900 Series Microphone Input Modules
Microphone Input with Mute-Receive
M-11S
For Balanced, Low Impedance Microphones. - High and Low Cut Fileters for tone control, 4.2k Hz and 330 Hz, 6 dB/octave. - Phantom Power, +22V DC for condenser-type microphones. Activate by default, cut Jumper J1 to disable. - Responds To Mute Bus Activation, via Mute SEND module or switch-closure. - Responds To Both Mute Bus #1 And Mute Bus #2 By Default (cut jumper(s) to disconnect individual mute bus). - Two Mute Response Modes (cut jumpers to configure): 1. Normally-ON - turns OFF during mute activation (most common) 2. Normally-OFF - turns ON during mute activation (functions as an ON/OFF switch, useful for zone-paging microphones in multi-amplifier systems) - Connector: removable terminal block
Microphone Input with Voice Gate
M-51S
- For Balanced, Low Impedance Microphones. - High Cut Fileters for tone control, 330 Hz, 6 dB/octave. - Phantom Power, +22V DC for condenser-type microphones. Activate by default, cut Jumper J1 to disable. - Voice Gate Function, module OFF until input signal exceeds threshold. - Sensitivity Control - turn clockwise to increase sensitivity (to open gate with lower input signal) and counter-clockwise to reduce sensitivity (to open gate with higher input signal) - Connector: removable terminal block
Microphone Input with Compressor
M-61S
For Balanced, Low Impedance Microphones.- High and Low Cut Fileters for tone control, 4.2k Hz and 330 Hz, 6 dB/octave.
-
Phantom Power, +22V DC for condenser-type microphones. Activate by default, cut Jumper J1 to disable.
-
- Compressor Function Helps Prevent Overload And Distortion, activates when the module's input signal exceeds a preset, adjustable threshold.
-
Compression Ratio: 2:1 (fixed), reduces the module's output signal level to 1 dB for every 2 dB increase in input siganl level.
-
Threshold Control - turn CW to lower threshold (to activate compressor function with lower input signal) and CCW to increase threshold (to activate compressor function with higher input signal).

Connector: removable terminal block
