Aluminum/magnesium alloy TNA inverted dome tweeter

the tweeter of the Chorus V benefits from the inverted dome technology, which is exclusive to Focal-JMlab. It allows optimal energy transfer and wide dispersion. The aluminum/ magnesium alloy making up of the dome guarantees exceptional performances in terms of stiffness and damping thus ensuring a subtle blend of softness and dynamics.

Polyglass bass:

impregnated paper cones with a fine layer of silica micro-balls for a fully dynamic bass impact, precise and distortion-free.

OPC

phase optimization for a precise, natural and stable soundstage and image.

Wall Boost Control:

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.

Adjustable aluminum inverted dome tweeter:

detailed and non directive.

Easy integration:

the aluminum grille and reinforced ABS chassis can be painted.

Optional mounting kit Design to work in wet environment:

In kitchen, bathroom… Ideal for installations in yachts.

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 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 (fig. 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.

Installation

Speakers placement

The Chorus V loudspeakers have been engineered to deliver the most faithful sound reproduction, whether they are used for music or home cinema. In order to enhance their performance, to guarantee a high quality of listening, sound image and tone balance, it is important to note the following basic rules. The listening area must be located at the summit of an equilateral triangle whose two other points of insertion are determined by the position of each speaker. Nevertheless it is possible to modify these distances to find an ideal compromise according to the particular disposition of the room (fig. F). Each loudspeaker must be placed at the same height and on the same floor plan. The tweeter should be at the same height as the listener’s ear, when the listener is in his usual listening area (fig. G).

Surround and center speakers placement

The soundtrack mix for a film or music encoded in multichannel format is very complex and allows the listener to benefit from a wide range of special sound effects, which require the use of effect channel speakers. In order to obtain a realistic 3D soundstage, the placement of the speakers is decisive, even when confronted with a restrictive disposition of the listening room. For enhanced performances, the following elements should be noted. Central channel speakers should be placed close to the TVscreen to obtain a proper placement and a realistic reproduction of the dialog (fig. Ha). They could be placed below or above the TV-screen if your TV-unit permits. If a standart projection screen is used, the central channel speaker must be placed under the screen. If an acoustically transparent projection screen is used, the central channel speaker can be placed behind and at the bottom of the screen. Avoid placing the effect speakers too far from the listening area otherwise the sound perception will be altered. In order to obtain surround effects, with great sound density we advise you to place the speakers against the sidewalls on each side of the listening room (fig. Hb, Hd). You can use IC 706 V as In Ceiling surround speakers (fig. Hc) or for back center surround channel for

6.1 or 7.1 configuration.

Adjustment of tweeter

To carry out adjustments, use the switch level located on the front baffle of the speaker as follows (fig. I). Adjust the tweeter facing the listening area (fig.J).

Paint

If you wish, you can paint your speaker to match your room. We advise that you paint the grille and the housing of the speaker separately. For the frame: remove the grille and place the paint mask in position to protect the drivers. For the grille: if necessary remove the driver mask from the grille before painting. You can put this mask back into position after drying if you wish.

Cautions

Precautions

As the loudspeaker’s covering materials are strong, scratch- and stain-resistant, maintenance is easy and consists only in cleaning the covering with a dry cloth. If the enclosure is stained, we simply recommend the use of a damp cloth. Never use any solvents, detergents, alcohol or corrosive products, scrappers or scouring powder to clean the surface of the loudspeaker. Avoid placing the loudspeakers near a heat source.

Running-in period

The drivers used in the Chorus V loudspeaker are complex mechanical devices and require a run-in period before they deliver their best performance. They must get adapted to the temperature and humidity conditions of their environment. This breaking-in period depends on the encountered conditions and can last several weeks. In order to shorten this period, we advise you to let your loudspeakers operate for about twenty hours at medium level, playing standard musical programmes, but with a large amount of bass. Once the components of the loudspeakers are completely stabilized, it is possible to enjoy the real performance of your Chorus V loudspeakers.

Magnetic disturbance

In home theater systems, the magnetic radiation of the loudspeakers must be taken into consideration. These loudspeakers generate a magnetic leak that can interfere with household appliances, some of which are sensitive to this phenomenon. It is strongly advised not to place front loudspeakers closer than 50cm to your TV screen. Frame geometry as well as colours can be severely distorted by a magnetic field if the loudspeaker is placed to close to the TV.

Conditions of guarantee

All Focal-JMlab loudspeakers are covered by guarantee drawn up by the official Focal-JMlab distributor in your country. Your distributor can provide all details concerning the conditions of guarantee. Guarantee cover extends at least to that granted by the legal guarantee in force in the country where the original purchase invoice was issued.
