INTRODUCTION
Welcome to the exclusive circle of Jamo R 907 owners! This manual will give you a
quick overview of how to set up your speakers in your room.For more in-depth in-
formation about the technologies please refer to the R 907 technical description.
The first word of advice. After setting up your R 907s for the first time, please allow
yourself a couple of days to listen to them before you start fine-tuning the sound.
This will serve two purposes. Firstly, you will get a sense of what these speakers
sound like. Secondly, it will give time for the speakers to run in: the tonal quality of
this design changes slightly after the first couple days of playing music.
Please remember the guidelines in this manual are only recommendations. There
are no hard and fast rules about setting up a pair of speakers as unique as these.
When you get down to fine-tuning their performance in your room don’t be afraid
of experimenting: any speaker will sound different when moved a few inches. Feel
free to change the speakers’ positions and move them around the room to deter-
mine your best listening position and sound.
Always rely on your own judgement to determine what sounds best.We do...
Enjoy!

PLACEMENT
As a starting point, we suggest you initially position the R 907s 3 feet from the back
wall and 4 feet from the side wall.
Angling the speakers 10 degrees to the back wall will reflect the generated sound
off your back and side walls,which will give you the acoustic impression of a much
larger room.
Also remember that a dipole speaker emits virtually no sound from the side. You
can take advantage of this trait to cancel reflections from the side wall by varying
the toe-in angle.

LISTENING POSITION
To find the best listening position, place yourself at a 30 degree angle from each
speaker. Doing so means that you will be seated at about the same distance away
from the speakers as the actual gap between them. The benefit of this is that the
direct radiating sounds from each speaker will cross each other at a point behind
you.
IF YOUR ROOM…
a) doesn’t allow you to get the speakers the required distance from the back
and side walls or…
b) has highly reflective surfaces (ie. glass windows or bare plastered walls)
or…
c) still doesn’t sound quite right
…we strongly recommend that you damp your room’s critical surfaces.This can be
done by the simple expedient of adding curtains, furniture,bookshelves and so on.
A damped surface is almost always preferable to a hard reflective surface.

SPIKES
After the initial placement of the speakers it’s now time to screw in the spikes. Be-
cause of the weight of the R 907, we recommend that you gently lay it on one side
and screw in all four spikes together. Before you do this, however, be sure to place
a couple of thick towels or similar underneath the side of the speaker.This will pre-
vent accidental scratching to the surface of the R 907 and,equally importantly, will
avoid you putting a rather large dent in your floor.
After screwing in the spikes,we recommend you fit them with the hard rubber feet
and the indented metal washers we’ve supplied. These will spare the floor from
damage and allow you to gently bring the speaker to its vertical position. Once
upright simply adjust the spikes to give optimal support.
Floor surfaces vary considerably so we have given you 3 different choices when it
comes to spiking options.You can keep the hard rubber feet on the spikes, rest the
spikes on the four indented metal washers, or place the spikes directly onto the
floor. Always choose the option that gives the most stability for your speakers in
your domestic environment.
Using the spikes without the hard rubber feet or indented metal washers will give
the very best support and sound quality. If you want to spare your floor surface
from being punctured however, the rubber feet or indented metal washers are a
good compromise.Sonically, there’s really very little difference between them - use
whichever one suits your floor surface better.
A warning:be careful when using the spikes with the indented metal washers - you
don’t want to get your finger trapped between the two!
Whichever spiking option you choose, avoid“walking” the speakers if you need to
move them to a different position… especially on hard wood floors!

CONNECTING
SINGLE-WIRING
For single-wire connections, the terminal jumpers should be attached as shown in
the illustration.
BI-WIRING
If you’d like to use a bi-wiring arrangement, make sure you remove all the terminal
jumpers before you connect up your loudspeaker cables.
BI-AMPING
In a bi-amped system, make sure you remove the terminal jumpers before con-
necting up your cables. The top pair of terminals drive the tweeter while the pair
underneath drive the bass and midrange units.
If you choose this option, we recommend you use identical amplifiers for both ter-
minals.

FRONT AND BACK FABRIC COVERS
The front fabric covers have been designed to have minimal influence on the sound
quality. However, for critical listening we would advocate that you remove them.
The rear fabric covers have no influence on the sound quality. It’s entirely up to you
and your aesthetic preference whether you have them on or not.
When removing and putting on the front and back cov-
ers,however,make sure you do so gently,in order to pre-
vent scratching or marking.
We recommend placing your hands level with the two
top hooks on the front cover when lifting it, for optimal
balance.
We recommend placing your hands level with the two top hooks on the front cover

Please note that the front fabric cover, like the speaker itself, isn’t of conventional
design.When putting the cover on, make sure all four metal hooks on its frame are
resting securely on all four screws. If not placed correctly, it could fall off and per-
haps even be damaged.
If you choose to remove the front cover for longer periods of time, the four screws
onto which you mount the cover can be unscrewed, for a more attractive aesthetic
appearance.

CLEANING
Please use a dust-free cloth to clean the R 907. It is also possible to use a slightly
damp cloth for more stubborn marks.
Under no circumstances should you use any kind of cleaning agent on, or in close
proximity to, these speakers.

INTRODUCTION
Bienvenue dans le cercle exclusif des possesseurs de Jamo R 907!
Ce mode d’emploi vous fournit quelques conseils sur l’installation des enceintes
dans votre pièce d’écoute.Pour une information plus détaillée sur les technologies
utilisées,veuillez consulter le cahier technique des R 907.
Notre premier conseil : une fois les enceintes R 907 positionnées dans votre pièce
d’écoute,et avant de commencer le paramétrage acoustique,apprivoisez le son des
enceintes en les écoutant sur 2 ou 3 jours.Cette manipulation comporte deux avan-
tages. Premièrement, vous allez pouvoir ressentir la sonorité des enceintes. Deux-
ièmement, vous allez roder les haut-parleurs. En effet, la qualité tonale de ce type
de produit change légèrement après les deux premiers jours de fonctionnement.
Les conseils de ce mode d’emploi sont seulement des recommandations. Il n’y a
pas de règles strictes et précises pour installer une paire d’enceintes aussi unique
soit-elle ! Lorsque vous en arrivez aux paramétrages de leur performance dans la
pièce d’écoute, n’ayez pas peur d’expérimenter :une enceinte sonne différemment
si vous la déplacez de seulement quelques centimètres. Déplacez vos enceintes
dans la pièce afin de trouver la meilleure position d’écoute et le meilleur son !
Faites toujours confiance à vos impressions et à votre jugement pour déterminer ce
qui sonne bien ! C’est ce que nous faisons.
Bonne écoute !

POSITIONNEMENT
Pour commencer, nous vous suggérons de placer les R 907 à 90 cm (3ft) du mur
situé derrière les enceintes et à 1m20 (4ft) des murs latéraux.
Tournez chaque enceinte pour former un angle à 10 degrés par rapport au mur
situé derrière l’enceinte afin de réfléchir le son sur les murs avant et latéraux pour
avoir l’impression acoustique d’une pièce beaucoup plus grande.
Enceinte dipolaire, R 907 émet des ondes sonores vers l’avant et vers l’arrière de
sa façade. Elle n’émet aucun son sur les côtés. Vous pouvez utiliser cette carac-
téristique pour annuler les réflexions des murs latéraux en changeant l’angle de
l’enceinte par rapport au mur.

POSITION D’ÉCOUTE
Pour trouver la meilleure position d’écoute, placez-vous dans un angle à 30 degrés
de chaque enceinte. A cet emplacement, vous serez assis à la même distance des
enceintes que la distance qui les sépare. L’avantage : les ondes sonores directes de
chaque enceinte vont se croiser juste derrière vous.
SI VOTRE PIÈCE D’ÉCOUTE :
a) ne vous permet pas de placer les enceintes aux distances nécessaires par
rapport aux murs, ou…
b) comporte des surfaces extrêmement réfléchissantes (baie vitrée, fenêtres
ou murs nus en plâtre), ou…
c) ne sonne pas très bien,
nous vous recommandons de traiter votre pièce d’écoute avec des panneaux
acoustiques.Vous pouvez aussi simplement installer des rideaux,des meubles,une
bibliothèque, etc. Une pièce amortie est vraiment plus agréable qu’une pièce aux
surfaces réfléchissantes.
