The TOA M-41S is a professional microphone input module designed for use with TOA's 900 Series or AX-1000 amplifier systems. It features a 600-ohm transformer-balanced input and built-in phantom power for condenser microphone support. Designed for advanced paging and announcement systems, the M-41S includes a voice-activated mute control output, allowing it to automatically trigger mute functions on other system components when speech is detected.
This makes the M-41S an ideal solution for environments where hands-free control and clear, uninterrupted audio are critical — such as conference centers, paging systems, educational facilities, and public address systems.
