Stereo, coupled
This mode, like stereo couple left/right, causes the two compressors to be
mono/stereo
linked together so that they always compress the same amount. But here, the
inputs to the two compressors are fed with the mono and stereo components
of the signal. This means that in general a transient which occurs in both chan-
nels will cause a bit more compression than a transient which only appears on
left or right. The attack and release behavior is determined by the average of
the settings for the two channels.
Modes Table
The mode in which the compressors operate is determined by the combina-
tion of the AGC switch and the Sidechain Link switch. The switch positions re-
quired for each mode is shown in

Question
have the settings for the two channels different?
Yes. Linking the sidechains simply prevents left-right image shifting. Threshold
and input gains can be set independently to cause the compressor to be more
sensitive to instruments which are panned to one side or the other. Output con-
trols can be set separately in order to correct an overall image shift at the out-
put.

Power Switch
This switch determines whether the plug-in is active. When the Power switch
is in the Off position, plug-in processing is disabled and UAD DSP usage is re-

VU Meters
There are two calibrated VU meters, one for each channel. What the Meter
displays is determined by the Meter Switch.
