TOA MW-42BT-AM In-Wall Audio Interface With Bluetooth and USB

The TOA MW-42BT-AM in-wall audio interface provides local source selection and volume control for commercial audio systems. It combines Bluetooth streaming, USB playback, an auxiliary input and a balanced microphone/line connection in a two-gang wall panel. Selectable mono or stereo output connects the interface to compatible amplification equipment.

Use this wall-mounted audio source panel in offices, hospitality spaces, classrooms or retail environments where users need accessible connections. Bluetooth accommodates wireless playback, while USB supports stored MP3 and WAV files. For local microphone and music control, configurable microphone priority lowers background audio during speech. The included remote provides another control option, and the recessed installation keeps the interface accessible without occupying equipment shelves.

A removable terminal block carries balanced audio output for integration with installed sound systems. The microphone connection supports selectable phantom power, while the auxiliary jack accepts an unbalanced stereo source. Silver aluminum and black acrylic finishes give the panel a defined appearance for shared spaces. Verify installation depth, connected equipment requirements and source compatibility when specifying the interface; the supplied power adapter supports operation from standard AC mains.
