Surround panning
In addition to stereo and left-centre-
right (LCR) panning, the PRO6 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
processing area of the GUI channel
strip has a spatial diagram (shown
right) that updates in real time when
you operate the panning controls.
The surround panning modes are
operated via a surround monitoring
system, which uses matrix channels
1 to 6 as the surround bus channels. The channels are muted via six MUTE buttons in
the master bay. PRO6 monitor output connections are via the surround, sub, centre
and front XLRs on the rear panel.
The 5.1 panning mode uses all six 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.)
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.
Figure 15 “5.1 surround panning arrangement” on page 101 shows the location of the
surround MUTE buttons and their matrix channel allocation, and (below) shows the
allocation of the surround MUTE buttons per loudspeaker and the recommended
