Mix Bus Meter - Solid State Logic ORIGIN User Manual

As an enhancement to the earlier design, the ORIGIN Mix Bus Compressor has a
2nd order SIDECHAIN HPF (High Pass Filter) with 5 selectable filter frequencies (30,
60, 120, 185 and 300 Hz). Using this control to remove bass frequencies from the
+
sidechain reduces pumping effects when bass heavy mix bus signals 'dominate' the
action of the compressor.
The 'Key from INSERT RETURN' feature switches the sidechain source from the
-
Mix Bus path to the Mix Bus Insert Return allowing an independent key of the Bus
Compressor.
The illuminated COMPRESSION meter displays gain reduction in dB.

diagram on the previous page). There is a switch in the METERS controls in the Master Section (see
page 31) which changes the MIX Meter to follow the monitor source selection (pre
Monitor Level Control, but post AFL/PFL selection). This provides a useful way to
meter other sources on the MIX meter or meter selections from AFL/PFL.
Another useful use for this meter is monitoring/setting Oscillator levels as this meter
is fed directly when the Oscillator TO MIX function is selected (see page 32).
The fast response peak meter has defined markings for +24 dBu and +18 dBu as well as 0 dBu. The meter
has a fast 'peak' response and a slower release time to meter peaks while still showing useful signal levels.
The Mix Meter brightness may be 'dimmed' by holding the MISC section 'SHIFT' switch and simultaneously
pressing the METERS section 'DIM MON METERS' switch.
