Optimal positioning for a 2.0 or stereo system
(page 6)
For the ideal positioning of your speakers follow diagram A. If
«d» is the distance between the two speakers, this distance must
be higher than 5 ft (1.5 m) and the two speakers must be at equal
distance from the listening area which forms with them an equi-
lateral triangle.
The drivers must be directed towards the listening area.
The speakers should be located so that their diffusion follows
the longest dimension of the room.
Generally speaking it is better to avoid putting the speakers in
the corners of a room as this amplifies the low frequencies and
tends to enhance the room resonances. If possible it is better to
place the speakers at least 8 inches (20 cm) from the walls.
To ensure a sufficient ventilation of the electronic components
of the active loudspeakers, always leave 10 cm or more free space
between the rear of the cabinet and any wall, mobile partition,
piece of furniture, curtain or cloth.
No solid object or piece of furniture should be placed between
the speakers and the listener. An effect of such a mask, even par-
tial, disturbs completely the sound reproduction as it attenuates
the high frequencies and also, in most cases, the midrange fre-
quencies.
Placing these active loudspeakers in niches is prohibited. It
alters the frequency response of the speaker and prevents proper
ventilation of the electronics.
SPEAKER-DAP PREAMPLIFIER CONNECTION
(page 4)
Connect both optical cables (the ones delivered with the system or
equivalent models with the required lengths) to the b2 «Speaker
OUT» terminals of the DAP and to the a2 «OPT In» sockets of the
loudspeakers.
a3 ASSIGN switch settings: select Right for the loudspeaker at your
right when facing the speakers and Left for the speaker on the left..
Check on both loudspeakers that the a4 switch is pressed «on» to
activate the illumination of the logos in front of the cabinet when
the system is in use.
UNPACKING (page 2 & 3)
The system is delivered in 3 packages:
2 x crates for the active loudspeakers
1 x cardboard box for the DAP (Digital Adaptive Preamplifier),
the remote control, 2 AAA batteries, 6 cones, 1 hex key for the
release of the castors, 1 rod for the adjustment of the cones, 2
class I power cables, 1 class II power cable, two 10 m optical
cables, 1 measurement microphone and base, 1 owner’s manual,
1 warranty card, 1 pair of gloves and a micro-fiber cloth.
Speakers unpacking: follow carefully the steps detailed on
pages 2 and 3, then assemble the parts of each empty packing
including all the packing accessories and store the crates in a dry
place for future use.
Cardboard box unpacking: after removing the top carton
flaps, fold them right back and remove the accessories and the
foam sheet to reach the preamplifier packing. Check that none
of the above listed accessories are missing.
The packing must be retained at least during the validity period
of the warranty.
POSITIONING
Speakers positioning
The L’Océan loudspeakers are delivered with a set of decoupling
cones (page 4). These accessories are to be screwed in the inserts
on the base of the speakers, after having removed the castors with
the help of the hex key. Adjust the height of the cones by using
the rod also delivered with the speakers. These accessories ensure
the stability of the speaker while limiting resonance coming from
certain types of flooring such as wooden floors.
Speakers are delivered with a front grille to protect drivers. It is
possible to use them without this front grille, by gently pulling its
top end in order to cut off its magnetic link with the magnets to
the front panel. To get the grill back in place, position it in front
of the speaker and approach it to the front panel until the ma-
gnetic link is effective. These operations must be carried out very
smoothly in order not to damage the veneer covering the magnets
on the front panel of the speaker .
Powerful drivers generate magnetic fields that can extend beyond
the boundaries of the speaker cabinet. We recommend you keep
magnetically sensitive articles (CRT TVs and computer monitors,
computer discs, audio and video tapes, swipe cards...) at least
1.5 ft (50 cm) away from the speaker.
Positioning speakers in a room
In addition to the vertical position of the speakers themselves,
their location in the listening room, as well as the acoustical cha-
racteristics of the room, are also very important. As it is impos-
sible to indicate a typical location of speaker systems without a
few tests, we suggest several general rules that are important to
apply in order to obtain the best listening results.
L’OCÉAN SYSTEM
These speakers are very heavy, so 2 persons minimum are requi-
red to unpack and re-pack them.
ATTENTION : the L’Océan loudspeakers must be used
with either the cones or the castors to ensure the right air cooling
for the built-in electronics. Any use without it will invalid any
warranty claim.
ATTENTION : Before operating the unit,be sure that the
operating voltage of your unit is identical with that indicated
on packing, the warranty card or the sticker on the base of the
speaker. If not, please follow the instructions of the POWER
SUPPLY section.
ATTENTION : To prevent any alteration of the signal
transmission through the optical cables, never roll up the cable
tightly. The diameter of the loops must be at least ten times bigger
than the thickness of the cable itself. Keep the ends of the bare
optical cable very clean. If necessary, clean them with isopropyl
alcohol.
