60. TO MON/PHONES Switch

Press this switch to route the CD/TAPE signal to the

Monitor and Phones outputs when there are no solo

switches engaged. The Main Mix and CD/TAPE signal

is overridden in the Monitor and Phones outputs by any

PFL or AFL solo.

61. BREAK (TAPE TO MAIN)

Press this switch to route the CD/TAPE signal to

the Main outputs. This actually disconnects the Main

Mix signal from the Main outputs and replaces it with

the CD/TAPE signal. This allows you to easily start up

recorded music during a break without having to mute

or turn down the faders on all the channels.

The patch point for the BREAK switch is prior to the

MAIN INSERTS, the COMPRESSOR (if selected), and

the MAIN MIX fader.

6±. STEREO RETURNS AUX Sends

These tap a portion of the STEREO RETURNS signal

out to AUX 1-4. This allows you to send a processed

signal out to another processor if you want, or to add a

processed signal to a monitor mix, or to use the Stereo

Return as a stereo input and still be able to send the

signal to an external processor or stage monitor.

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 pro-

cessor via the Stereo Returns.

Since

the Stereo Returns on the Onyx 4•Bus have Aux Sends

of their own, you could accidentally route the Stereo

Return signal to an Aux Send that is being returned via

that same Stereo Return. 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

Stereo Returns!

you are using the Aux send to go to an effects processor.

This way, when fader changes are made, the “wet” signal

going to the effects processor moves up and down along

with the “dry” signal, maintaining a balance between

them.

The pre-fader Aux Sends are post-EQ by default. How-

ever, an internal jumper is provided on each channel to

change the pre-fader Aux Sends to pre-EQ, if desired.

This requires some soldering skills, so contact Tech Sup-

port for information on how to access the pre/post-EQ

jumpers for the Aux Sends.

57. AFL Solo Switch

The AFL switch allows you to hear the Aux Send sig-

nal through your headphones or monitor outputs. This

comes after the Aux Send GAIN control, so you can hear

the relative signal level on each Aux Send.

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.

58. MUTE

Press this switch to mute the Aux Send output. When

the MUTE switch is pushed in on an Aux Send, you can

still solo the Aux Send.

5³. CD/TAPE Level Control

This knob controls the level of the signals connected

to the left and right TAPE IN jacks. The signal is then

sent to the MONITOR/PHONES output (when the TO

MON/PHONES switch [60] is pushed in) and the MAIN

OUT (when the

BREAK switch

[61] is pushed

in). The CD/TAPE

level control pro-

vides 10 dB of ad-

ditional gain when

turned fully up.
