TOA M-01S Balanced Microphone

The M-01S is a microphone input module for TOA's 900 series mixer/amplifiers and compatible equipment. It gives one amplifier slot a transformer-balanced microphone input on a removable screw-terminal block, the wiring choice installers prefer for permanent, hum-free connections. Adjustable gain from 32 to 52 dB matches it to dynamic or condenser microphones, and switchable phantom power feeds condenser elements directly.

High-cut and low-cut tone filters trim the top and bottom of the band to keep paging speech clean and help control feedback. The module plugs into any open 900 series input slot, so a system can be configured to the exact microphones on hand. It ships as an add-in card for the amplifier.
