826 Chapter 35 Working With Surround
Configuring Multi-Channel Effects
The Configuration tab allows you to determine how parameter changes affect the
plug-in instances.
 Link menu: Determines which effects are linked. If you link effects, parameter
changes apply to all effects in the linked group. You can choose between three
groups: A, B, and C. Channels set to none (“–”) operate independently. Each group
features its own tab.
 Bypass button: Click to bypass the channel: It is routed around the effect. This is
useful when individual channels should be exempt from processing by a particular
plug-in.
Note: If the Bypass button of a grouped channel is clicked, all channels in the group
are routed around the effect.
When a multi-channel plug-in is first inserted into a surround channel, it is
automatically pre-configured to match the channel’s surround format, and to make the
best use of the plug-in’s capabilities. As an example: A plug-in with mono and stereo
capabilities is inserted into a 5.1 bus. It is pre-configured as two stereo pairs, with the
addition of a mono center and mono LFE channel. The necessary links and tabs are
created automatically.
Linking Channels
When you link channels, keep the following in mind:
 If you link two channels as a stereo pair, the left channel is always assigned as the
master.
 If one or more channels are added to an existing group, the new members adopt the
values of the group.
 If you assign several channels to an unused group, the setting of the (front) Left
channel is used for all group members.
