TOA M-41S Microphone

The M-41S is a microphone input module for TOA's 900 series mixer/amplifiers that adds automatic priority paging to a slot. It provides a transformer-balanced microphone input on a removable terminal block, with switchable phantom power for condenser microphones and high- and low-cut filters for clean speech.

Its defining feature is mute-send: when a signal appears at the input, the module drives the amplifier's mute bus, automatically ducking background music and lower-priority sources so an announcement comes through on top. Paired with mute-receive line modules, it builds a simple priority paging chain without an external controller. The module installs in any open 900 series input slot.
