XH-M120 PAM8610 Dual-Channel 12V Audio Amplifier Module - 15W+15W Class D Stereo Board

The XH-M120 is a compact dual-channel Class-D audio amplifier module built around the PAM8610 integrated circuit, designed to deliver efficient, high-quality stereo sound from a wide 7V to 15V DC supply. It outputs 10W per channel into 8Ω loads (at 13V) and 15W per channel into 4Ω loads, achieving over 90% efficiency with low heat generation—making it suitable for space-constrained enclosures and battery-powered audio projects. The onboard 32-step DC volume control spans a +32dB to -75dB range, allowing precise level adjustment without an external potentiometer. A signal-to-noise ratio of 90dB and THD+N of 0.1% ensure clean audio reproduction, while built-in over-current, thermal, and short-circuit protections safeguard the module under demanding conditions. The board measures approximately 43mm × 47mm and weighs only about 15g, so it integrates easily into portable speakers, car audio upgrades, and educational electronics. Whether the goal is to build a compact home audio system, add stereo sound to a vehicle, or create a DIY Bluetooth speaker, this PAM8610 audio amplifier module delivers a practical balance of power, efficiency, and low-noise performance.
