XH-M544 TPA3116D2 Mono Digital Audio Amplifier Board DC 12V 24V 150W

Improved Trittschallschalter for Cleaner Sound The XH-M544 mono digital audio amplifier board has been refined with an improved Trittschallschalter, helping to reduce unwanted switching noise during operation. This makes the board a dependable choice for builders and hobbyists who want a straightforward, low-noise amplification stage in their audio projects. Pre-Preamp System for Stronger Signal Handling A dedicated pre-preamp system has been incorporated to enhance the board’s ability to amplify weaker input signals before they reach the main amplifier stage. This results in a more capable and flexible setup, particularly useful when working with sources that deliver a lower output level. Upgraded Single-Channel Digital Amplifier Circuit The board features a new single-channel digital amplifier circuit built around the TPA3116DA, delivering up to 150W of power from a 12V or 24V DC supply. The updated circuit design supports efficient mono amplification, making it well suited to compact speaker builds, portable sound systems, and other DIY audio applications. Improved Audio Cable Noise Performance Attention has also been given to reducing noise picked up through the audio cabling. The improved layout helps minimise interference and hum, allowing the amplifier to deliver a cleaner signal path from input to output. This is especially beneficial when the board is used in close proximity to other electronic components or power supplies. Compact Mono Amplifier Board for DIY Projects Supplied as a set of two boards, the XH-M544 offers a practical and cost-effective solution for a wide range of custom audio projects. Each board remains compact and easy to integrate into existing enclosures, making it a versatile option for builders and hobbyists.
