ONYX 4•Bus
63. SHIFT Switch
The Stereo Returns have two Aux Send controls.
When the SHIFT switch is up, they route the signal to
Aux 1 and Aux 2, and when the switch is down, they
route the signal to Aux 3 and Aux 4.
64. STEREO RETURNS LEVEL Control
This controls the level of the Stereo Return signal
being sent to the Main Mix bus. It ranges from off to
+10 dB of additional gain when turn fully clockwise.
65. PFL Solo Switch
Like the PFL switch on the stereo channels, this
switch allows you to hear signals through your head-
phones or monitor outputs without having to route them
to the Main Mix. Since this is Pre-Fader Listen, you can
listen to the Stereo Return signal even
when the Stereo Returns Level control is
turned down. The Stereo Returns PFL is a
stereo signal, and therefore retains its left
and right stereo image in the headphones
and monitors, and appears on both LEFT
and RIGHT meters.
Group Section
There are four group masters (or sub-
masters, if you prefer) that feed the four
group outs [85].
66. PAN
Note: The Group PAN control works
only when the MAIN MIX switch is en-
gaged [70].
PAN adjusts the amount of signal sent
to the left versus the right outputs.
With the PAN knob hard left, the signal
feeds the MAIN LEFT output, and with
the knob
hard right, the signal feeds the
MAIN RIGHT output.
67. MUTE Switch
Press this switch to mute the Group
output. When the MUTE switch is pushed
in on a Group, you can still solo the Group
signal (see AFL Solo Switch [71] ahead),
but it is muted at the Group output [85],
the Main output [82](when the MAIN
MIX assign switch is pushed in), and the
Matrix output [77].
68. GROUP Fader
This fader controls the Group’s signal level, from off to
unity gain at the “U” marking, on up to 10 dB of addi-
tional gain.
69. Signal Level LEDs
These LEDs indicate the Group’s signal level after
the Fader, but before the MUTE switch.
So if the Group
Fader is down, the Signal Level LEDs won’t light.
70. MAIN MIX Assign Switch
Push in this switch to send the Group signal to the left
and right MAIN OUTS. When the PAN control is centered,
the signal is sent equally to the left and right outputs.
The signal sent to the MAIN OUTS is after the Group
Insert, Fader, and MUTE switch.
