3.1 Once the amplifier has passed the Light-up-and-Play and Burn-in tests, remove the unit
from the test station and place it on a test bench.
3.2 Connect a doubleshot speaker to each output channel. If you cannot source these speakers,
you may use any 8 ohm, single driver loudspeaker.
3.3 Connect the audio source or audio signal generator to the audio input A connector. Be sure
to wire the connector correctly. Refer to the wiring diagram on page 9 of this manual if needed.

sofware. You should see the window at right,
with the amplifier in it.
Using the ControlSpace Designer software
or the amplifier’s front panel controls, map

CSD, you should see a graphic of the ampli-
fier.
