
2. Long Transmission Distance: The module uses Bluetooth version 5.0 for longer transmission distance, up to 33 feet in an open environment.
3. Basic Performance: Stereo dual channel output ensures continuous serial high power operation with THD ≤ 0.1%, wide voltage input DC12‑24V.
4. 3.5mm Jack: If your playback device does not have Bluetooth, you can also input audio signal through the 3.5mm headphone plug.
5. Safety Protection: This audio amplifier board has overheat protection, circuit protection, overvoltage and undervoltage protection.
