44. FX to Mon Knobs

These knobs route the pre-fader level of the FX
return to the monitor mix. Use the mon controls
to provide effects to monitors. Slowly add effects
to the monitors by turning the FX to mon knobs
clockwise. These range from
(max, +10 dB).
Because the Onyx8 has one mon send jack,
it also has a single FX to mon knob.

45. FX Master Knob / Fader

Stereo signals come through this FX fader – FX
knob on the Onyx8 – and continue on to the outputs.
They contain the effects' "wet" signals and are mixed
together with the channels' "dry" original signals. This
ranges from (off) to maximum gain (max, +10 dB).

46. FX Mute Switch and LED

When engaged, the internal effects processor
is muted, and its output will not appear on the main
mix, monitor mix or control room outs. This switch
illuminates red when this switch is engaged
as a reminder that the effects are indeed muted.
If this switch is not engaged, then the internal effects
are set free and may be added as required to the main
mix and/or monitor mix.
Additionally, if this switch is not engaged, then
the internal effects may be muted or un-muted
with a footswitch [on all Onyx Series mixers except
the Onyx8].
When power is first applied to the mixer, this LED will
illuminate and the FX will be muted for a second or two
while the little FX gerbils inside settle down.
47. Mon Send Master Level Knob / Faders
These provide overall control over the mon levels just
before they are delivered to the mon outputs. It ranges
from (off) to maximum gain (max, +10 dB).
This is the control you turn up when the lead singer
glares at you, points at his stage monitor, and sticks
his thumb up in the air. (It would follow that if the singer
stuck his thumb down, you'd turn the knob down,
but that never happens.)
The Onyx8 has a single aux mon master.
Additionally, the "Mon Master Fader"
on the Onyx8 is actually a "Mon Master
Knob". But it behaves similarly.

48. Mon Mute Switches and LEDs

When engaged, the monitor output will be muted
and the switch illuminates red as a reminder that
the mon outs are indeed muted.
This is the switch you might engage during load-in /
load-out, in-between bands (and/or sets) or any other
time you don't need the monitors. Then the main
outputs would handle the house music for the audience.

49. Master L-R Assign Switches

[Onyx12, Onyx16, Onyx24]
Alongside the FX and Mon faders are L-R buttons
(also known as assignment switches). They are used
for routing the FX and/or monitor signals to the main
L/R audio bus.
