Speck Electronics Xtramix - Manual (Page 30)

This is the theoretical heart of the Xtramix. Here is where a stereo mix
of all the subgroups is created, independent of the Bus/Subgroup
Masters. The adjustment of the monitor section's Level and Pan controls
create the stereo mix for the Program outputs, Monitor outputs and
Headphone outputs.
There are three selectable modes of operation for each of the eight
monitor positions:
A. Pre, or independent of the associated Bus/Subgroup Master
(see Monitor Pre/Post switch rear panel).
B. Post, or dependent on the associated Bus/Subgroup Master
(see Monitor Pre/Post switch rear panel).
C. As a stereo/mono input (see Bus/Line Switch below).
Personal requirements will determine whether to select the Pre or Post
mode of operation.

This switch is the source select for the monitor channel. In the up
position, this switch selects its respective mono assign subgroup bus.
When depressed, this switch selects any stereo or mono signal present at
the rear line input connectors.
This knob determines the relative stereo mix level of all signals assigned
to its associated assign subgroup. With the Monitor's Pre/Post switch
(see rear panel) set to Pre, this control will function independent of the
assign Subgroup Master Control. This means it is possible to send a
subgroup signal to, for instance, an external mixing console while
retaining independent control of that same signal for the monitor or
program feeds of the Xtramix. This is considered to be the normal mode
of operation for the monitor section.
The optimum starting point for this control is the three o'clock position.
This should provide for the greatest range of adjustment for the input
channels and effects returns as well as the Monitor Level Control itself.
If the Monitor's Pre/Post switch (see rear panel) is set to Post, then the
Monitor Level Control will follow the Subgroup Master Control. This
means that any level changes made to the Subgroup Master Control will
directly affect the monitor level. This mode of operation would
typically be reserved for situations where the Monitor and Program
feeds need to directly reflect any changes made to a given Subgroup
Master Control.
