2.11.3 Buss Compressor Architecture
The Buss Compressor employs common sidechain processing to all buss contributions
simultaneously. This avoids unwanted modification to panning and balance during
compression gain changes, but it does mean that parameter settings will apply to all main
busses and increased level on any buss will result in increased compression on all outputs.
The Sub channel is treated differently, in that the contribution the Sub channel makes to the
overall compression and the effect that overall compression has on the Sub channel are both
under user control. This means that you can have the Sub channel contributing to the
common sidechain but its own signal is not compressed. Or you can arrange the Sub channel
signal to be compressed but exclude this signal from the common sidechain to avoid
‘pumping’ during loud LF passages. Or you can exclude the Sub channel from both the
sidechain and compression so that it operates independently. The controls allow any
proportional combination of these conditions to be set up as illustrated below.
The SUB TRIM control sets the amount that the Sub signal contributes to the compressor
sidechain. And the SUB PASS control sets the amount that the overall compressor sidechain
will affect the Sub channel output signal.
