GRILLES
The Precision grille has been designed to provide acoustic transparency. However, for ultimate fidelity the
enthusiast will appreciate the slight improvement in clarity and detail that is achieved by removing the grilles during
listening. It is held in place by concealed magnets, to promote a neat visual appearance when removed.
CARE OF CABINET
The cabinets should only be cleaned with a dry cloth or with a light application of quality non-silicone furniture polish.
PRECISION HOME THEATRE 5.1 - GENERAL INFORMATION
Unlike other forms of encoded surround audio, 5.1 offers full bandwidth capability for the surround and centre
channels, with the ability to treat the subwoofer as a single discreet channel for special effects playback or, for
music applications, as a dedicated low frequency instrument channel. This places new demands on the surround
and centre channel loudspeakers in both the mixing environment and the playback environment.
The 5.1 format allows the mix engineer in the recording studio to assign audio information to one or more discreet
channels of playback; providing very vivid and exacting localisation for the apparent sound sources in the
listening environment. To reliably recreate that accurate localisation during playback, the selection and location of
loudspeakers becomes the single most critical issue next to the talent of the mix engineer in the studio. (See Fig. 6)
THE SYSTEM
A fully operational 5.1 system consists of two main front loudspeakers, two rear effects speakers at the rear
(usually wall mounted) and a centre channel. The subwoofer provides the .1 part of the system.
In home Theatre applications the matched dispersion of all Precision models provides a very focussed soundstage
retaining natural voicing and ensuring that aural effects and speech localisation ‘pan’ from left to right and front to
rear seamlessly.
WARNING, STRONG MAGNETIC FIELDS
The powerful magnet system in Revolution XT models will cause picture distortion with conventional CRT
televisions and monitors, and should not be used in close proximity. There are no issues with plasma,
LCD or LED televisions or monitors.
FRONT SPEAKERS
The ultra wide dynamic range and power handling capability of Precision loudspeakers will provide a stunning
home cinema experience. The speakers should be positioned on either side of the TV or projection screen and
then placed in line with the screen surface.
CENTRE CHANNEL SPEAKER
In all cases the centre channel speaker should be positioned as near to the TV screen as possible. The viewing
position when seated determines the ideal mounting height, but in all cases this should be as close as possible to ear
height. As with the main speakers the front baffle panel should be as near as possible in line with the screen surface.
The Precision centre channel can be wired in single wire, bi-wire or bi-amp modes. Please refer to figs. 4, 5 & 6 for
connection guidance bearing in mind that connection should be made to the dedicated centre channel output on your
A/V processor amplifier/s. For optimum stability, locate the centre channel on the plinth provided.
Warning:
Ensure that the chosen support platform is strong and stable enough to take the weight of the Precision C.
