The TOA M-01S is a high-performance microphone input module designed for balanced, low-impedance microphones. It features transformer-balanced input via a removable terminal block and includes selectable phantom power (+22V DC) for condenser microphones. High and low cut filters (4.2 kHz and 330 Hz, 6 dB/octave) provide flexible tone shaping for professional sound control. Phantom power is enabled by default and can be disabled by cutting jumper J1. This module integrates seamlessly with TOA 900 Series components and other TOA equipment.
