Cleaning
Your S8 subwoofer is designed for years of use with no main-
tenance as long as you avoid exposure of the S8 to moisture or
IJHIUFNQFSBUVSFT5IFIBOEöOJTIFE.%'XPPEDBCJOFUTBSF
very durable and are easily cleaned by wiping down with a soft,
dry cloth. We do not recommend using cleaners or solvents.

Placement
We think you’ll nd your S8 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 S8, 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,
XIJDIJTXIZTVCXPPGFSQMBDFNFOUJTOPUDSJUJDBM3PPNTJ[FBOE
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 placement
aects the sound.
Here are 3 room locations to try out:
*OBDPSOFSoXIJDIXJMMVTVBMMZJODSFBTFTVCXPPGFSMPVEOFTT
Typically the front right and left corners sound the most natural,
though rear corner placement is also an option.

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.

Controls
Your S8 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 prob-
ably 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.
Following is an overview of the subwoofer controls and connec-
tions:

speakers or another subwoofer. This Output is used whenever a
signal is connected to one of the two subwoofer inputs.
Note: The volume level of this Output connection is controlled
by the audio input source, not the volume control on the sub-
woofer.
1IBTF
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 uncommon 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er-
ence go ahead and set the Phase knob to the 0 position.
$SPTTPWFS
The Crossover control is used to set the subwoofer high fre-
quency 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 frequen-
cies 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 speakers.
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 re-
ceiver or processor for correct Crossover settings for your system.

7PMVNF
The Volume control is for matching the subwoofer speaker vol-
ume 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 stron-
gest bass without being“boomy”.
Note: The subwoofer Volume controls the S8 subwoofer level
and does not
control the subwoofer output audio level or the input level vol-

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.

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 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 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 rst 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:
t'JSTUUSZNPWJOHBMMZPVSFRVJQNFOUUPUIFTBNFFMFDUSJDBMDJSDVJU
or AC outlet.
t*GUIFIVNPSCV[[JTTUJMMQSFTFOUUVSOPòUIFQPXFSPOBMMZPVS
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 dierent
outlet.

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.

Controls
The S8 offersthese simple yet versatile controls and features:
Volume
Thevolume control is for matching the subwoofervolume to the level
of your speakers. The bestadvice we can give on volume levels is to
adjust for the strongest bass without being"boomy'~
Note that the S8 volume controls the S8 subwooferlevel only and does
not control the input volume. In other words the overall system
volume is controlled from your music source.
Crossover
The crossover control is used to set the subwoofer highfrequency
cutoff point,which is the point at which the subwoofertransitions to
yourspeakers. For example, if the crossover control is set to the SOHz
mark then the sub will playall frequencies up to SOHz. All frequencies
from SOHz and higherwill then be played by the other speakers.
Fine-tune the crossover setting by ear for the smoothest blend with
your main speakers. There really are no right or wrong setting so don't
hesitate to experiment to fir,d the sound that works for your setup.
Phase
Phase is the degree to which the subwooferand other speakers are
moving at the same time. Once you have chosen a location for your S8,
try flipping the phase switch backand forth while you listen for the
most bass from yourfavorite listening position. Sometimes no
difference will be heard, which is OK as there's no correct phase setting
and it is not uncommon for the subwoofer to sound similar at each
setting depending on your room and sub location.

Inputs
The two audio inputs (3.5mm mini-jackand RCA Left/Right) are
"line-level" inputs for connecting the output of your music source (AV
receiver, preamp, powered speakers, soundcard, TV, etc.) into the S8.
Both inputs are open or active, so you can connect two different
sources at the same time and not have to push any buttons to select
between each.
LFE input
If your preamp or AV receiver has an LFE (Low Frequency Effects)
output, use the Left/LFE input on the S8 rear panel.
Power on/Standby indicator
This indicatorwill be GREEN when an input signal is present (when
music is playing) and AMBER when no signal is present. The S8 will
automaticallyenter Standby mode after 15 minutes if no signal is
detected duringthis time.
Placement
We think you'll find the S8 to be forgiving with regards to room
placement and settings and if you're not an audio expert don't be
intimidated with setting up your subwoofer. There really is no right or
wrong room placement, so try different locationswhile listening to
music to get an idea of how the location affects the sound.
Need to go wireless?
If you need to locate your S8 away from your speakers or music system
check out the Audioengine W3 wireless adapters. The S8 has a built-in
power port on the rear panel that's perfect for powering the W3
wireless receiver.
Cleaning
We don't recommend using any solvents or cleaners on Audioengine
cabinets or speakers. Just wipe down with a soft, dry cloth.
