Prestige One

User instructions for Qln loudspeakers
Thank you and congratulations for choosing the Qln Prestige One loudspeaker!
We at Qln hope you will get a lot of enjoyment from listening to music and that
you will get very rewarding listening sessions for many years to come.
The Qln Prestige One
The goal of the Qln Prestige One was to create a speaker with a combination of
visual timeless design and the ability to make you just listen to music and not to
the technical solutions involved.
Where others show off their technical solutions, we try to hide them and just
present a piece of musical furniture that can be nicely placed in your living room.
All the technical solutions are present, but the only role for them is to recreate
the recorded music from your source.We must not forget, that the purpose of a
speaker is to recall an original sound event, making it live again and providing the
same emotions we feel when listening to a big orchestra, a string quartet, a rock
band, a jazz trio or just a vocal with a piano.
This is why Qln thinks of speakers as musical instruments.We know that good
sound depends on the acoustic chamber - just like in a string instrument. But op-
posite to music instruments we don’t create sound, we just reproduce it.
Qln has always searched for cabinet shapes and proportions that will guarantee
exceptional control of internal resonance, perfect acoustics, excellent driver
stability, phase response and easy integration in rooms.
As always, here at Qln the total functional design is the result of the demands for
the resulting sound.

TECHNOLOGY
Qln Prestige One is designed using all the know-how we at Qln have acquired
from producing highly prestigious speakers since 1979, combined with cutting edge
measurements and long critical listening sessions.The speakers are assembled
in Gothenburg, Sweden, the cabinets are made by skilled artisans with careful
selection of the materials used and with strict checks carried out during the work
in progress.This is a guarantee for speaker excellence and inalterability over time.
All the components are carefully selected, the drivers are made by Scan-Speak to
our specications, crossover components and terminal post are from Germany
and are made with great care using high quality components and maximum atten-
tion to the signal route.
1. Unpacking and maintenance
Your speaker should be treated with the same care as you would treat a piece
of furniture. Use 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 the treble
dome since this may leave a mark or damage the dome and spoil its performance.
After unpacking, we suggest you retain all packing material for future transports.
2. Break-in
As with all high-quality loudspeaker systems, the musical performance of your Qln
loudspeakers will improve over an initial break-in period.
Please allow your new speakers to play a minimum 50 hours of music at normal
listening levels before doing any critical listening. Up to 200-300 hours break-in
will be needed for the speaker to reach it’s fully potential of great sound.
3. Stability
Use a stable speaker stand, if possible apply damping material if the stand allows.
Damping the stands is normally a substantial improvement of the sound. Stands
are often delivered with four spikes for acoustical isolation and height adjustment.
To obtain proper mechanical coupling to the oor, adjust until all four spikes have
equal contact. In some cases, if you have a very soft or weak oor, it can be better
to de-couple the speaker from the oor by soft damping pads between the speak-
er and the stand.

4. Room positioning
The performance of a loudspeaker system in a room varies with placement. Ideal
positioning of the speakers is 3-4 m apart and preferably at least 0.5-1m away
from side and rear walls.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
minimise effects of room related resonances.
The longer distance from the back wall, the deeper stereo image you will get.You
can also place some damping or diffusing material on the back wall behind the
speaker, which can help you to get a deeper stereo image.
It’s important that the distance form the listener to each speaker is equal. Differ-
ences as small as 1 cm can make difference. Use a small rope or laser meter to set
the distance as equal as possible.
Choose a stand height so that you barely notice the top area of the speaker when
sitting.Then the treble unit will be at the same height as your ears.You will per-
ceive the most accurate sound stage 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 often will over emphasise
the lower frequencies. Image stability and stereo perception is increased if the two
speakers are turned slightly towards the listening position. Start where you just
can see around two cm of the inside wall of the speaker. Close to this is normally
the best. More toe in will make the stereo image and centre voices more narrow.
The other way the voices will be wider. Try to nd a position where you get a
wide and even stereo perspective from left to right.Then try for best stereo im-
age 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 nal arrange-
ment.And for serious listening - remove the front grill.
We recommend a listening room from 15-50m2, but the speaker can also preform
excellent in even larger rooms. Happy listening!
5. Connections
We recommend the use of heavy gauge loudspeaker cables of high quality. Make
sure to turn off all ampliers before connecting your new speaker to your Hi-Fi
system.
Connect the cable to the terminal. Use the marking of the cable to ensure that
the red or ”+” mark of the amplier is connected to the ”+” side of the terminal,
also marked with red. Often there also is a direction mark on the speaker cable.
It can fx. be an arrow or a text pointing in direction to the speaker.
6. Power handling
Qln recommend using ampliers within a specic power range, see under speci-
cations. However, more important is that the amplier has sufcient power re-
serves for handling of the peaks and transients in the music signal.
The power-rating gure of a loudspeaker is a very imprecise gure. Since the en-
ergy in the music signal varies, neither peak nor average value is relevant.A power
rating of fx. 100W RMS only says that you can play a continuous tone of 1kHz
at this output. It does’nt mean that you can turn the volume all the way up on a
100W amplier and expect a clear sound and healthy speakers.
The greatest danger to a loudspeaker is a distorted signal. Distortion 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 amplier can play
louder without distortion, we have the paradox that it is a greater risk to damage
speakers by playing loud with a smaller amplier.
Caution!
If you hear distortion when you increase the volume this is normally a sign of
overloading the amplier and you should immediately reduce the output level.
Use of loudness, bass or treble boost increases the risk for harmful distortion
in the amplier. We recommend that you use such controls with care or by-pass
them if possible.
7. Service
Should your Qln loudspeaker system require service, or if you have difculty in
achieving the ne performance of which your Qln loudspeaker system is capable,

knowledge required to provide expert advice and assistance. In case the Qln deal-
er is unable to assist you, you are welcome to contact us at Qln direct by email.
[email protected]. You also nd contact info at our homepage, www.qln.se. Regrettably
we can not give direct telephone support to end users.
