Troubleshooting
Many problems can be eliminated by
re-checking the wiring and settings
of the unit. If a problem cannot
be solved using the guide below,
please call the AudioControl team
for further assistance, or e-mail us at
techsupport@audiocontrolpro.com
1. No Sound
a. Verify the Power LED is Blue.
b. Verify Protection LED is Off.
c. Verify Zone Status LED is Blue.
d. Verify that the correct input has
been selected in the Web Interface
menus
e. Verify the source unit is operating.
f. Check the speaker connector plugs
on the rear panel are secure.
g. Unplug the power cord and check
the AC Power Fuse on the rear
panel.
2. Protection LED is off, but none
of the Zone Status LEDs are on:
a. Defeat the signal-sense circuits
using the signal sense switch on the
Web Interface Web Interface. All of
the zone status LEDs should turn on.
If they do not, call AudioControl's
customer service.
b. Verify the source unit is operating.
c. Increase the preamp volume if
signal sense is engaged, or just
going steady.
3.
Channel Status LED is Red:
a. Check speaker leads for a short.
Swap speaker connectors on rear
to see if the problem moves with
the wires.
b. If the unit is excessively hot, turn
down the volume and allow it to
cool off. The protection LED should
turn off after a short while. Verify
that any ventilation holes have not
become blocked.
c. The speaker impedance may
be too low. Use an ohmeter to
measure the impedance on the
speaker wires.
4.
Speaker channels are cutting in and
out:
a. If using external volume controls,
check that they can handle the
power output.
b. Make sure the speaker impedance
is not less than 4 Ohms, or 8 Ohms
when used in bridged mono.
c. There may be a short in the wires.
Suspect a short if the problem
happens only at the highest
volumes.
5.
Protection LED is Red:
a. Disconnect power from the unit
for 3 to 4 minutes and reconnect to
power.
b. Disconnect all speaker wires. If
it still turns red, and the unit has
cooled, something rather serious
has happened inside the unit.
Call AudioControl's lonely folks in
customer service.
c. We are going to need a bigger
boat.
