Beale - A120 - 120W High Efficiency Class D Amplifier

The Beale A120 is a compact, high-efficiency 120W Class D subwoofer amplifier engineered to deliver strong, controlled low-frequency performance while maintaining cool operation under demanding loads. Designed for seamless integration, it accepts stereo or mono line-level input from receivers, preamps, and LFE outputs, making it easy to add a dedicated subwoofer channel to a wide range of audio systems.

A fully adjustable 40–160 Hz low-pass crossover and 0–180° phase control allow precise tuning for optimal blending with full-range speakers and room conditions. The A120 also includes stereo speaker-level inputs with full-band passthrough, enabling amplified audio to continue to the main speakers while simultaneously enhancing low-frequency content. This makes the A120 an excellent solution for multi-room systems and distributed audio amplifiers without dedicated sub outputs.

For convenience and automation, the A120 features audio-sensing power activation, turning on when a signal is detected and shutting down after 15 minutes of inactivity. A 12–24V DC trigger input is also included for systems requiring synchronized control. Compact, efficient, and installation-friendly, the A120 is ideal for in-wall and in-ceiling subwoofer applications.
