Focal ELECTRA IW 1000 Be Notice page 3

Installation
The Electra input sockets ensure
reliable multipurpose connections
for stripped cables as well as for
plugs. It is imperative to respect
the connector polarity of both the
loudspeaker and amplifier. The
positive terminal "+" must be
connected to the corresponding
(matching) amplifier's terminal
and the negative terminal "-" to the
negative terminal. Stereo image,
soundstaging and bass perception
would be seriously compromised
if these conditions were not
respected. Don't underestimate
the importance of the cable: make
sure you chose the appropriate
section and length. Let your retailer
advise you.
About amplifiers
Contrary to what one might think,
it is not a too powerful amplifier
that might damage a loudspeaker,
but rather a lack of power.
Actually if the output level of the
amplifier is too high it will saturate
and distort which will irremediably
damage the tweeter. The power
handling and frequency response
of the Electra loudspeakers is good
enough to highlight the qualities
or weak points of the amplifiers
they are combined with. Let your
retailer help you make the right
choice, matching your personal
taste and budget.
Mounting
This should be carried out after all
of the cables have been fitted. We
recommend that you use a marked
cable in order to conserve the
polarity of the speakers (+/-).
Existing construction:
• Cut the dry wall using the
template supplied (fig. A). Be
sure to check that this is perfectly
vertical using a spirit level before
you begin cutting.
• Check construction plans of
your room to make sure that
you are not drilling into a pipe,
an electrical cable or any other
specialised installations behind
the wall.
Fixing
The loudspeaker is firmly fixed into
the wall using a system of clamps.
To achieve this, place the speaker
into the cut-out and tighten
the fixing screws in a clockwise
direction using the hexagonal key
(fig. B, C, D).
Wall Boost Control
Your loudspeakers use an exclusive
filtering process known as OPC
(Optimum Phase
guaranteeing a perfect stereo
image and outstanding sound
definition. Additionally, in order
to reduce the "wall effect" inherent
to any built in speaker, we have
developed a wall boost equalization
circuit which corrects
phenomenon and makes it easier
to position your speakers to suit
your preferences (fig. E).
