SMUGDESK XHM542 TPA3116D2 Mono Amplifier Board 100W

SKU CH-H1X0-FNGK6

A compact Class D mono amplifier module delivering 100W into 28 Ω speakers from a 12‑26 V DC supply with a 100 dB signal‑to‑noise ratio

  • 100 W single-channel output drives speakers with authority
  • DC 12-26 V input range suits many power supplies
  • 100 dB signal-to-noise ratio keeps background noise low
  • Onboard aluminium heat sink maintains stable long-term operation
  • Screw terminals and 79×54 mm PCB simplify DIY installation

SMUGDESK XHM542 Mono Amplifier Board

The SMUGDESK XHM542 is a compact Class D mono amplifier board built around the TPA3116D2 chip. It delivers up to 100W of power into a 28 ohm load from a DC 1226V supply. The module measures 79 by 54mm and uses screw terminals for all connections, making it suited for DIY speaker builds and subwoofer projects.

Sustained load thermal performance

An integrated aluminium heat sink handles heat dissipation during extended high-power operation. This design supports stable continuous output for long listening sessions without thermal throttling. A power supply capable of at least 3A output current is required to maintain full rated performance over time.

Upgrade path for passive audio projects

This board replaces the need for a separate amplifier chassis when adding power to passive speakers or converting a passive subwoofer. The jump is worthwhile when a self-contained module with 100dB signal-to-noise ratio simplifies a custom enclosure build. It is not suited for builders needing multi-channel output or wireless streaming features.

Questions about this item

How much heat does the onboard aluminium heat sink handle during all-day playback at 100W?

The integrated aluminium heat sink is designed for effective heat dissipation and stable continuous operation during long-hour use at full power.

What power supply do I need to run the XHM542 at its rated 100W output?

A DC supply between 12 V and 26 V capable of at least 3 A output current is required to guarantee full-power performance.

Can I connect the XHM542 to my existing 8-ohm passive subwoofer?

Yes, the module supports speaker loads from 2 Ω to 8 Ω, so an 8-ohm passive subwoofer will work correctly.
