INSTALLATIONS
Zone Mixing
Often, the limited number of outputs on a mixing console does not meet the high demands of installed sound systems.
The AuxPander adds eight channels, mixed into any combination of stereo or mono outputs, to cover all of the loca-
tions (or zones) in your installation.
Mix Minus Matrixing
Use the AuxPander for mix minus matrixing, a method used to eliminate feedback in certain distributed installations.
In mix minus installations, each monitor (or group of monitors) receives a different mix. From each mix, you remove or
“subtract” the signal of the source closest to that monitor.
For example, it is common, in large meeting rooms, to position microphones around a table or desk—one for each
person or group of persons. Next to each microphone, there is a small loudspeaker for monitoring the other talkers.
Obviously, each person does not need the loudspeaker to hear themselves or the person next to them. And, because
the microphone and loudspeaker are so close, feedback would occur. You can use the AuxPander to create a mix
minus matrix that removes each talker’s voice from the loudspeaker next to them.
Expand to Fit
Use the AuxPander as a modular unit for large or growing sound systems. Its extensible architecture allows you to
start small and grow. Use multiple units to expand vertically and accommodate any number of inputs into eight out-
puts. Or expand horizontally and add outputs for a fixed number of inputs.

NOTE: The
TIP ASSIGN
switch must be set the same for both AuxPanders. If serial processing is required, pay spe-
cial attention to the
INSERT ASSIGN
switch—you can apply processing to either or both AuxPanders while choosing
whether or not to apply it to the mixing console.
