TOA Electronics Audio Interface with USB and Bluetooth - MW-41BT-AM

Product Overview

The TOA MW-41BT-AM is an in-wall audio interface panel that consolidates microphone, auxiliary, USB, and Bluetooth 5.0 inputs into a single flush-mount unit for installed sound systems. With a mono balanced output and 24 V phantom power, it connects directly to TOA or compatible amplifiers and mixers, providing a clean, space-saving audio source panel for commercial AV installations.

Product Description

The MW-41BT-AM fits a standard 2-gang electrical box and presents four source inputs at the wall: an XLR microphone input with switchable 24 V phantom power, a 3.5 mm stereo aux input, a USB-A port for MP3/WAV playback from flash drives (up to 32 GB), and Bluetooth 5.0 for wireless audio streaming. A single mono balanced output on an RJ45 connector feeds the system amplifier or matrix mixer. An input selection button cycles through active sources, while independent volume controls and a dedicated mic level control provide front-panel adjustment.

When the microphone input is active, it automatically ducks all other inputs by 20 dB — providing a simple priority function without external processing. The unit is powered by an included AC adapter (100–240 V universal) and ships with a remote control, RJ45 conversion socket, and box mounting screws.
