in a more aggressive gain reduction while lower ratios will result in more gentle gain reduction.
24. COMP IN SWITCH -
This switch activates the COMPRESSOR circuit. The LED above the switch illuminates when the
COMP is active, turns off when deactivated. This switch controls a gold contact relay.
25. LINK (SC) -
This switch is to activate either a) linking of two m103’s compressor’s side chain circuits – for use in stereo
compression scenarios, or b) to activate external side chain control of the compressor for ducking, de-essing etc...
26. GR METER -
This 10 segment meter displays the amount of gain reduction being applied to a signal in the
compression circuit.
27. VU METER -
This 10 segment meter displays the VU (volume units) at the m103’s output. 0VU=+4dBu.
28. TRIM CONTROL -
The trim control provides 20dB of variable level control at the output of the m103, from -10dB to
+10dB. This control is useful for small level adjustments during tracking or for compression gain makeup.
29. POWER STANDBY SWITCH -
The power switch activates the power supply circuitry. When in the up position, the green
POWER LED will illuminate. When in the down position the m103 is in standby mode. To completely disconnect
power from the m103 remove the AC power cord.
