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

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

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.

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

source diagonally within the surround area (equiva-
