The XH-M120 PAM8610 Stereo Amplifier Board is an upgraded, user-friendly version of the classic PAM8610 module. At Electrapac, we recommend this specific "XH-M120" variant because it integrates a high-quality volume control potentiometer directly onto the PCB, making it a complete, out-of-the-box audio solution.

Product Overview

This board is a 15W + 15W dual-channel digital amplifier. As a Class D system, it provides high-fidelity sound with over 90% power efficiency. The XH-M120 version is specifically designed for convenience, featuring screw terminals for easy wiring and a pre-installed knob for volume adjustment.

Key Features for Electrapac Customers

• Integrated Volume Control: No need to solder external resistors or potentiometers. The onboard knob allows you to adjust the volume smoothly and includes a power switch function on some variants.

• Plug-and-Play Connectors: Equipped with 5mm Pitch Screw Terminals for speaker and power connections—no soldering required to get your speakers booming.

• High Efficiency & Low Heat: Because it is Class D, it stays cool even after hours of use. It consumes very little power, making it perfect for battery-operated setups.

• Onboard DC Jack: Features a standard 5.5mm DC barrel jack for power input, making it compatible with most 12V wall adapters sold at www.electrapac.com.

• Superior Noise Suppression: The XH-M120 circuit layout is optimized to minimize the "pop" sound during power-on and reduces electromagnetic interference.

Wiring & Connection Guide

1. Audio Input: Connect your audio source via the 3.5mm headphone jack or the 3-pin L-G-R header.

2. Speaker Output: Connect your left and right speakers to the corresponding screw terminals. Warning: Do not connect the negative (-) terminals of the speakers together (Common Ground), as this will damage the PAM8610 chip.

3. Power: Plug in a 12V 2A DC adapter. Ensure the voltage does not exceed 15V, as this can permanently damage the module.
