Speck Electronics Xtramix - Manual (Page 35)

This standard 1/4" stereo phone jack will accommodate most popular
stereo headphones.
The tip of the stereo jack is the left headphone signal, and the ring of the
jack is the right headphone signal.
This feature of the Xtramix allows an external Stereo Cue (otherwise
known as headphone or foldback) mix to be integrated into the
Xtramix's monitor and/or headphone feeds (see Solo to Monitor Switch,
rear panel). This makes it possible to customize a balance between the
Xtramix's stereo mix and, for instance, the cue feed from a studio
control room.
The Cue Return is accessed via two unbalanced 1/4" TS phone type
connectors. For more on these connections, see their rear panel
descriptions. Also, as the source for such a signal is most likely the high
level output of a power amplifier (via a dedicated headphone box), the
input sensitivity of the Cue Return has been calibrated accordingly.
Do not attempt to connect the speaker terminals of any power
amplifier directly into the Cue Return of the Xtramix.
The Stereo Cue Return Section includes the return level control, the
return pan control, and the return mute switch. The Cue Return may be
operated in mono when a single signal is plugged into the left input jack.
This dual potentiometer controls the level of an external stereo cue
source and returns only to the Monitor and/or the Headphone outputs.
This control allows the Cue Return to be panned anywhere in the stereo
perspective.
This switch allows Muting of the Stereo Cue Return. Enabling this
switch removes the stereo cue return signal from the Monitor and
Headphone outputs.
