6 - Surround modes—Modules in the surround mix

screen. The screen below shows a stereo input in sur-
round mode:
Note that the “image” control is unavailable for these
stereo inputs in surround mode, but either of the two
stereo inputs may be selected as a mono input (using
the on-screen buttons in the
MODULE
screen).
To change the module to be edited, use the
SEL
key
of the channel to be edited.
Each channel is shown as a “dot” cursor on a plan of
the current surround mode.
The crossing point of the cursor (i.e. the position of
the module signal in the surround mix) can be
changed with the knobs of POD 1 and POD 3 (these
adjust the left/right position for the odd and even
modules) and the knobs of PODs 2 and 4 are used to
adjust the position from front to rear. These adjust-
ments are made when the row cursor is highlighting
the top row on the screen.
For both the left/right and front/rear position settings,
there are 91 steps, so the left/right setting goes from
L45
through
C
(center) to
R45
, and the front/rear
setting goes from
F45
through
C
(center) to
R45
.
There is another parameter, which determines the
amount of the total “sound-stage”, taken from the
center position, within which the module signal can
be positioned. This is set using the second row of on-
screen PODs.
The values here are set in 4 steps:
25%
(the most
tightly focussed, almost a point source near the cen-
ter), through
50%
and
75%
to
100%
(the whole
of the sound-stage is available).
Using these parameters, it is therefore possible to set
the position of a signal precisely or loosely in either
dimension.
As the space available for positioning the sound
source is changed, the dotted box on the screen
enclosing the available area changes size and shape.
Note also the “bar-graphs” (not meters) by each on-
screen speaker, which give an indication of the rela-
tive level of the signal to each of the output channels
in the surround matrix.
In addition to these positioning controls, in the 5.1
surround mode the sub- level (
SUB LVL
) may be
set with the knobs of PODs 1 and 3 using the bottom
on-screen row of PODs.
The left switch of these PODs is used as an
ON/
OFF
switch to route the module signal to the sub
buss.
Pods 2 and 4 of this row are used to move the signal
source diagonally within the surround area (equiva-
lent to turning the L-R and F-R pan controls simulta-
neously). The diagonal angle is set with the switches
of these two pods.
