Owners guide for DLS D-series loudspeakers
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 and a small quantity
of warm soapy water to clean the
loudspeakers. Avoid touching the cone of the
bass unit or treble dome since this may leave
a finger mark or even damage the dome and
spoil its performance. 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
50 hours of music at normal listening level
before doing any critical listening.
Room positioning
2-Channel stereo
The performance of a loudspeaker system in
a room varies with placement. Ideal
positioning of the speakers are 3-4 m apart
and preferably at least 0.5-1m away from side
and rear walls se fig. 1. Avoid distances from
walls that correspond to 1/2, 1/4, 1/6 etc., of
the room dimensions. Seek instead odd
fractions; 1/3, 1/5, 1/7 etc.to minimize effects
of room related resonances.
You will perceive the most accurate sound
picture if you listen from a position halfway
between the loudspeakers, and three to four
metres away. Avoid corner placement as it
leads to colouration and an over-emphasise of
the lower frequencies.
Image stability and stereo perception is
increased if the two speakers are turned
slightly towards the listening position. Try this
out and listen for best stereo image and
centre focus. Objects in the direct sound path
can disturb the coherence of the sound
picture. Try out different positions before
deciding on a final arrangement.
Surround system
Centre speaker positions:
For a front centre speaker position it directly
above or below the screen, depending on
screen height. Optimum is in the same height
as the front speaker sound centre (0.8-1m for
floor standing models)
For wall mounting, there are two holes on the
backside of the speaker for wall mounting with
brackets. One hole for each bracket
Front right and left speaker:
Place the speaker 0.5-1m from the TV. For
large projection screens, space speaker 0.1-
0.5m from screen. Try to follow the 2-channel
position as close as possible in room for best
sound image.
Surround speaker "rear speaker"
Depending on where you sit in the room there
are two ways of presenting the sound image.
Direct or diffuse surround effect.
Direct is when the speaker point at the listen-
ing positions from rear or side walls, in the
same height as front and centre speaker.
For diffuse sound effect, mount the speaker
higher and point them along rear or side wall.

Power handling
DLS recommends using amplifiers within a
specific power range. However, the most
important thing is that the amplifier has
sufficient power reserves for handling peaks
and transient in the music signal
The power rating figure of a loudspeaker is a
very inprecise figure. Since the energy in the
music signal varies, neither peak nor average
value is relevant. A power rating of e.g. 100W
RMS says only that you can play a continuous
tone of 1kHz at this output. It does not mean
that you can turn the volume all the way up on
a 100W amplifier and expect clear sound and
healthy speakers.
The greatest danger to a loudspeaker is
distorded signal. Distorsion in the low
frequency range produces overtones in the
entire spectrum, with an energy that can
easily damage the tweeter units. And since a
more powerful amplifier can play louder
without distorsion, we have the paradox that it
is a greater risk to damage speakers by
playing loud with a smaller amplifier.
Caution!
If you hear distortion when you increase
the volume this is normally a sign of
overloading the amplifier and you should
immediately reduce the output level.
Use of loudness, bass or treble boost
increases the risk for harmful distortion in
the amplifier. We recommend that you use
these controls with care.
Side panels
DLS D-series speaker are designed to be
used with side panels that are avalible in
different finishes. Mount the side panels so
the magnets (black nobs) on the speakers
side, match the magnets on the side panels.
Connections
Make sure to turn off all amplifiers before
connecting your new speaker to your system.
Connect the cable to the terminal. Use the
marking of the cable to ensure that the red or
”+” mark of the amplifier is connected to the
”+” side of the terminal, also marked with red.
We recommend high quality cables, not to
thin, to avoide losses. To reduce the effect the
cable has on the speaker. At high frequency
the inductive component of the cables
impedance can dominate over the DC
resistance and will affect the tonal balance.
Ask your dealer for the best cable for your
needs.

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.

This DLS loudspeaker is warranted to the
original purchaser, against factory defect
in material or workmanship, for a period of
one (1) year from the date of original
purchase. This warranty is valid only in the
country of purchase, to the original
purchaser and is non-transferable.
DLS loudspeakers are music listening
devices and should be used for listening
purposes only. They must not be
connected to any other equipment than
amplifiers within the specified power
range.
DLS cannot be held responsible for
