You can also link channels by assigning them to one of three groups. When you adjust
the threshold or output parameter for any channel assigned to a group, that parameter
is adjusted by the same amount for all channels assigned to the group.
Surround Compressor Parameters
The Surround Compressor is divided into three sections: The Link section at the top
contains a series of menus where you assign each channel to a group. The Main section
includes controls common to all the main channels, and the threshold and output
controls for each channel. The LFE section on the lower right includes separate controls
for the LFE channel.
 Circuit Type slider and field: Choose the type of circuit emulated by the Compressor.
The choices are Platinum, Classic A_R, Classic A_U, VCA, FET, and Opto (optical).
 Detection pop-up menu: Choose whether the Surround Compressor uses the
maximum of all detection signals (Max) or the sum of all detection signals (Sum) to
determine if it is above or below the threshold.
Link Section
 Grp. (Group) pop-up menus: For each channel, choose whether the channel is in
group A, B, or C, or in no group (–). Moving the Threshold or Output Level slider for
any channel assigned to a group will move the sliders for all channels assigned to
that group.
 Byp (Bypass) buttons: For each channel, click to bypass that channel.
