Mono operation: Connect either input and output 1 or 2 –
both will work identically.
Stereo operation: Connect both inputs and outputs 1 and 2 –
the choice which channel is left and which is right is up to you.
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.
