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 con-
nect 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 sig-
nal that can provide an alternate stereo mix for record-
ing or subgrouping.
Connect these outputs to the inputs of an amplifier,
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 sub-
mix 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.
