Thermal Overload
All Audioengine powered speakers and subwoofers are protected by
an
internal thermal sensor.
If
they run for extended periods beyond their desig-
nated power rating the thermal sensor will engage and shut
down
the
amplifiers. If this occurs, turn
off
the power switch, lower the volume level,
and wait five minutes before restarting the system. This
is
a normal protec-
tion feature and does
not
indicate a malfunction. A good
tip
in the unlikely
event that a thermal overload occurs
is
to
lower the subwoofer or speaker
output
volume and increase
the
volume
of
your
input
source.
Hum
Adding a new component such
as
powered speakers or a subwoofer
can
bring
out
hum or buzz
that
may
not
have existed before. Your first assump-
tion may be that something
is
wrong
with
the new component
but
this
is
usually caused by a "ground-loop" in your system. Consider these tips for
possible solutions:
First
try
moving your
equipment
to
the
same
electrical circuit or
AC
outlet.
If
the hum or buzz
is
still present, turn
off
the power on all components
in your system and remove all connections
to
and from your Audioengine S
speakers. Then plug the
AS
speaker
AC
cable back in, turn on the
AS
power
switch and check for hum.
If
the
hum
is
still audible then
try
plugging the
AS
speaker power cable into a different outlet.
If
the hum goes away when the interconnect cables are disconnected, the
noise
is
likely coming from another component in your system. Add each
component back one piece at a time and the one
that
causes the system
to
hum
is
likely the source
of
your noise.
A common ground-loop source
is
cable
TV
or satellite cables.
If
the hum or
buzz persists after trying the previous tips, disconnect
the
coaxial cable from
your cable box,
TV,
or
DVR
and
if
the hum goes away the cable
is
the
cause.
