TDA7381 Class AB audio power amplifier 4x30W

The TDA7381 Class AB audio power amplifier 4x30W is a compact, four‑channel amplifier module built around the TDA7381 integrated circuit. It delivers four independent outputs rated at 30 watts per channel and uses Class AB topology to balance audio fidelity with reasonable efficiency. This amplifier is intended for use where multi‑channel audio amplification is required, such as driving four speakers in compact stereo or multiroom setups.

Engineered for straightforward integration, the module provides individual channel inputs and outputs arranged for easy wiring. Its four‑channel layout supports full, balanced playback across left and right front and rear speakers or any equivalent speaker arrangement. The Class AB design offers reduced crossover distortion compared with single‑ended topologies while maintaining simpler thermal behavior than many high‑power switching amplifiers.

Installation guidance: mount the amplifier to a suitable chassis or heatsink with adequate ventilation to ensure stable operation under load. Use appropriate gauge wiring, a stable power source and correctly rated speaker loads to achieve reliable performance. Where necessary, observe standard precautions for grounding and signal routing to minimize noise and interference. This product is supplied as the TDA7381 module and is suitable for projects or systems that require a reliable four‑channel analog amplifier solution.
