TROUBLESHOOTING (continued)

• This indicates that either the wall outlet is not properly ground-

ed, or the wall outlet has a line problem such as a polarity
inversion, (or both). See the above two items for more infor-
mation.

• Check your signal routing from the source to the AC-8CX and

the entire chain of components through which the signal
passes. Secure all connections and double-check that the cables
are connected to the IN and OUT jacks in the proper way.

• Your AC-8CX is equipped with a 15 Amp circuit breaker to pro-

vide overload protection. This breaker will allow up to 1800
watts of power to pass through the AC-8CX to your
components. If the breaker continues to trip after being reset
several times, there may be a short in the system. If no short is
apparent, or the problem is intermittent, this indicates that the
components are drawing more than the 1800 watts the
AC-8CX can supply. Check with your Niles dealer or installer to
see what other iPOWER

™

products can be used in addition to

the AC-8CX to provide sufficient power for your system.

• Many components will create "thumps," "clicks," and "pops"

when they are first turned on. This can happen while their inter-
nal power supply "settles in," which usually only takes a few
seconds or so. This is common, and while annoying, it usually
will not harm loudspeakers. Niles offers several iPOWER

™

mod-

els with features designed to prevent this condition. See your
Niles dealer for more information.

POSSIBLE CAUSES AND TEST PROCEDURE

Both the LINE OK indicator and
the GROUND OK light on the
front panel of the AC-8CX do not
light up.

There is no picture on the TV.

The circuit breaker on the
AC-8CX continues to trip.

There is an audible "thump,"
"click," or "pop," coming from my
loudspeakers during the power-
up function of my AC-8CX.
