Understanding the Changes

VGA Channel

Several key adaptations are made to the mixer chan-
nels in order to accommodate the selected surround
mode. These changes are reflected in both the
and the screens.

The Panner becomes a dot that

can be pulled, using the mouse, in a 360 degree field.
In traditional surround mixing for film, the center
channel is reserved for dialog only. This ensures that
the dialog is always easily understood, because no
music or effects are sent to that channel. The
key removes the Center channel as a possible
Center
output (thus ensuring that none of your music or
effects bleeds into your dialog channel). Once
is selected, the panning paradigm for the chan-
Center
nel becomes Quad (with the exception that the Boom
send still works).
There is a slider labeled

On the screen, the

ules (pictured here) are updated. As well, on the
screen, the pan and buss modules for each channel
are also updated.
Taken individually, Vertical divergence sets the dis-
tance from the front speakers to the rear speakers,
while Horizontal divergence sets the distance from
side to side. It acts as if at a lower divergence setting
you were physically moving the speakers closer
together, and that at a higher setting you were physi-
cally moving the speakers further apart.
TIP
To illustrate this, set both the vertical and horizontal
divergence to zero. You can pull the dot wherever you
wish, but the actual signal moves nowhere.
