MW-42BT-AM is TOA's third generation of audio input panels. It is equipped with Line, Microphone, Aux (3.5mm), USB and Bluetooth inputs, and one Stereo/Monaural balanced output. The in-wall design and elegant appearance make it ideal for saving space and integration to various facilities. The microphone input has the highest priority over the other inputs. Any active input will be ducked by 20dB once a microphone signal is detected. The panel fits in a standard 2-Gang Electrical box (not included), and it requires a power supply (included).
