Warning
- Always connect
the safety earth ground.
If you have an AC hum
problem, use the
ground lift switch
you are using an in-wall volume control, please see
Advanced Topics for more information.
4.
Speaker channels are cutting in and out:
a. If using in-wall volume controls, check that they can
handle the power output. See Advanced Topics page
28.
b. If bridging, the amplifier “sees” one-half the stated
speaker impedance rating. Make sure the impedance
is high enough. (See page 28.)
c. There maybe a short in the wires. Suspect a short if
the problem happens only at the highest volumes.
5.
Protection LED is Red:
a. Unplug the unit from AC power, wait two minutes,
then plug back in. This should reset the unit.
b. Something rather serious has happened inside The
Director. Call the AudioControl factory.
6.
Speaker Buzzing or Cracking at high volume:
a. Reduce the equalizer boost in the 40-80 Hz
range.
b. Raise the subsonic filter frequency.
7.
There is no audio input signal, but the Zone Status
LED is still Blue:
a. Check the Signal-Sense defeat switch on the rear
panel as well as in the Ethernet controls.
b. The Zone Status LEDs stay on for 1 to 2 minutes
after the audio signal has stopped to prevent prema-
turely turning off the zone during quiet passages or
disk changes.
8.
The unit is on but you cannot trigger it off
• With the ethernet control, the unit will stay on if
either a 12v trigger is on (or jumpered) or the
ethernet control is set to on.
