Surround panning
In addition to stereo and left-centre-
right (LCR) panning, XL8 has three
surround panning modes: quad; left,
centre, right and surround (LCRS); and
5.1 surround. To help you visualise the
surround panning envelope, the
masters detail area of the GUI channel
strip has a spatial diagram (shown
right) that updates when you operate
the panning controls.
The 5.1 panning mode uses six matrix
channels, while quad mode uses four
(left and right on both the front and
surround). Although the LCRS mode
uses five channels (front left and right, centre and surround left and right), both
surround channels are the same. (In an LCRS surround panning arrangement, you can
have a single surround speaker positioned directly behind the listener.)
The sound image is controlled via the
masters sections of the input fast strips and
mix channel strip (shown right). The figure
below shows the recommended
1
5.1 surround
system configuration.

In surround mode, the SIS button routes the channel to the surround buses in much
the same way that the ST button routes to the master buses. Surround panning mode
is selected via the Surround Mode options of the Preferences screen (choose
home
PreferencesGeneral).
