GRILLES
It is essential that the SuperTweeter
™
diaphragms are not touched, any damage will destroy performance
and require specialist repair by your Tannoy dealer. Any such damage will not be covered under
warranty.
The main Eyris DC 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.
WARNING:
PROTECTIVE TWEETER GRILLES ARE SUPPLIED FITTED TO THE SUPERTWEETER
™
HOUSING.
THEY ARE HELD IN PLACE BY MAGNETISM, SO, IF THEY DO REQUIRE REMOVAL AND
REPLACEMENT PLEASE DO SO EXTREMELY CAREFULLY - NO PRESSURE NEED BE APPLIED
ON REFITTING. TRANSIT PROTECTION CARD SHOULD BE REMOVED DURING INSTALLATION.
CARE OF CABINET
The cabinets should only be cleaned with a dry cloth or with a light application of quality non-silicone
furniture polish.
EYRIS DC 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.8)
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.
Total design compatibility, ensuring all models share the same acoustical balance and dispersion
characteristics, means that it is essential that an Eyris DC A/V system is built around only Eyris DC Dual
Concentric
™
models (it is not possible to mix in products with other driver types) as the acoustic
integration of each has been optimised only for use as a complete system.
In Home Theatre applications this acoustic benefit 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.
SCREENING
The large magnet assemblies on the loudspeaker drive units of all Eyris DC models are fully screened
to eliminate colour-fringing effects when mounted close to television monitors.
FRONT SPEAKERS
The ultra wide dynamic range and power handling capability of Eyris DC 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
The Eyris DCC centre channel speaker is fully magnetically shielded and designed for installation
directly above or below the TV. As the main effects speaker for the front soundstage, the critical factor
in its performance is the placement. 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 Eyris DCC 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.
WARNING:
ENSURE THAT THE CHOSEN SUPPORT PLATFORM IS STRONG AND STABLE ENOUGH TO TAKE
THE WEIGHT OF THE EYRIS DCC. IT IS NOT RECOMMENDED THAT SPEAKER BE BALANCED
ON TOP OF THE TV OR PLASMA SCREEN.
REAR EFFECTS SPEAKERS
The integrity of the special effects soundstage created by the source material will be compromised if
the speakers are installed on the sidewalls, for that reason they should always be placed behind the
main viewing position.
The placement of floor standing (Eyris DC3) or stand mounted (DC1) speakers at the rear should mirror
as near as possible the location of the front pair and 0.5 metres (20 inches) from the rear wall. Wall-
mounted loudspeakers (DC1 fitted with OmniMount
™
style brackets) should be mounted 1.5 to 4.5
metres (5ft to 15ft) apart with a height mounting height range of 1.5 to 2 metres (5ft to 7ft). Alternatively
the DC1's may be shelf mounted although this may present positional compromises that affect ultimate
performance.
WARNING:
FOR WALL MOUNTING INSTRUCTIONS SEE PAGE 5 AND FIG. 9, WHILST ALSO REFERRING TO
THE MANUAL PROVIDED WITH YOUR CHOSEN OMNIMOUNT
™
STYLE BRACKET.
SUBWOOFER
As the subwoofer only produces low frequency, therefore monaural information, it is difficult to detect
its location by ear. It could as a result be situated anywhere in the room, but optimum performance
will be gained by locating the subwoofer between the main stereo pair of speakers. Bass output will
increase when placed next to a wall or in a corner so use the subwoofer volume control to balance
the output with the rest of the system.
Please refer to the manual supplied with the subwoofer for advice on installation and set-up.
