Bass Treble Bluetooth Amplifier-50W*2

The Bass Treble Bluetooth Amplifier 50W is a compact stereo audio amplification board designed for DIY audio systems, media projects, and embedded multimedia builds. Combining Bluetooth 5.0 wireless audio with AUX input, this high‑efficiency amplifier module delivers up to 50W ×2 output while maintaining low total harmonic distortion as low as 0.1% during sustained high‑power operation. Independent bass and treble adjustment enables precise tone shaping for different speakers and environments. Compatible with passive speakers rated 15W–100W and 4Ω–8Ω impedance, the compact amplifier board integrates easily with controllers and media devices including Raspberry Pi, smartphones, and embedded audio systems.

Note: Adequate output power requires sufficient input signal and power supply capacity. Higher supply voltage generally increases output power, while higher speaker impedance reduces output power under the same voltage and current conditions. When adjusting bass or treble near maximum levels, distortion may indicate excessive gain; reduce the tone control or lower the master volume to restore clean audio.

Independent Bass and Treble Tone Control

This stereo audio amplifier board integrates dedicated adjustment knobs for bass, treble, and master volume, enabling precise sound shaping without external audio processors. The onboard tone control circuit allows low‑frequency enhancement or high‑frequency clarity tuning according to speaker characteristics or listening environments. Such flexibility makes the audio driver board suitable for custom speaker systems, DIY audio equipment, and embedded multimedia installations where tonal balance must be optimized for different enclosure designs and acoustic conditions.

Bluetooth 5.0 and AUX Dual Audio Input

This wireless audio amplifier module supports both Bluetooth 5.0 streaming and AUX wired input, allowing seamless integration with smartphones, embedded computers, and multimedia controllers. Bluetooth connectivity offers a stable transmission range of up to 10 meters in unobstructed environments, while the auxiliary interface provides a reliable wired audio option for development boards and media players. Such dual‑input capability makes the compact amplifier suitable for DIY wireless speakers, smart media centers, and portable sound systems.

Low Distortion High‑Power Stereo Output

The dual‑channel amplifier circuit delivers up to 50W ×2 stereo output while maintaining total harmonic distortion as low as 0.1% under sustained operation. Integrated AM interference filtering enhances signal stability and audio clarity, producing clean and rounded sound even at higher power levels. The high‑efficiency amplification architecture supports passive speakers ranging from 15W to 100W with impedance between 4Ω and 8Ω, enabling flexible speaker pairing across many DIY audio builds.

Comprehensive Hardware Protection

Multiple onboard safety mechanisms safeguard both the amplifier electronics and connected speakers during operation. Integrated protection features include over‑voltage protection, under‑voltage protection, overheating protection, short‑circuit protection, and DC detection. The amplifier board also includes protective top and bottom panels that shield circuitry from accidental contact and improve installation durability in custom enclosures, portable audio devices, and embedded multimedia hardware.

This compact Bluetooth stereo amplifier board enables rapid creation of DIY wireless speaker systems, embedded media players, smart home audio devices, and maker audio projects. Flexible power input, tone adjustment capability, and robust protection mechanisms make the module suitable for hobby electronics, maker prototyping, and STEM audio experimentation.
