Introduction!
Please read this manual fully before unpacking and installing the product.
It will help you to optimise the performance of your speakers.
Unpacking and maintenance
Your speaker should be treated with the same care you would treat a piece
of furniture. Use only a piece of soft cloth to clean the loudspeakers. After
unpacking, we suggest you retain all packing material for future transports.
Running-in period
The performance of the speaker will change subtly during the listening
period. Please allow your new speakers to play about 20 hours of music
at normal listening level before doing any critical listening.
System
DLS Flatsub 8.2 is an efficient, active subwoofers with a built-in 250 W
digital power amplifier. The loudspeaker unit is a specially developed,
8”, long-stroke woofer with a powerful magnetic system.
DLS active subwoofers are designed to interact with Hi-Fi equipment,
surround installations and multi-media systems. The subwoofer allows
great freedom in placement. With the control you can adjust phase, crossover frequency and level, which makes it easy to adjust for the acoustics
in your listening room.
Connecting power supply
The switch POWER(2) is the ON / OFF switch for the subwoofer. The
POWER switch(2) "OFF" position is used when the subwoofer shouldn't
be in use for some time.
With the AUTO ON / ON switch (4) in position AUTO ON, the subwoofer
starts automatically with the rest of your system and the POWER LED,
on the front panel, glows green. After a period without input signal the
amplifier atomatically reverts to standby, POWER LED glows red.
Setting the AUTO ON / ON switch (4) to position ON will disable the
automatic strart/stop function, the amplifier is on as long as the POWER
switch(2) is set to ON.
CAUTION!
If you hear distortion when you increase the volume this is normally a
sign of overloading the subwoofer and you should immediately reduce
the level. We recommend that you use the volume control with care.
Service
Should your DLS loudspeaker system require service, or if you
have difficulty in achieving the fine performance of which your DLS
loudspeaker system is capable, consult the DLS dealer from whom
the system was purchased. Your dealer has the knowledge required
to provide expert advice and assistance. In case the DLS dealer is
unable to assist you, you are welcome to contact the DLS Technical
Department.

IMPORTANT SAFETY INFORMATION!
1. The AC power cord must be connected to an AC outlet where it
can be easily disconnected from the power source. A fixed installation
of the power cord is not allowed.
2. The subwoofer must be connected to an AC outlet with protective
ground.
3. Do not use this subwoofer in damp areas and protect it from water.

Volume control
This control is used to adjust the balance between subwoofer and
front or satellite speakers. Once you have found a pleasant balance
there should be little need for further adjustments. Trust your ears
and your personal taste to find the correct setting.
Low-pass frequency control.
The active crossover network of the DLS Flatsub can be continuously
adjusted from 40 to 200 Hz. This frequency is the split frequency
between the subwoofer and the front or satellite speakers. A higher
crossover frequency eases the load of the front speakers while a lower
crossover improves the stereo image. As with the level control you
need to try out what suits your equipment, room and ears the best.
Phase control.
This control changes the phase of the subwoofer sound continuously
from 0 to180°. Normal position is 0°, but for reasons of placement it
could occur that subwoofer and front speakers are out of phase at
the crossover frequency.
You recognize this as weak bass reproduction that just barely can be
adjusted with the level control. Instead you adjust the phase. Turn
the control slowly clockwise while playing music until you here the
bass sound improve, your ears are the proper instrument to decide
when the sound is correct.
Bass EQ
This switch gives an increase of the bass sound with +4 dB @40 Hz.
Choose the position that best matches your ears.
Placing in the room:
The Flatsub subwoofers are designed for hanging on a wall, down near
the floor as in the photo, or any other position on the wall. A wall bracket
is included with the speaker. The wall bracket is attached on the wall
as in the drawing below.
Another way is to place it lying under a furniture, for example a sofa.

Connection alternatives:
- SURROUND SYSTEM CONNECTIONS
Surround amplifiers provide a separate subwoofer line output, use a
"Line Cable" from this output to LINE IN left (L), fig. 1. You can also
use a "Split Cable" to connect the subwoofer line output to both LINE
IN, left (L) and right (R), fig.2. The sensitivity then increases with 6
dB. This way to connect is to be preferred.
2-CHANNEL STEREO CONNECTIONS
-Line level input
Should your amplifier have separate pre-amplifier outputs, you should
connect those to LINE LEVEL INPUT, left (L) and right (R). Use a
"Stereo Line Cable". Your front speakers remain connected to the
loudspeaker outputs of the stereo amplifier.
