Alt 3-4 - Mackie Onyx 1220i Quick Start Manual

Alt 3-4

MUTE/ALT 3-4 SWITCHES
Every time a bell rings, an Angel gets its wings. In a
similar way, every time a mute switch is pressed, that
channel is muted in the main mix and appears in the
alt 3-4 outputs instead.
If you just want to mute the channels, then don't
connect the alt 3-4 outputs to anything.
Muted channels can still be soloed to audition them
in the headphones and control room, and to adjust and
check the channel gain levels.
ALT 3-4 OUTPUTS
These 1/4" TRS jacks provide a balanced line-level
signal that can provide an alternate stereo mix for
recording or subgrouping.
Connect these outputs to the inputs of an amplifi er,
powered speaker, or recording device. If you want to
think up some good uses for the alt 3-4 outputs then go
ahead.
For example, these outputs could be used to send
particular channels to another zone, or you could create
a sub-mix of several drum microphones. The alt 3-4
submix can then be routed to the control room and
phones, by pressing the control room alt 3-4 switch, and
then added to the main mix with the control room
"assign to main mix" switch.
The alt 3-4 output doesn't have a master level control.
All the channels assigned to the alt 3-4 bus are summed
together (post-fader and pan) and sent directly to the
alt 3-4 out.
