Surround panning
There are three surround panning modes: quad, LCRS and 5.1. These are assigned
on a channel wide basis, that is, if the control centre is in 5.1 all channels are
in 5.1. This allows control and distribution of the three surround formats without
re-patching. The same applies to monitoring.
For more information on surround panning, see “Surround panning” in chapter 9.
For information on the set-up for each mode, see Figure 31 “Connections
for a quad surround system (with recommended speaker set-up)”, Figure 32
“Connections for an LCRS surround system (with recommended speaker set-up)”
and Figure 33 “Connections for a 5.1 surround system (with recommended
speaker set-up)” in chapter 29.

Simultaneous generation of stereo masters, mono masters, stereo auxes, mono
auxes, stereo matrices and mono matrices (excluding buses 1 to 6) is possible in
all surround modes. However, SIS™ panning to masters is not possible.
Operation of the monitor system in surround or stereo is a mode selection that
can be made independently or in conjunction with the surround bussing on the
control centre, that is, you can still monitor and solo in stereo, even if you are
producing a 5.1 mix.

Left/right panning control utilises the normal stereo pan pots. Front/back
panning is made possible by taking over the mono level/SIS image control knob
on the control surface (masters section of each channel strip).
Trackball panning and external devices that operate the GUI pointer can also
operate the surround panning on a selected channel.
Bus routing to the six surround matrices remains unchanged, that is, it will be
possible to route and place an image anywhere within the surround stem from
inputs, auxes, aux/group buses and master buses.
Input of pre-recorded surround material is possible from the direct inputs to the
six matrix buses (with no panning available).
No fold down facilities are implemented for externally inputted surround
material. However, a stereo mix can be monitored by switching the monitor
section back to operate in stereo mode sourced from the stereo masters rather
than the six surround matrix modules. This requires an identical stereo mix to be
built at the same time the surround mix is generated, which is normal practice.
When monitoring in surround formats the monitor centre and sub speakers are
muted via the assignable stereo output mutes, while the front and surround
speakers are muted via the A and B monitor mutes.
In normal stereo mode, two assignable outputs — typically the main stereo
left and right — can be patched to the centre and sub XLRs to free up eight bay
modules I/O.
