Surround panning
In addition to stereo and left-centre-
right (LCR) panning, PRO2 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 detail area. The following below shows
the recommended

5.1 surround system configuration.
