28.AUX SEND 1 and 2 (Aux Inputs 1-4) AUX SEND 5 and 6 (Aux Inputs 5-8)

These tap a portion of each channel’s signal out to either an effects processor or for stage monitoring. These go to the same Aux Send buses as the mono channel Aux Sends. The Aux Input Aux Sends are always pre-fader.

Aux Inputs 1-4 send their signals to Aux 1 and Aux 2. Aux Inputs 5-8 send their signals to Aux 5 and 6.

FEEDBACK LOOP WARNING: It is

common to use an Aux Send to route

signals to an external processor, and

then return the signal from the processor via the Aux Inputs. Since the

Aux Inputs on the Onyx 80 Series have Aux Sends of their own, you could accidentally route the Aux Input to an Aux Send that is being returned via that same Aux Input. This will cause a feedback loop, characterized by a LOUD howl or screech through the sound system, followed by howls of discontent from the audience. Be careful with the Aux Sends on the Aux Inputs!

29.AUX 3-4 Switch (Aux Inputs 1-4) AUX 7-8 Switch (Aux Inputs 5-8)

For Aux Inputs 1-4:

Press this switch to send the Aux Input signal to the Aux 3 and 4 buses instead of the Aux 1 and 2 buses. The Aux 1 and 2 knobs for that channel strip suddenly become Aux 3 and 4 knobs!

For Aux Inputs 5-8:

Press this switch to send the Aux Input signal to the Aux 7 and 8 buses instead of the Aux 5 and 6 buses. The Aux 5 and 6 knobs for that channel strip suddenly become Aux 7 and 8 knobs!

30. STEREO Switch

When this switch is up, both Aux Sends are fed a mono sum of the stereo channel’s signal (L+R).

When this switch is pushed in, the two Aux sends become a stereo send, with Aux 1 sending the right signal and Aux 2 sending the left signal. The same thing applies when Aux 3-4 is selected for Aux Inputs 1-4, and for Aux 5 and 6 (and Aux 7-8) for Aux Inputs 5-8.

This is useful for providing a stereo mix for IEM (in- ear monitor) systems.

31. BALANCE

BALANCE adjusts the amount of channel signal sent to the left versus the right outputs. On the stereo Aux Input channels, the BALANCE knob works like the bal-

ance control on your home stereo (panning left turns

 

s’Owner

 

 

 

down the right channel, and panning right turns down

 

 

 

the left channel).

 

 

 

32. MUTE

 

 

 

Press this switch to mute the channel. This discon-

 

Manual

nects the channel’s signal from all the Groups, the Main

 

 

 

 

Mix, and Aux Send buses. You can still solo the channel

 

 

 

in PFL mode when the MUTE switch is pushed in.

 

 

 

33. Stereo Aux Input Fader

 

 

 

The fader controls the stereo channel’s level, from

 

 

 

off to unity gain at the “U” marking, on up to 10 dB of

 

 

 

additional gain.

 

 

 

34. Signal Level LEDs

 

 

 

These LEDs indicate the channel’s signal level after

 

 

 

the GAIN and EQ controls, but just prior to the chan-

 

 

 

nel’s fader. So even if the fader is turned down, you can

 

 

 

see if a signal is present.

 

 

 

If you’ve followed the “Set the Levels” procedure, the

 

 

 

–20 and 0 LEDs should light frequently, the +10 LED

 

 

 

should light occasionally, and the OL (Overload) LED

 

 

 

should not light at all. If the OL LED is blinking fre-

 

 

 

quently, the signal is probably distorted from overdriving

 

 

 

the input. Either turn down the GAIN control or turn

 

 

 

down the signal at its source.

 

 

 

35. GROUP and MAIN MIX ASSIGN Switches

 

 

 

Alongside each channel fader are two buttons referred

 

 

 

to as channel assignment switches. Used in conjunction

 

 

 

with the channel’s BALANCE knob, they are used to

 

 

 

determine the destination of the channel’s signal.

 

 

 

The Aux Inputs are assignable to GROUPS 7-8 and

 

 

 

the MAIN MIX. With the BALANCE knob [31] at the

 

 

 

center detent, the left and right stereo signal is equally

 

 

 

balanced. To feed only one side or the other, turn the

 

 

 

BALANCE knob accordingly.

 

 

 

36. PFL Solo Switch

 

 

 

Like the PFL switch on the mono channels, this

 

 

 

switch allows you to hear signals through your head-

 

 

 

phones or monitor outputs without having to route them

 

 

 

to the MAIN or GROUP mixes. Since this is Pre-Fader

 

 

 

Listen, you can listen to the stereo Aux Input even when

 

 

 

the Aux Input fader is turned down. Unlike the mono

 

 

 

channel PFL, the Aux Input PFL is a stereo signal (post-

 

 

 

balance control).

 

 

 

PFL solo mode always overides AFL solo mode. The

 

 

 

Rude Solo LEDS below the SOLO meters indicate which

 

 

 

solo mode is active.
