The TOA M-41S Microphone Input Module is designed for integrating balanced, low impedance microphones into compatible audio systems. It addresses common audio challenges by providing tone control through switchable high-cut (4.2 kHz) and low-cut (330 Hz) filters, both at 6 dB/octave. For users with condenser microphones, the module supplies +22 VDC phantom power, which can be disabled if not required. Additionally, the M-41S features an input-activated mute function, engaging both Mute Bus #1 and Mute Bus #2 by default, offering flexible system control. Connectivity is managed via a removable terminal block. This module is suitable for IT professionals and system integrators requiring precise microphone input management and tone shaping capabilities within commercial audio installations.
The TOA M-41S is designed for balanced, low impedance microphones. It also provides +22 VDC phantom power for condenser-type microphones.
The module includes high-cut and low-cut filters for tone control. The high-cut filter is set at 4.2 kHz, and the low-cut filter is at 330 Hz, both with a 6 dB/octave slope.
Signal presence at the input terminals of the M-41S module activates both Mute Bus #1 and Mute Bus #2 by default. Jumpers can be cut to disconnect individual mute buses if needed.
