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 (pic. 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 (pic. 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 connected 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 (pic. C, D, E).
Wall Boost Control
Your loudspeakers use an exclusive filtering process known as OPC (Optimum Phase Crossover) 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 this phenomenon and makes
it easier to position your speakers to suit your preferences.
