Stereo Effects
Return Section
There are eight stereo effects returns incorporated into the Xtramix.
Each of the effects returns are individually assignable, in stereo or
mono, to the eight subgroups. Each return channel also incorporates a
stereo return level control, pan/balance control, stereo/mono select
switch and in-place solo switch.
When not being used for an effects device, it is perfectly acceptable to
connect a synth or sampler to an available effects return.
In order to monitor any active effects return at the Xtramix's monitor
and program feeds, it must first be assigned to a subgroup or subgroup
pair (refer to the Subgroup Assign Section). The only exception to this
rule is when an effects return is soloed. Soloing an effects return will
yield the same results whether it is assigned or unassigned.

This control is a dual rotary potentiometer that simultaneously and
equally adjusts both the left and right channel levels. A Return Level
setting of approximately two to three o'clock will yield an adequate level
of effect when matched with an effects unit that is properly operated at a
professional input/output level of +4dbu.
This control when used in conjunction with the Channel Subgroup
Assign Switches, allows the effects return to be assigned to any of eight
individual subgroups or any of four subgroup pairs. When an effects
return is operated in the stereo mode, this control acts as an odd/even
(left/right) balance for the selected subgroup pair.
If the effects return is operated in the mono mode (see Effects Return
Mono Switch), then this control acts as a traditional assign pan for the
selected subgroup pair. When panned to the left this control allows a
mono signal to be assigned to any odd subgroup (1,3,5,7). When
panned to the right it allows a mono signal to be assigned to any even
subgroup (2,4,6,8). When placed to its center position, the mono signal
may be assigned to an odd/even subgroup pair.
Effects return channels and input channels do not automatically
mix to the program, monitor, and headphone outputs -- They must
be assigned to a subgroup first. Once assigned to a subgroup, the
monitor level and pan for that respective subgroup is then adjusted
to produce a stereo mix to the program, monitor and headphone
outputs.
This yellow LED illuminates when the Effects Return Stereo/Mono
Switch (see below) is depressed. This indicates that the left and right
signals are being summed together creating a mono composite.
