AVIS

Placement
We think you’ll nd your AS8 to be forgiving with regards to room placement
and control settings, so if you’re not an audio expert don't be intimidated by
setting up your subwoofer. The most important thing to remember is there
really is no right or wrong room placement for your AS8, but hopefully the
simple tips that follow will be useful.
As subwoofers produce audio in a frequency range below 100Hz, it’s dicult
to hear where these low sounds are coming from, which is why subwoofer
placement is not critical. Room size and construction along with furniture
and oor coverings do make a dierence, however, so try dierent locations
while listening to some of your favorite music to get an idea of how place-
ment aects the sound.
Here are 3 room locations to try out:
1 In a corner– which will usually increase subwoofer loudness. Typically the
front right and left corners sound the most natural, though rear corner
placement is also an option.
2 Along a wall– which tends to give moderate bass performance with
increased audio quality over corner placement.
3 Alongside one of the front speakers– which may blend better with the
overall system, but can also sacrice some subwoofer loudness.
Note: We recommend at least 3 inches of clearance around cabinet with good
air circulation. Never cover the subwoofer or place it where the built-in
amplier could be covered.

possible and the Audioengine S8 (AS8) is designed with the same attention
to detail and operational simplicity as other Audioengine products. Our
goal is to get you to your music as simply as possible without all the“gadget
tinkering” that other products generally require. As with our other past
eorts, we thank all our customers and resellers for helping us create
another great Audioengine product!
Unpacking
Your Audioengine speakers were carefully tested and inspected before
packaging and shipping. After unpacking please check for any damage. It is

Following is an overview of the subwoofer controls and connections:
1 Inputs
The RCA and 3.5mm mini-jack inputs are line-level audio inputs used for
connecting the output of your audio source (receiver, TV, iPod, computer,
etc.) into your AS8 subwoofer. Both inputs are active so no switching is
required if you wish to use inputs from 2 dierent audio sources plugged
in at the same time.
Note: If your receiver has a single (mono) subwoofer output, connect an RCA-
cable from this output to the RIGHT RCA input on the AS8 rear panel.
2 LFE In
If your preamplier or receiver has an LFE (“Low Frequency Eects”) input
or single SUB output connect it to this "LFE In" input connector on the
subwoofer.
Note: Most receivers have a subwoofer preamp mono or stereo output, so
LFE will most-likely remain unconnected.
Audioengine S8 Features
•Super-compact size
•8" custom downring woofer
•Wireless-ready!
•Solid hand-nished, front-ported cabinet
•Auto sleep power saving mode
•Dual line-level inputs (RCA and mini-jack)
•All cables included
•Excellent performance for music, movies, and videogames
•A perfect bass extension for Audioengine powered speakers!
Wireless Ready!
If you decide to place your AS8 away from your powered speakers or
receiver, check out the Audioengine W1 wireless adapters (shameless prod-
uct plug) or Apple’s Airport Express for high-quality wireless options. The
AS8 has a built-in AC outlet on the rear panel that’s perfect for powering
these wireless products.
Controls
Your AS8 Powered Subwoofer oers simple yet versatile setting options.
After you've become familiar with what these settings do, don’t hesitate to
experiment with them to nd the sound that works best with your system.
When you set up your subwoofer for the rst time, you will probably make
adjustments a few times before you hear what you like. Start with the
volume at 50% and keep in mind that as with subwoofer room placement,
there are really no right or wrong settings.

The Crossover control is not active when using the LFE input jack.
6 Volume
The Volume control is for matching the subwoofer speaker volume to the
level of your speakers. Keep the volume low when rst setting up your
system and then adjust to your preferred level using dierent music
and/or video sources. The best advice we can give on matching the
volume is to adjust for the strongest bass without being“boomy”.
Note: The subwoofer Volume controls the AS8 subwoofer level and does not
control the subwoofer output audio level or the input level volume. The
overall system volume (subwoofer + speakers) should be controlled
directly from the audio source (TV, receiver, iPod, etc.).
7 Power On/Standby Indicator
This indicator LED will be GREEN when a input signal is present (music
playing) and RED when no signal is present (power-saving standby
mode). The AS8 subwoofer will automatically enter Standby mode after
15 minutes when no signal is detected.

3 Output
The Output connectors provide a full-range line-level output to speakers
or another subwoofer. This Output is used whenever a signal is connected
to one of the 2 subwoofer inputs.
Note: The volume level of this Output connection is controlled by the audio
input source, not the volume control on the subwoofer.
4 Phase
The Phase control is used to blend the sound of the subwoofer with the
other speakers in your system. Phase is the degree to which the
subwoofer speaker and other speakers are moving in and out at the same
time. Once you have chosen a location for your subwoofer, try turning
the Phase control in small amounts while you listen for the most bass
from your favorite listening position. Sometimes no dierence will be
heard, which is OK. There is no correct Phase setting and it is not uncom-
mon for the subwoofer to sound similar at every setting, depending on
your room and location of the subwoofer. If you don’t hear a dierence
go ahead and set the Phase knob at the 0 position.
5 Crossover
The Crossover control is used to set the subwoofer high frequency cuto
point, which is the point at which the subwoofer transitions to your other
speakers. For example, if the Crossover control is set to the 50Hz mark
then the sub will play all frequencies up to 50Hz. All frequencies from
50Hz and higher will then be played by the other speakers. Fine-tune the
Crossover setting by ear for the smoothest blend with your main speak-
ers. The best setting of the Crossover control will depend on speaker
placement, room characteristics, and personal preference. As with the
Phase control, sometimes little or no dierence will be heard, which is OK.
Note: For surround sound setup refer to the manual for your receiver or
processor for correct Crossover settings for your system.

Note: The overall volume for the sub and speakers together is controlled from
the input audio source.
If using the Sub Out feature on Audioengine 5 (A5) power speakers, the overall
system volume (sub + speakers) is controlled directly from the audio source and
not via the A5 front panel volume control.
Final Adjustments
1 After having connected your subwoofer in your preferred conguration,
set the subwoofer volume to about 50% and turn on the power switch.
Note: Refer to the “Controls” section in this Setup Guide for more in-depth
descriptions of the following settings.
2 Adjust the Volume level of your AS8 so that the subwoofer volume
matches the overall volume of your speakers. As mentioned in the previ-
ous “Controls” section, adjust the volume for the strongest bass without
being“boomy”.
3 Fine-tune the Crossover setting by ear for the smoothest blend with your
main speakers.
4 Adjust the Phase control for the most bass from your favorite listening
position. As mentioned previously it is not uncommon for the subwoofer
to sound similar at every setting, depending on your room and location of
the subwoofer
There are no right or wrong settings but with these simple steps you should
be up and running within a few minutes. Steps 2, 3 and 4 may require repeat-
ing in order to ne-tune to your taste.
Option C
Connect a stereo RCA cable from your Audioengine 5 (A5) SUB OUT into the
AS8 subwoofer INPUT
Option D
Connect a stereo RCA-to-mini “Y” adapter cable from your receiver's SUB
OUTPUT into the Audioengine W1 (AW1) Wireless Sender. Then connect a
mini-jack cable from the AS8 INPUT to the Audioengine W1 Wireless
Receiver.

•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, remove 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 protected by an
internal thermal sensor. If they run for extended periods beyond their
designated power rating the thermal sensor will engage and shut down the
ampliers. If this occurs, turn o the power switch, lower the volume level,
and wait ve 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.
Basic Troubleshooting
No sound from the subwoofer
If there is no sound from the subwoofer, please try the following:
LED indicator does not light up
•Check that the AC power cord is plugged in securely at both ends and
make sure that the power outlet the subwoofer is connected to is
working.
•Check that the power switch on the rear control panel is on.
LED indicator lights up RED but does not turn GREEN
•Recheck the connections to and from the subwoofer. Verify that the
input and outputs are not accidentally swapped.
•Check that the cables from your audio source to your subwoofer are
properly connected. Sometimes the 1/8” audio cables feel as if they are
inserted all the way, but are not.
•Check that the volume knob on the rear panel is not set to minimum
volume.
•Check that the volume level of your audio source in not set to minimum
or powered o.
•If connected to a receiver or processor check settings in the bass-
management menu.
LED turns green, but no sound
•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 dierent locations for your subwoofer.

Troubleshooting continued
Hum
Adding a new component such as your subwoofer can bring out hum or
buzz that may not have existed before. Your rst assumption 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 your equipment to the same electrical circuit or AC
outlet.
•If the hum or buzz is still present, turn o the power on all your compo-
nents 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 audible then try plugging
the subwoofer power cable into a dierent 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. In this case you can get a ground-loop isolator from
Radio Shack or your local electronics store. These are inexpensive and
easy to connect inline with your video cable.
•Sometimes something as simple as a portable heater or dehumidier
will add noise into your wall wiring that could be picked up by your
subwoofer or powered speakers. A dimmer switch on a halogen oor
lamp or a wireless internet router positioned near the subwoofer, for
example, could also be possible culprits.
•The best solutions are to use an AC line lter, plug the unit into a dier-
ent AC circuit, or in the case of a wireless router just physically move it
further away from the subwoofer or powered speakers.
