High-Fidelity Audio for Your DIY Projects

Don't settle for flat, lifeless sound in your custom audio builds. The XH-M145 Amplifier Board is engineered around the premium YDA138-E chip, renowned for its high-resolution audio processing. It delivers a wide dynamic range that accurately reproduces every detail of your music. Whether you are building a desktop speaker system, restoring a vintage radio, or creating an arcade cabinet, this board ensures crisp highs and punchy lows with minimal distortion.

Ultra-Efficient Class D Power

Traditional amplifiers generate massive amounts of heat, requiring large, space-consuming heatsinks. Thanks to advanced Class D automatic pulse width modulation, the XH-M145 operates with incredible thermal efficiency. It pushes out a robust 12W + 12W of stereo power (into 4-ohm speakers) while remaining cool to the touch. This "chip without heat" design allows you to install the board into tight, compact enclosures without worrying about overheating.

Built-in Safety & Noise Reduction

Reliability is just as important as sound quality. This digital amplifier board features built-in overcurrent protection and thermal protection, safeguarding your speakers and the circuitry from unexpected power spikes or short circuits. Furthermore, the integrated noise reduction technology ensures a high 92% Signal-to-Noise Ratio (SNR), giving you a clean, static-free audio background even when the volume is cranked up.

Plug-and-Play Connectivity

Designed with the maker in mind, the XH-M145 makes wiring incredibly simple. It features a standard 3.5mm audio jack and a 3-pin connector for flexible audio input. The output and power connections utilize heavy-duty green screw terminal blocks, ensuring a secure, solder-free connection to your 12V power supply and speakers. A built-in rotary volume potentiometer (with included knob hardware) gives you instant, tactile control over your audio levels.
