Owners guide for DLS Sub 3.10 subwoofer
Introduction
Please read this manual fully before unpacking and
installing the product. It will help you to optimise
the performance of your subwoofer.
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 and a small quantity of warm
soapy water to clean the loudspeakers. Avoid
touching the cone of the bass unit. After unpacking,
we suggest you retain all packing material for
future transports.
System
DLS Sub 3.10 is an efficient, active subwoofer with
a built-in 160 W highcurrent power amplifier. The
loudspeaker unit is a specially developed 10” longstroke woofer with a powerful magnetic system.
DLS Sub 3.10 is designed to interact with Hi-Fi
equipment, surround installations and multi-media
systems. The subwoofer allows great freedom in
placement. With the controls you can adjust
crossover frequency, level and phase, which
makes it easy to adjust for the acoustics in your
listening room.

IMPORTANT!
Before connecting electricity to the power supply ,
it is important that the POWER switch is OFF and
check so the AC switch 115V-230V is set at correct
voltage for your country. Connect the subwoofers
input signals befor you switch the POWER switch
to ON.
Connection alternatives:
Surround system connections
Surround amplifier provide a separate subwoofer
line output, use a "Line Cable" from this output to
LINE IN right (R), fig 3. You can also use a "Split
Cable" to connect the subwoofer line output to both
LINE IN, left (L) and right (R), fig 4. The sensitivity
then increases with 6 dB.
2-channel stereo connections
-Line level input
Should your amplifier have separate pre-amplifier
outputs, you should connect those to LINE IN, left
(L) and right (R). Use a "Stereo Line Cable". Your
front speakers remain connected to the
loudspeaker outputs of the stereo amplifier.
-High level input
Connect the speaker outputs of the stereo power
amplifier to ”left HI LEVEL IN” and ”right HI LEVEL
IN” respectively, fig 2.

Placement
The bass reproduction in a room is the result from
many factors. The performance of the subwoofer,
the dimensions of the room and the placement of
the subwoofer. The most important factor is
probably where in the room the subwoofer is
placed. The character will change as you move the
subwoofer around, small changes in positions 20cm can have a significant effect on the sound.
We recommend that you try out what give maximum performance in your room; by a wall, in a
corner or a free-standing position.

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.
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.
EQ switch.
The EQ change the bass roll-off alignment. For 2channel switch off is more suitable, that will give a
dryer and faster sound. For surround at high level
or/and demanding low frequency response switch
on can be more suitable.
EQ can also be used to optimise the total bass
response in your room. The bass performance is
combination of the subwoofer plus the room
acoustics. Choose the position that best complements your room and the subwoofers positions. A
boomy room switch off can be most suitable, or dry
room acoustic can switch on give the best perform-
ance.
LOW-PASS CROSSOVER control.
The active crossover network of the DLS Sub 3.10
can be continuously adjusted from 30 to 150 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 180°. 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 adjuste the phase.
Start at 0° and then turn it to 180° and start to
adjust from the best sounding end possision, and
again, your ears are the proper instrument to
decide.
