STEREO RETURNS
There are four Stereo Returns, which have similar controls but different routing
configurations to provide the maximum flexibility. Each Return has an
unbalanced stereo input on 3-pole A gauge (TRS) jacks. If a mono source is
to be used, plugging into the Left jack automatically feeds the signal equally to
both sides of the Return.
1 LEVEL
The LEVEL control sets the overall signal level, and enough gain is available to
match both +4dBu and -10dBV sources. Rotation clockwise increases the gain
of the input.
2 AUXILIARY SENDS
Each Return may access Aux 1 (Pre-fade) and one of the post-fade sends.
Returns A & C feed to Aux 3 and Returns B & D feed to Aux 4. The controls
should be turned fully anticlockwise when not in use.
3 BALANCE
This control sets the amount of the channel signal feeding the pairs of Groups
or Mix, allowing you to balance the source in the stereo image. When the control
is turned fully right or left you feed only that side of the signal to the destination
selected by the Routing switch (see below).
4 PFL
When the PFL (Pre-Fade-Listen) switch is pressed a mono sum of the pre-fade
signal is fed to the headphones or monitor output, replacing the selected source.
The PFL LED on the Master section illuminates to warn that the headphones,
monitor and right bargraph meter are now responding to the PFL/AFL selection.
5 ROUTING
This switch selects either a pair of Groups (switch released) or Mix (switch
pressed) as the destination for the Stereo Return signal after it has passed through
the BAL control. Returns A & B route to Groups 1 & 2, and Returns C & D route
to Groups 3 & 4. The left return signal feeds the odd-numbered Group or Mix
Left, while the right return signal feeds the even-numbered Group or Mix Right.
