Please note that in stereo operation both channels are always
processed by one single control voltage generated from a mix
of both signals. This means you should only compress adequate
stereo material like sum signals in this mode - dissimilar sig-
nals like a bass drum in one channel and a synth pad in the
other will not give you the intended 'dual mono' results.
