71. AFL Solo Switch
The AFL switch allows you to hear the Group signal
through your headphones or monitor outputs. This
comes after the Group Fader and before the MUTE
switch, so you can hear the relative signal level on each
Group even when they are muted.
When you engage the AFL switch on two consecu-
tive odd/even Groups (i.e., 1 and 2, 3 and 4), the soloed
signal appears in stereo in the headphones and monitor
outputs. This is useful when you are using a pair of Group
Sends in stereo to feed an in-ear monitoring system.
Remember, PFL solo mode always overrides AFL solo
mode. If you engage a PFL solo switch on a mono or
stereo channel, the AFL solo is disconnected from the
headphones and monitor outputs and replaced with the
PFL signal. The Rude Solo LEDS below the SOLO meters
indicate which solo mode is active.
7. MAIN MIX Fader
This is the master fader that control the levels at the
MAIN OUTS.
When MAIN TO MON [51] is selected in the PHONES/
MONITOR Section, the MAIN MIX fader also controls the
main mix level in the PHONES and MONITOR outputs
[46/78].
When the fader is fully down, the MAIN MIX is off.
The “U” marking indicates unity gain, and fully up pro-
vides 10 dB of additional gain. Typically, this fader is set
near the “U” label and left alone, but it can be used for
song fade-outs or quick system-wide mutes.
Rear Panel
This is where all the connections are made to the
Onyx 4•Bus (except the headphones and lamps).
7. MIC Input
This is a female XLR connector, which accepts a bal-
anced microphone input from almost any type of micro-
phone. The microphone preamps feature our new Onyx
design, with higher fidelity and headroom rivaling any
standalone mic preamp on the market today.
The XLR inputs are wired as follows:
Pin 1 = Shield or ground
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
The MIC inputs can accept a balanced line-level input
when the PAD [1] switch on the channel strip is pushed
in (the input impedance is lower than the LINE input).
74. LINE Input
This is a 1/4" TRS connector, which accepts a balanced or
unbalanced line-level input signal from almost any source.
When connecting a balanced signal to the LINE inputs,
wire them as follows:
Tip = Positive (+ or hot)
Ring = Negative (– or cold)
Sleeve = Shield or ground
When connecting an unbalanced signal, wire them as
follows:
Tip = Positive (+ or hot)
Sleeve = Shield or ground
