Cleaning

Your S8 subwoofer is designed for years of use with no maintenance as long as you avoid exposure of the S8 to moisture or high temperatures. The hand- finished MDF wood cabinets are very durable and are easily cleaned by wiping down with a  soft, dry cloth. We do not recommend using cleaners orsolvents.

Placement

We think you’ll find 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 difficult 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 floor coverings do make a difference, however, so try different locations while listening to some of your favorite music to get an idea of how placement affects 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 sacrifice 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 amplifier could be covered.
   Audioengine S8 Features

• Super compact size
• 8” custom downfiring woofer
• Dual RCA and mini-jack audio inputs

Wireless Ready!
If you decide to place your S8 away from your powered speakers or receiver, check out the Audioengine W3 wireless adapters (shameless product plug) or Apple’s Airport Express for highquality wireless options. The S8 has a built- in AC outlet on the rear panel that’s perfect for powering these wireless products.

Controls

Your S8 Powered Subwoofer offers simple yet versatile setting options. After you’ve become familiar with what these settings do, don’t hesitate to experiment with them to  ind the sound that works best with your system.
When you set up your subwoofer for the first 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 orwrong settings.
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 S8 subwoofer. Both inputs are active so no switching is required if you wish to use inputs from two different 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 S8 rear panel.
2) LFE In
If your preamplifier or receiver has an LFE (“Low Frequency Effects”) input or single SUB output connect it to this “LFE  In” inputconnector on the subwoofer.
Note: Most receivers have a  subwooferpreamp mono or stereo  output, so LFE will most likelyremain unconnected. 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 two  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 difference 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 difference go ahead and set the Phase knob to the 0 position.
5) Crossover
The Crossover control is used to set the subwoofer high frequency cutoff 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 from50Hz 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 difference 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.
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 first setting up your system and then adjust to your preferred level using different 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 S8 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 an input signal is present (music playing) and RED when no signal is present (power-saving standby mode). The S8 subwoofer will automatically enter Standby mode after 15 minutes when no signal is detected.

Connections

Power

• Verify that the power switch on the rear panel is in the OFF position before making any connections.
• Verify that the voltage selector switch is set to the correct operating voltage in your area.
• Connect the AC power cord to the subwoofer and the other end into a wall outlet. Do not use the outlet on the back of your Audioengine powered speakers or receiver.

Note: If using a receiver or surround sound processor always refer to the instruction manual for specific setup procedures, options, and warnings.

Setup Diagrams

The diagrams that follow show the most common setup and connection options to connect your S8 to other audio gear.
Option A
Connect a stereo RCA cable from your receiver’s preamp SUB OUTPUT to the S8 subwoofer INPUT.

• If your receiver has a single (mono) SUB OUT, connect an RCA cable from this output to the S8 RCA right (R) input.
• If your receiver has an LFE output, connect an RCA cable from this output to the S8 LFE IN.

Note: Your receiver’s manual should indicate which subwoofer connection is most appropriate.
Option B
Connect a mini-jack or RCA cable from any audio product (iPod, computer, CD player, TV, etc.) to one of the S8 INPUT connectors.

Option C
Connect a stereo RCA cable from your Audioengine 5+ LINE OUT into the S8 subwoofer INPUT. Option D
Connect a stereo RCA-to-mini “Y” adapter cable from your receiver’s SUB OUTPUT into the Audioengine W3 Wireless  Sender. Then connect a mini-jack cable from the S8 INPUT to the  Audioengine W3 Wireless Receiver.

Final Adjustments

1. After having connected your subwoofer in your preferred configuration, 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 S8 so that the subwoofer volume matches the overall volume of your speakers. As mentioned in the previous “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 repeating in order to fine-tune to your taste.

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 off.

• 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 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 onscreen 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 theproblem 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 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 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 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 audible then try plugging the subwoofer 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. 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 dehumidifier will add noise into your wall wiring that could be picked up by your subwoofer or powered speakers. A dimmer switch on a halogen floor 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 filter, plug the unit into a different AC circuit, or in the case of a wireless router just physically move it further away from the subwoofer or powered speakers.
