GENERAL INFORMATION SAFETY INFORMATION
Thank you …
Thank you for buying the new Philips Active Subwoofer.
We have designed and tested the subwoofer to provide
you with the latest technology and high quality sound.
Follow these instructions to adjust and operate all the
functions of your new subwoofer. Please read and perform
the instructions in the order shown.
General Information
This product complies with the radio interference
requirements of the EU (European Union).
• The typeplate (which contains the serial number) is
located at the rear of the subwoofer.
1 All unnecessary packaging material has been omitted.
We have tried to make the packaging easy to separate
into three mono-materials:
– cardboard (box)
– expandable polystyrene (buffer)
– polythene (bags, protective foam sheet).
2 Your subwoofer consists of materials which can be
recycled and reused if disassembled by a specialized
company. Please follow local regulations on recycling
your old subwoofer.
Accessories (Supplied)
– AC power cord
– Speaker wires (1 pair)
– Subwoofer-In cinch cable
Safety Information
• Before switching on the subwoofer, check that the
operating voltage indicated on the typeplate (or the
voltage indication beside the voltage selector) of your
system is identical with the voltage of your local power
supply. If not, please consult your dealer. The type plate
is located at the rear of the subwoofer.
• When the subwoofer is switched on, do not move it
around.
• When switching on or off an amplifier or other
equipment, lower the volume of the amplifier to
minimum to avoid damaging the subwoofer.
• Be careful when setting the volume control of your
audio amplifier to avoid an excessive output power.
• Place the system in a location with adequate
ventilation to prevent internal heat build-up in your
system.
• Do not expose the system to excessive moisture, rain,
sand or heat sources.
• Clean the cabinet with a soft cloth lightly moistened
with water. Do not use any type of abrasive pad,
scouring powder or solvent such as alcohol or benzene.
• Under no circumstances should you repair the unit
yourself, as this will invalidate the warranty.
• To disconnect the system from the power supply
completely, withdraw the AC power cord from
the wall socket.

• Install the subwoofer wherever you like because with the bass sound range reproduced
from the subwoofer (below 150Hz), human hearing cannot detect the direction and
position in which the sound is being produced.
• Also, since the feeling of stereo is lost with bass frequencies, a single subwoofer is
enough for reproducing the bass of stereo channels. However, you may install more
than one subwoofer if your system has more than one subwoofer out jack.
• To obtain a better bass reproduction, we recommend that you install the subwoofer on
a solid floor where resonance is unlikely to occur.
• Always place the subwoofer vertically, keeping a few centimeters from away the wall.

• Do not place an object on the subwoofer or sit on it.
• If the subwoofer is placed in the center of a room, the bass could be extremely
weakened. This is due to the influence of the standing wave of the room. If this
happened, move the subwoofer away from the center of a room or eliminate the cause
of the standing wave, by installing a bookshelf on the wall, etc.

You can adjust the subwoofer
to suit the sound level of your
front speakers. Reinforcing the
bass sound gives you a greater
sense of atmosphere.

amplifier until the sound
from front speakers is not
distorted. If it is distorted, the sound from the
subwoofer will also be distorted.

Turn off these reinforcement or adjust the volume of your audio amplifier or adjust the subwoofer level control and
frequency cut level.
In case color irregularity is observed on the nearby TV screen
With the magnetically shielded type of the speaker system, the speakers can be installed near a TV set. However, color
irregular may still be observed on the TV screen depending on the type of your TV set.. If color irregularity is observed:
™ Turn off the TV set once, then turn it on after 15 to 30 minutes.
If color irregularity is observed again....
™ Place the speakers further apart from the TV set.
