Aux 1 And Aux 2 - Mackie Onyx 1220i Quick Start Manual

Aux 1 and Aux 2

AUX SEND 1 and 2
The 1/4" TRS aux sends on the rear panel allow you
to send balanced or unbalanced line-level outputs to
external effects devices or stage monitors, independent
of the main mix.
Aux send 1 and aux send 2 are independent of each
other, so you can set up two separate aux mixes. The
aux 1 send output signal is the sum of all the channels
whose aux 1 send control is set to more than minimum.
The aux 2 send is the sum of all the channels whose aux
2 send control is set to more than minimum. The overall
aux output level can be adjusted with the aux send
master controls.
AUX SEND 1-2 and FIREWIRE
The aux sends are always available as FireWire signals
13 and 14 to send to a computer. For example, you can
use your computer with audio production software and
effects plugins, as an effects host. This substitutes
wonderfully for an outboard hardware effects processor.
See page 16 for an example of setting up a software
effects processor using the aux sends and FireWire.
Performance will vary based on system hardware.
PRE or POST
The aux sends can either be pre channel fader or post
channel fader, depending on the position of the pre/post
switches in the aux master section.
For stage monitor work, use PRE, so the stage
monitors do not increase in volume when the channel
fader is adjusted. This allows you to set up the
monitor mix and levels just right, and not have it change
every time a channel level is adjusted. Stage monitors
can either be passive speakers powered by an external
amplifi er, or powered speakers with their own amplifi er.
For external processors, use POST. In this way, the
feed to external processors will vary in level if the
channel fader is adjusted. For example, the level of any
returned effect (like an echo) will also change if the
channel level is changed, keeping them in the same
ratio (wet/dry).
Modifi cation: Pre-EQ Aux Sends
The pre-fader aux sends are post-EQ, so they are
affected by the channel EQ controls. The circuit boards
can be modifi ed so the pre-fader aux sends are pre-EQ
instead of post-EQ. For example, your stage monitors
will not be affected by any channel EQ adjustments.
This modifi cation can be done by an authorized service
center. Contact our technical support chaps for details.

AUX RETURN 1 and 2
These 1/4" TRS stereo input connectors allow you to
add the stereo processed output from external effects
processors or other devices to the main mix. Adjust the
level of the incoming signals with the aux return master
controls.
Alternatively, you can use these inputs to add any
stereo line-level signals to your main mix, so it could be
another line-level source, not just an effects
processor. If you are connecting a mono source, use the
left (mono) aux return input, and the mono signals will
appear on both sides of the main mix.
RETURN to AUX 1
The signals going into aux return 2 can also be added
to aux send 1 by engaging the return to aux 1 switch.
For example, you could add the effects returned from
an external effects processor fed by aux send 2, to your
stage monitors fed by aux 1.
