High‑Fidelity Audio with Low Distortion

This dual‑channel digital amplification board focuses on delivering stable, high‑quality sound reproduction for demanding audio projects. AM interference suppression and onboard filtering technology help maintain extremely low THD levels—down to 0.1% during continuous high‑power operation. Such performance enables clear treble, balanced mids, and fuller bass response compared with typical compact amplifier modules. The stereo output architecture supports left and right channel separation, making the board suitable for HIFI speaker builds, media playback systems, and compact DIY stereo installations requiring consistent audio clarity.

Flexible Input and High‑Power Stereo Output

This Bluetooth audio amplifier board integrates Bluetooth 5.0 wireless input alongside a traditional AUX interface, supporting both wireless streaming and wired audio sources. Up to 100W ×2 output power enables effective driving of 4Ω–8Ω passive speakers rated from 50W to 300W. A physical volume adjustment knob provides direct control over output levels without requiring software configuration. Broad DC 5–27V operating voltage allows use with batteries, power adapters, or embedded electronics power rails across a wide range of custom electronics and multimedia projects.

Stable Power Design with Comprehensive Protection

This stereo amplifier module integrates five high‑quality 470µF capacitors that help maintain stable power delivery and smooth audio output. A dedicated heat sink combined with an efficient power management module supports sustained high‑power operation while improving thermal performance. Protective top and bottom acrylic panels add mechanical protection during installation. Multiple onboard safeguards—including overvoltage protection, undervoltage protection, overheating protection, short‑circuit protection, and DC detection—enhance reliability for long‑term operation in DIY audio equipment and embedded electronics systems.
