Chapter 1: Testing Before Installation
This chapter is intended for experienced technicians to test the Model D-3 prior to
installation. Those without test equipment can begin in Chapter 2: Installation.
1.1 Bench Tests Before Installation
Units shipped to the USA include a 120 VAC power supply. Contact the factory if you
require a different power supply.
1. Place all front panel knobs on the yellow marks. Set the
music system threshold
input
and
auto mix depth
controls fully counter-clockwise.
2. Use the right or left arrow on the Processor to move the cursor to
RESET
and
press the
ENTER
button.
This resets all parameters, except the front panel rotary knobs, to factory default
settings.
To test the controls:
1. Try each channel’s
manual
,
automatic
, and
mute
buttons. Selecting the
manual
button should produce a full gain display. Leave the channels in
auto
mode.
The
auto mix depth
should produce full gain displays on all channels when
rotated fully clockwise. Leave it there for the next two steps.
2. The master
mute
and
override
buttons should fade all channels out.
3. Return the
auto mix depth
control to full counter-clockwise (
auto
).
4. Press and hold down the master
preset
button. Verify that repeatedly pressing
each channel’s
preset
button causes the
preset
LEDs and channel mode buttons
to cycle through their three values. Select
auto
using each channel’s
preset
button.
5. Press and hold down the master
override
button. Verify that the
override
button
on each channel causes the gains to turn full on and off. De-activate each
channel’s
override
button (no light).
If a channel fails to respond normally, first recheck the positions of the front
panel controls. Then cycle the power off for at least 10 seconds, and turn the
power on again. If difficulties persist please contact the factory.
NOTE: A known bug in the Model D-3 system is that a short interruption in power can
confuse the Processor and display an error message in the Processor window.
If this happens, turn the power switch off, mix manually for ten seconds, and
then turn it on again. Normal operation will resume.
