Owners guide for DLS T-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.
