Troubleshooting the Director
Many problems can be eliminated by re-checking the
wiring and settings of The Director amplifier. A variety of
other subjects are discussed in Advanced Topics starting on
page 27. If a problem cannot be solved using this information,
please call the AudioControl factory or check at www.audio

1.
No Sound:
a. Verify the Power LED is Blue.
b. Verify Protection LED is Blue.
c. Verify Channel Status LED is Blue.
d. Verify Source unit is operating and selected via
Ethernet or rear panel switches.
e. Check the Speaker Connector plug on the rear panel.
If the “Output Present” LED is flickering, there is
signal present at this connection.
f. Check the AC Power Fuse on the rear panel.
2.
Protection LED is Blue, but none of the Zone Status
LEDs are on:
a. Defeat the Signal-Sense circuit using the switch
on the rear panel. All of the Zone Status LEDs
should turn on. If they do not, call the AudioControl
factory.
b. Verify Source unit is operating and playing.
c. Adjust the Input Level control counter
clockwise.
3.
Zone Status LED is Red:
a. Check speaker leads for short. Swap speaker connec-
tors on rear to another zone to see if the problem
moves with the wires.
b. If The Director is excessively hot (you cannot hold
your hand on the top), turn down the volume and
allow it to cool off. The Status LED should turn back
to Blue after a short while. Verify that the ventila-
tion holes have not become blocked.
c. The speaker impedance may be too low. Use a meter
to measure the impedance on the speaker wires. If
