Bass Treble Bluetooth Amplifier-50W+100W

The Bass Treble Bluetooth Amplifier is a 2.1-channel audio board delivering 50W per stereo channel alongside a dedicated 100W subwoofer output. Supporting both Bluetooth 5.0 and AUX inputs with on-board tone controls, it is ideal for makers, hobbyists, and educators building custom sound systems or Raspberry Pi audio projects.

High-power 2.1 channel output

The board powers dual 50W left and right stereo channels alongside a dedicated 100W subwoofer channel. It supports 4 to 8 ohm passive speakers rated between 20W and 100W across an operating voltage range of 12V to 24V DC.

Wireless and wired audio connectivity

Connect wirelessly via Bluetooth 5.0 with up to 10 metres of line-of-sight range, or plug directly into the AUX input. The Bluetooth module pairs under BT-WUZHI with an audible tone and automatically reconnects to smartphones or single-board computers on power-up.

Dedicated five-knob acoustic control

Five rotary knobs provide direct control over master volume, left and right treble and bass, subwoofer frequency, and subwoofer volume. The main volume control also functions as the power switch with an integrated LED indicator.

Built-in filtering and hardware protection

Integrated AM interference suppression and filtering keep total harmonic distortion down to 0.1 percent under sustained high output. The board also incorporates protection against over-voltage, under-voltage, overheating, short-circuits, and DC faults.

Included hardware and installation accessories

The package includes top and bottom acrylic protective plates, a large heatsink, five control knobs, assembly hardware, and a screwdriver. Maximum power output depends on your supply voltage, current capacity, and connected speaker impedance.
