Mute / Alt 3-4
The dual-purpose Mute/Alt 3-4 bus is a Mackie signature.
Naturally, when Greg Mackie was designing our first mixer, he had to include
a mute switch for each channel. A mute switch works just like it sounds:
it turns off the signal by "routing" it into oblivion.
"Gee, what a waste," Greg reasoned. "Why not have the mute button route
the signal somewhere else useful, like a separate stereo bus?" So the Mute/Alt
3-4 buttons on our 1202-VLZ PRO and 1402-VLZ PRO really serve two functions:
muting (duh), and signal routing (oh!), where they act as your gateway to
an extra stereo bus.
Four buses on two-bus boards.
You simply connect the Alt 3-4 outputs to whatever destination
you desire. For instance: When doing multitrack recording, you can use the
Alt 3-4 outputs to feed your multitrack.
When doing live sound or mixdown, Alt 3-4 can be used for subgrouping. Simply
assign multiple channels to the Alt 3-4 mix, engage it in the Source matrix,
and the signals will appear at the Control Room and Phones outputs. If you
want the Alt 3-4 signals to go back into the Main Mix, push the Assign to
Main Mix button. Now, the Control Room/Phones knob becomes a master control
all channels assigned to Alt 3-4.
It's also great for previewing a channel before you bring it into the main
mix, or creating a "mix minus" for broadcast production.
Mute/Alt 3-4 is a Mackie Designs exclusive you'll come to appreciate. Take
your time and play around with it. It will be your friend. Honest.
