Matrix Outputs
There are two matrix sub-mix sections in ZED-4. The send controls
(black & red knobs) take the post-fade signals from the Group, Left,
Right and Mono mix paths and send them to the Matrix output. Matrix
outputs 1 & 2 are individual mono outputs. There is a master level con-
trol to adjust the overall output level, and an AFL (after fade listen)
switch to check the Matrix mix.
Uses for Matrix outputs include:
Record feeds. Enabling a different mix from the main PA mix to
•
be recorded, where more of the backline sound can be dialled in
to the record mix if it is low in the main PA mix.
Zone feeds. For creating individual outputs for different areas to
•
the main PA arena.
Delay stack feeds. Enabling individual mix and level control of
•
delayed speakers in large auditoriums.
Broadcast feeds for live events that are "on air" or "on line!"
•
The Matrix and the Auxiliary outputs are impedance balanced as stan-
dard from the factory. There is the option to fit balanced drivers at a
service centre convert the outputs to be fully electronically balanced.
Auxiliary Output Master Level controls
The Aux master level controls adjust the overall level of each of the
Aux mixes 1 to 6. The range of control is from off (fully attenuated) to
+10dB.
There is an AFL (after fade listen) switch on each Aux mix to check the
signal after the master level control.
