Ruth's sister XH-M573 80W+80W+100W 2.1 Channel internal power cable

SKU CH-R8S7-49H0B

A 2.1 channel digital amplifier board delivers 80W per stereo channel and 100W for the subwoofer using a TPA3116D2 chip at 1.2 MHz

  • 1 channel layout delivers stereo plus dedicated subwoofer output
  • 2 MHz switching frequency enables compact high-efficiency design
  • TPA3116D2 chipset provides 80W per satellite plus 100W for bass
  • XH-M573 board integrates full amplifier function in single module

2.1-channel amplifier board

The XH-M573 board uses a TPA3116D2 chip to deliver two 80 W channels and a 100 W subwoofer channel in a single 2.1 layout. It runs at a 1.2 MHz switching frequency and is supplied as a bare PCB for internal installation. The compact design suits custom speaker builds or upgrades where an integrated amplifier is required.

Replaces separate stereo and bass modules

Builders who previously wired discrete stereo and mono amplifiers can consolidate them into this one board, reducing wiring and enclosure space. The jump is worthwhile when a project needs matched channels with a dedicated low-frequency output and the 80 W and 100 W ratings meet the speaker requirements. It is not suited for systems demanding more than two full-range channels or higher per-channel power.

Questions about this item

What speaker impedance does the XH-M573 amplifier board support for its 80 W + 80 W + 100 W channels?

The TPA3116D2 chip on the XH-M573 is rated for 4–8 Ω loads per channel, so use 4 Ω or 8 Ω speakers for the two 80 W satellites and the 100 W subwoofer output.

Which wiring step is most often missed when installing the XH-M573 2.1-channel amplifier?

Connecting the three speaker outputs — left, right and subwoofer — to the correct terminal blocks before applying DC power avoids channel-swaps and protects the TPA3116D2.
