M-61S Microphone Input with Compressor


- 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
