Bogen Communications MIC1X
XLR Balanced Mic Input Module


The MIC1X is a transformer-balanced, low-impedance microphone input module.

Microphone Input Module (MIC1X): The MIC1X module has a transformer-isolated, balanced input with XLR connector. It interfaces with low-impedance dynamic microphones. It also interfaces with electret condenser microphones and has an internal 24V DC phantom power supply to provide the bias supply that is selectable by a PCB jumper. The module has a gain/trim control that will allow the gain to be adjusted from 28 dB to 62 dB of gain. It has the ability to mute lower priority modules and be muted by higher priority modules. The module is able to assume any of 4 priority levels.

The module has a VOX/gating circuit to control muting of lower priority modules and its internal gating circuit with separate controls for gate threshold and duration. It has a built-in limiter to limit the maximum output level of the module, with a threshold control. The module has bass and treble controls with cut or boost of 10 dB at 100 Hz and 10 kHz, respectively. The module’s output is assignable to either or both of two mixing buses.
