• Recheck the connections to and from the subwoofer.
Not enough bass from the subwoofer
If the output from the subwoofer is low, please try the following:
• Make sure that the Volume control is turned up.
• Check that the inputs and outputs are connected correctly.
• Experiment with different locations for your subwoofer.
• If your receiver has a single subwoofer connector that is not
labeled LFE, make sure it connects to the subwoofer’s RIGHT
(mono) input connector.
• If the bass is still not enough after checking other tips use an
RCA “Y” cable to connect your preamp or receiver’s single output
to the subwoofer’s RIGHT and LEFT inputs.
• Consult your preamp processor or receiver’s manual and/or on-
screen menus and go through all surround sound setup and bass
management options.
• If playing a movie, check the source material menu to verify
that the desired soundtrack option is selected.
Note: If your subwoofer is connected to a receiver or processor
and you’ve tried all these tips but are still having problems, re-
move the AS8 from the receiver and test using an iPod, computer
or other source to verify that the problem is with the subwoofer
and not the receiver setup.
Subwoofer goes into standby
If your subwoofer goes into standby while music is playing,
please try the following:
• Turn the source signal up and the subwoofer volume down.
• If using with a receiver, turn the SUBWOOFER level up in the
SPEAKER SET-UP menu. After you turn the signal up, turn down
the volume knob on the subwoofer to compensate.
Thermal Overload
All Audioengine powered speakers and subwoofers are pro-
tected by an internal thermal sensor. If they run for extended pe-
riods beyond their designated 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 protection 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 your subwoofer can bring out
hum or buzz that may not have existed before. Your first as-
sumption may be that something is wrong with your subwoofer
or other component but this is usually caused by a “ground-loop”
in your system. Consider these tips for possible solutions:
• First try moving all your equipment to the same electrical circuit
or AC outlet.
• If the hum or buzz is still present, turn off the power on all your
components in your system and remove all connections to and
from the subwoofer. Plug the subwoofer AC cable back in, turn
on the power switch and check for hum. If the hum is still audi-
ble then try plugging the subwoofer power cable into a different
outlet.
• If the hum goes away when the interconnect cables are discon-
nected, 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.
