Cabasse SANTORIN 21 - Manual (Page 7)

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 decou-
pling 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 recommend 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 mar-
ked «TV» are not concerned with this, being magnetically shiel-
ded.
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 neces-
sary 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 whi-
le offering the optimal picture/dialogues cohesion. Theoretical-
ly, 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 principal spea-
ker should be placed above the screen if the main speakers are
below it, and below the screen if the main speakers 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 lis-
tener 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.
