Amplifier Module 2.1 Class D TPA3116 2x 50W + 100W Bluetooth 5.0 with Volume / Tone / Crossover Frequency Control
This 2.1-channel Class D amplifier module is based on the use of two TPA3116D2 amplifier chips. It is therefore capable of delivering up to 2x50W + 100W, enabling 2.1-channel audio amplification with a passive subwoofer. It offers numerous adjustment options via 5 potentiometers, including volume control, treble tone adjustment, treble level (high-pass), crossover frequency, and bass level (low-pass). It provides 2 input options (via a 3.5mm AUX jack or Bluetooth 5.0). Outputs are available through screw terminals for all 3 channels. As an added feature, solder pads allow remote mounting of the volume control, playback controls, operating mode selection, and more. The module can be powered via a DC jack or screw terminal block and accepts 12-24V DC 3A/4A.
