yournew subwoofer, werecommend you tospend timeandcarefully readthese instructions beforeyou connectand
start up your system.Also refer to the separateASP manual.
What is ace-bass ?
Normally, speaker design is bound to follow the laws of physics. The consequence will be, to get deep bass, the
speakerboxmust bevery large. Withthe ace-bass techniquewe can "change"the lawsof physics inthe way thatthe
driverbelievesit is placed in a much larger speaker box.
Furthermore,theace-basstechnologyimproves thedriver performance.With theace-bass technique,we candesign
smallersubwoofers with deeperand cleaner bass.
2.1 To an amplifier / pre-amplifier with Subwoofer out terminal.
Connecttheenclosed cord from the subwoofer-output of your home cinema amplifier to LFE IN on the
subwoofer. When the LFE input is used, the built inASP module in the subwoofer is bypassed. Note that the
ASP functions are not available with this connection. You can also connect to Line IN. (Then use the enclosed
Y adaptor). In this case theASP module is in use and all ASP adjustments can be made. You can adjust
severalparameters using theASP.
Note: If you connect by LFE, theASP functions are not available.

TROUBLESHOOTING
If you should face any problem with the sub-
wooferfunction,please checkfollowingpoints.
If the problem remains after checking these
points, please contact your dealer.
1. Check that all connections have been made
properly. Check if any of the cables are
damaged or short-cirquit.
2. Audio Pro subwoofers has a sophisticated
overload protection. This protects your
subwooferfrom damages causedby too high
volume setting.
Your Audio Pro subwoofer is designed to
produce music information in the frequency
range below 100 Hz. The human ear is being
devoided the ability to localize sound of these
lowfrequencieswhythe placement ofthesub-
woofer is not critical. Audio Pro subwoofers
steep lowpass filters make the placement
easier to fit into your listening room. However
you can use the nature of the acoustic laws in
the following ways:
1. To get the most amplification of the room itself,
place the subwoofer close to a corner at a
distance of about 10 cm from the walls. If you
get too much bass, move the subwoofer slightly
outfrom the corner.
2. By experimenting with the placement of the
subwoofer, you can optimize the sound quality.
Justmoving the subwoofer0,5 M can
dramaticallychamge the sound balance.
One good rule is to place the subwoofer at the
same wall as the satellite speakers.
3. Never cover the subwoofer or place it where the
built-in amplifier will be covered.
