TOA M-11S Microphone Input with Mute-Receive

The TOA M-01S is a high-performance microphone input module designed for balanced, low-impedance microphones in commercial and professional audio systems. It features transformer-balanced input via a removable terminal block, with phantom power (+22V DC) enabled by default for condenser microphones. Built-in high and low cut filters (4.2 kHz and 330 Hz at 6 dB/octave) provide effective tone shaping.

The M-01S also includes advanced mute bus compatibility, supporting both Mute Bus #1 and #2 by default, with jumper options for selective disconnect. It responds to mute activation via a Mute SEND module or switch closure and offers two configurable mute response modes: Normally-ON (turns OFF when muted) and Normally-OFF (turns ON when muted), making it ideal for zone-paging and multi-amplifier systems.
