Speck Electronics Xtramix - Manual (Page 23)

There are two types of In-Place solo incorporated into the Xtramix:
Absolute and True. All input channel solos are Absolute In-place. This
means that a soloed signal will be perceived in the same stereo or mono
perspective being produced by the instrument itself. The solos on the
effects returns and the monitor channels are True In-Place
and follow the position of the channels pan/balance control.
Unlike True In-Place solo, the position of the input channel Balance/Pan
control will have no bearing on the left/right perspective in the Absolute
solo mode. Additionally, if a stereo instrument is connected to a
channel being operated in the stereo mode (see Stereo/Mono Switch and
Channel Input Connectors description, Rear Panel), then soloing that
channel yields a stereo solo signal. If the channel is set to operate in
mono, then soloing that channel will yield a centered mono solo signal.
The solo listening level can be controlled by either adjusting the Input
Level Control, the Master Monitor or Headphone level, although
adjusting the Master Monitor or Headphone level will not affect any
relative balance created with the Input Level Control.
Be aware that the solo circuit activated by this or any other solo switch
on the Xtramix will feed the Monitor Master and/or Headphones as well
as the Tuner Feed outputs. The stereo program outputs are unaffected
by the solo function.
This bank of pushbutton switches, in conjunction with the input channel
Balance/Pan Control (see above), allows an input channel to be assigned
to any of eight individual subgroups or any of four subgroup pairs.
A channel is “Muted” as long as it is not assigned to any subgroup(s).
When the Subgroup Assign Changeover Switch (see below) is in the up
position, pressing the 1-2/5-6 Assign Switch routes the input channel
signal to the 1-2 subgroup pair. When the Subgroup Assign Changeover
Switch is in the down position, pressing the 1-2/5-6 Assign button routes
the input channel signal to the 5-6 subgroup pair. In the up position, all
signal flow to the 1-2 or 5-6 subgroups is muted.
