HM-12 Professional Power Amplifier

High-efficiency, multi-channel Class D amplifier designed for professional audio installations in large venues and fixed sound systems.

The D&D HM-12 is a professional power amplifier designed for demanding sound reinforcement applications. With 12 output channels and Class D circuitry, it offers high efficiency and reliable performance even in large-scale venues such as theaters, stadiums, multi-function halls, and outdoor stages.

Delivering 80W per channel at 8 ohms and up to 160W at 4 ohms, the HM-12 also supports bridge mode with 300W output for higher power needs. Its wide frequency response (20Hz–20kHz) and low total harmonic distortion (<0.05%) ensure clean and detailed audio reproduction, making it ideal for both speech and music applications.

Built-in protection circuits guard against short circuits, open circuits, overheating, RF interference, and DC faults, ensuring operational safety and equipment longevity. With features like variable speed fan cooling and 100dB signal-to-noise ratio, the HM-12 stands out as a high-performance, low-distortion amplifier solution for professional installations.
