POSITIONING
Speakers positioning
Our speakers have been designed to function in a vertical posi-
tion. The majority of our models are delivered with a set of
decoupling spikes or cones, these accessories are to be screwed
in the inserts under the cabinets. These accessories ensure the
stability of the speaker while limiting resonance coming from
certain types of grounds like wood floors.
Powerful drivers generate magnetic fields that can extend
beyond the boundaries of the speaker cabinet. We recom-
mend you keep magnetically sensitive articles (TV, computer
screen, computer discs, audio and video tapes, swipe cards...)
at least 1.5 ft (50 cm) away from the speaker. Cabasse centre
speakers or the ones marked «TV» are not concerned with
this, being magnetically shielded.
Positioning speakers in a room
Optimal positioning for a 2.1
or stereo with a subwoofer system
For a stereo listening with 2 speakers or 2 satellites and 1 sub-
woofer, we recommend you to place the subwoofer in the
front listening area. The placement of the subwoofer against
a wall reinforces the low frequencies and limit the reflections
from 80 to 200 Hz. However to obtain the best results, it is
always necessary to carry out tests according to the acoustic
of the room.
Optimal positioning for a 5.1
or home theatre system
Setting up a multi-channel Audio-Video system requires great
care when positioning the specific AV speakers.
■
The centre speaker should be placed as close as possible to
the screen and where it sounds best from your listening spot
while offering the optimal picture/dialogues cohesion. Theo-
retically, the screen should be located within a virtual triangle
formed by the acoustical centres of the main speakers and the
centre speaker. Practically speaking, this means that the prin-
cipal speaker should be placed above the screen if the main
speakers are below it, and below the screen if the main spea-
kers are above. The centre speaker should also, if possible, be
set slightly back from the others, so that it is located at the same
distance from the listener as the main speakers.
■
The rear speakers or surround should be placed against the
side walls, at listening height. They should not be positioned
far behind the listening zone.
■
The subwoofer should be placed in the front listening area,
its position against a wall reinforces the extreme low register and
limits the reflections between 80 and 200 Hz. However to
obtain the best result, it is always necessary to carry out tests
according to the acoustics of the room.
Your AV processor enables the adjustment in level and delay of
each of the 5/6/7 channels of your system. Fine-tuning is neces-
sary to obtain a perfect sound stage.
Turn off all the amplifiers before interconnecting them to the
loudspeakers. In order to connect loudspeakers properly, it is
most important to keep in mind the following two factors:
cable section and phase.
CONNECTION
Cable section
To get the full sonic
potential of Cabasse
loudspeaker s and
avoid power losses,
the cables connecting
the speakers to the
power amplifier must
have the lowest possible electrical resistance. To help you in
choosing the correct cable gauge, follow diagram.
Phase
In order to maintain the phase relationship and frequency balan-
ce of the loudspeaker system, both loudspeakers must be pro-
perly connected to the power amplifier. When properly connec-
ted, the cones of the drivers of both loudspeakers will move in
the same direction when driven by identical speakers will move
in the same signals. If the cones move in opposite directions, the
resulting out of phase signals will create a perceptible power
loss, particularly in the low frequencies. The stereophonic mes-
sage will also be degraded. Amplifier and speaker manufacturers
typically indicate connection polarity in one of two ways: red
and black or plus and minus. In either case, always connect red
or plus to red or plus and black or minus to black or minus.
Connections should be identical for both channels. To check
that the speakers are in correct phase, switch the system to
mono while music is being played. if the amplifier does not have
a phase inversion switch, it will be necessary to change over the
connections on one only of the
loudspeakers. If in correct phase,
the image should be distinctly loca-
ted between the loudspeakers with
a slight loss of bass and low
midrange level. If the image is
confused and not centrally loca-
ted and there is a drastic loss of
bass and low midrange level,
recheck your connections.
2 possibilities are offered to connect the subwoofer with your sys-
tem:
■
the low level one requiring the use of the CINCH RCA LINE IN
7
and LINE OUT
6
terminals and shielded coaxial connec-
tors,
■
the high level one requiring the use of the speaker HI LEVEL
INPUT
5
and HI LEVEL OUTPUT
4
terminals, and standard
loudspeaker cables.
The inputs are stereo ones, the mix of the L (left) and R (right)
low frequencies being done by the amplifier of the subwoofer.
If the input signal is already mono, only one input L (left) or R
(right) should be used.

Attention,
before operating the unit,
be sure that the
operating voltage
of your unit is identical
with that of your local
power voltage.
