CHORA
U s e r m a n u a l
In general, aim to have a reflective wall behind the loudspeakers so that the sound develops correctly.
The wall behind the listening area, meanwhile, will ideally be absorbent to prevent rear reflections from
"contaminating" the perception of the stereo image. Furniture can be placed judiciously on the side walls
to diffuse the sound waves and therefore ensure certain frequency ranges are not excited, particularly in
the midrange (suppression of flutter echoes).
Positioning the Chora Center (fig. D, E)
The central loudspeaker should be placed close to the screen for realistic dialogue reproduction. It can be
placed beneath the television if the TV unit allows this.
If a standard projection screen is used, the central loudspeaker must be placed below the screen for
optimum results. (fig. D)
If a micro-perforated screen is used, it can then be placed behind and towards the lower half of the screen.
If positioning the loudspeaker on a furniture unit, make sure you stick on the silicone feet before installation.
You can also add the rubber base beneath the loudspeaker, in the space provided, to tilt the loudspeaker
backwards and thereby slightly lift the soundstage. (fig. E)
Positioning of Chora Surround loudspeakers (fig. F)
The complexity of today's film soundtracks, particularly those mixed in 5.1 or 7.1, allows a very broad
diversity of surround effects to be achieved. The choice of where to position the Surround loudspeakers is
therefore a deciding factor in achieving a realistic three-dimensional space.
The aim is to achieve sounds that are sufficiently diffused and difficult to locate by applying some basic
rules.
Avoid placing the Surround loudspeakers too far back in the listening area, as the perception will be
compromised. Opt for a position on the side walls to obtain the most enveloping sound effects.
- Sit in your listening position
- Refer to the positioning diagram (fig. F). It gives you the best position for your 5.1 and 7.1 loudspeakers.
Fixing the Chora Surround to the wall (fig. G, H)
- Stick the feet onto the back of the loudspeaker in the spaces provided.
- Position then fix the wall bracket onto the partition. The height at which the screws will be fixed
corresponds to the height of the tweeter. Screws and wall plugs are not supplied. Only use wall plugs
suitable for the nature of your partition.
- Connect the cables to the loudspeaker before hanging it on the wall.
- Hold the loudspeaker in front of the wall bracket. Attach the loudspeaker firmly to the bracket by applying
pressure to the top of it.
Break-in period
The speaker drivers used in Chora loudspeakers are complex mechanical components which require a
certain time to adapt to operate at their best and to become acclimatised to the temperature and humidity
of the listening environment. This break-in period varies depending on the climate and may last a few
weeks. To reduce the break-in period, we recommend operating the loudspeakers for approximately
twenty consecutive hours. Once the loudspeakers' characteristics have totally stabilised, you will be able
to enjoy your Chora loudspeakers' performance to the full.
