Installation

The Chorus 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 (fig. A). 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 Chorus 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. B). 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.
New construction:
• Use the dedicated mounting kit.
• Route the connection cables before installing the plasterboard.
• Ensure that the speakers are con-nected before installing them into 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 a cross-head screwdriver (fig. C, D, E).
Wall Boost Control
Your loudspeakers use an exclusive filtering process known as OPC (Optimum Phase Crossover) guaran-teeing a perfect
stereo image and outstanding sound definition. Ad-ditionally, in order to reduce the "wall effect" inherent to any built
in speaker, we have developed a wall boost equalization circuit which corrects this phenomenon and makes it easier to
position your speakers to suit your preferences.
