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.

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

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

terminals and shielded coaxial connec-

tors,

the high level one requiring the use of the speaker HI LEVEL

and HI LEVEL OUTPUT

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.
