Product Description
TOA M-61S Microphone Input With Compressor And Removable Terminal Block
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
