Wall-mount amplifier with touchscreen

The Monoprice 40 W Wall Mount Amplifier combines a 3-inch TFT touchscreen, Bluetooth 4.1, USB, microSD, FM radio and line-level aux inputs in a single Decora-style chassis. It delivers 40 watts per channel with ultra-low 0.03% total harmonic distortion for clean sound reproduction.

Suits whole-home audio integration

This unit fits installations that need in-wall wiring and RS-485 connectivity for centralised control via the included IR remote or touchscreen. Builders who require multi-channel surround decoding, HDMI switching or network streaming without RS-485 should consider other product categories.

The amplifier provides 40 watts of power with a measured 0.03% total harmonic distortion at 1 watt into 8 ohms, defining its output capability and clarity for background music or paging applications.

Questions about this item

What maintenance will the touchscreen or IR remote need over time?

The 3-inch TFT touchscreen has no user-serviceable parts; keep it clean with a dry cloth. The wireless IR remote runs on standard button cells — replace them when range drops.

What limit appears first during continuous 40-watt playback?

The amplifier is rated at 40 watts with 0.03% THD at 1 kHz into 8 ohms; sustained full-power output will hit that thermal ceiling before any other constraint.

How much heat or noise does the unit produce when mounted and running all day?

The Decora-style wall mount uses passive convection cooling with no fan, so it generates only mild warmth and no audible noise during extended operation.
