INSTALLATION
The Model 5044 Matrix Mixer from Protech Audio is designed
to be mounted in a standard 19 inch wide EIA rack. Each
unit requires 1.75 inches of vertical rack space. The steps
for installing the unit are as follows;
Mount unit in rack, using four machine screws of sufficient
tensile strength to support unit properly.
Terminate all audio inputs and outputs, using double conductor
shielded cable, as shown on facing page. The diagram on the
facing page shows balanced line configurations. For unbal-
anced lines terminate as shwon below

ALIGNMENT
All four models have been shipped from the factory adjusted
for unity gain. Applying a signal to input #1 will result in the
same level signal appearing on each output. This is true of any
input to any output.
Adjusting the input #1 trimpot on Output#1 section will not
effect the input #1 signal on outputs 2 thru 4. Each input signal
should be adjusted while monitoring each output individually.
Each input section contains a slide switch that controls a 10dB
pad. The Model 5044 is shipped with the pad in place. If more
gain is required it is necessary to remove thecover to access the
pad slide switches. See page 3 for cover removal instructions.
Each input section also includes a push-on RED jumper that,
when in place, provides 10dB of gain. Removing the jumper will
reduce the input gain by 10dB. The Model 5044 is shipped with
the jumper in place.
See page 4 for pad switch and jumper locations.
