CABLE CHOICE  
WARNING:  
Always use the best quality of cable available within your budget. High quality audio signals passing  
from the amplifier to the loudspeaker are unusual in their demands on the cable. Wide dynamic range  
and frequency bandwidth information has to coexist with the ability to transmit peak currents of at least  
10amps, without incurring any loss or signal impairment. This explains why the sound quality of the  
information reproduced by the loudspeakers is so dependant on the physical properties of the cables  
connecting them to the amplifier.  
ENSURE THAT THE SPIKES ARE LEVELLED AND THAT THE LOCK NUTS ARE TIGHTENED FIRMLY.  
THE SPIKES SHOULD BE PUSHED THROUGH THE CARPET TO LOCATE INTO THE FLOORING  
SURFACE BY APPLYING PRESSURE TO THE TOP OF THE CABINET.  
IF USING ON A SENSITIVE FLOOR SURFACE PLACE THE PROTECTIVE CUPS UNDER THE LEVELLED  
SPIKES.  
FAILURE TO DO SO COULD RENDER THE SPEAKER UNSTEADY AND RESULT IN DAMAGE OR  
INJURY SHOULD IT BE KNOCKED OVER.  
We would recommend that you always keep the cable runs the same length for each speaker.  
Remember, cable construction can affect the sound quality so be prepared to experiment to find a  
cable that suits your ear and audio system.  
STAND MOUNTING MODELS  
TERMINAL PANEL  
Stand mounting or bookshelf speakers should be located securely on stands or a shelf in an appropriate  
position to place the SuperTweeterhigh frequency unit roughly at ear height when seated in the  
chosen listening position. Positioning recommendations for stand-mounted speakers can be found  
under the section entitled Positioning and fine-tuning.  
An exclusive five way terminal panel has been designed for the Eyris Dual range to optimise performance  
further by take advantage of the driver earthing facility. Use a shielded or screened loudspeaker cable;  
connecting the screening termination to the earth or 'ground' (green) terminal on the loudspeaker and  
to the ground or earth connection on the amplifier. Alternatively if you are not using a screened  
loudspeaker cable but wish to utilise the earthing facility, run a single cable between the earth or  
'ground' (green) terminal on the loudspeaker to the earth (ground) connection on the amplifier.  
(See fig.3)  
WALL MOUNTING REAR CHANNEL SPEAKERS  
The Eyris DC1 has been designed to act either as a stand mount stereo pair or as stand or wall mount  
rear speakers in a multi channel system configured for home cinema applications. The speaker is  
provided with threaded inserts in the rear panels to accommodate the fixing hardware for an OmniMount™  
type speaker wall bracket. This widely available design of bracket allows the speaker to be angled to  
provide the best acoustic performance from the rear soundstage.  
UNPACKING  
To unpack the loudspeakers from their boxes remove tape from the top then fold the flaps right back  
before inverting the carton and contents. Lift the carton clear of the contents then remove all inner  
packaging.  
WARNING:  
IT IS ESSENTIAL TO SELECT THE CORRECT TYPE OF SCREWS AND FIXINGS TO SUIT THE  
CONSTRUCTION MATERIAL OF THE WALL ONTO WHICH THE SPEAKER IS TO BE MOUNTED.  
ENSURE THAT THE OMNIMOUNTHANGING BRACKET IS FIXED TO THE WALL IN A SECURE  
MANNER; FAILURE TO DO SO COULD RESULT IN DAMAGE OR INJURY SHOULD THE SPEAKER  
BECOME DETACHED IN USE.  
It is strongly recommended that you store all the packaging to allow protected transportation in future.  
(See fig.1)  
WARNING:  
WHEN UPACKING THE EYRIS DC MODELS NOTE THAT THE SUPERTWEETER IS MOUNTED IN  
THE EXTRUSION ON TOP OF THE CABINET - TAKE CARE NOT TO TOUCH THE TWEETER DOME  
ITSELF AS IRREPARABLE DAMAGE WILL OCCUR.  
SEEK PROFESSIONAL ADVICE IF YOU ARE UNSURE WHICH WALL FIXING IS BEST SUITED TO  
YOUR PROPOSED MOUNTING LOCATION.  
PROTECTIVE TWEETER GRILLES ARE FACTORY FITTED TO PROTECT THE DELICATE DOME (THEY  
ARE HELD IN PLACE BY MAGNETISM), WITH AN ADDITIONAL CARD RETAINER SECURING THIS  
MESH GRILLE IN PLACE DURING TRANSIT.  
INSTALLATION  
To avoid potential damage to your loudspeaker, ensure that the amplifier is switched OFF prior to  
connecting or disconnecting any cables. Before switching on double check that all connections are  
secure and that polarity is correct.  
PLEASE REMOVE THIS CARD DURING THE INSTALLATION PROCESS.  
FLOOR STANDING MODELS  
The spiked metal feet, designed to extend the footprint of the speakers to aid stability and provide an  
efficient acoustic coupling with the floor, are in an accessory kit packed in the end of the box. To fit  
these, lay the speaker down gently on its back and align a slot in a metal foot to one of the threaded  
inserts located in the base. Insert the bolt supplied, noting the correct positioning of the two washers,  
and tighten firmly while pushing the foot against the sidewall of the cabinet ensuring there is no  
unwanted movement.  
Repeat the process with the remaining three feet.  
Eyris floor-standing models perform best with carpet piercing spikes fitted. These are supplied, along  
with lock nuts, and should be inserted into the threaded holes in the base of the metal feet. Level the  
speaker and then tighten the lock nuts firmly but without using undue force. Spike locating cups are  
provided in the accessory pack and these may be used to protect sensitive floor surfaces. (See fig.2)

CONNECTION IN SINGLE WIRE MODE  
BI-AMPING  
The terminal panels have captive link bars fitted as standard to link the positive and negative HF and  
LF terminals respectively. These must be removed to bi-wire the speakers - see section entitled Connection  
in Bi-wire mode. (See fig. 4)  
Bi-Amping extends the principle of bi-wiring one stage further. In this connection option separate power  
amplifiers are used for bass and treble signals in each loudspeaker. Four mono (or two stereo) amplifiers  
of the same type are required for a stereo pair of loudspeakers. Ensure that the cable links between  
the loudspeaker terminals are removed and that correct polarity is maintained throughout.  
For optimum performance in single wire mode, loudspeaker cable connections from the amplifier  
should be made to the high frequency (HF) terminals of the loudspeaker:  
If two stereo amplifiers are used, it is recommended that one amplifier supply bass information to left  
and right loudspeakers and the other, the treble information. (See fig. 6)  
* The positive (plus) terminal on the amplifier left channel (marked + or coloured red) must be connected  
to the positive HF terminal on the left speaker. The left speaker is the one on the left as you look at  
the stereo pair from your listening position.  
CONNECTION OF EARTH OR 'GROUND' LEAD  
Use of a shielded or screened loudspeaker cable will offer further performance advantages when used  
with the five-way terminal panel. The screening termination should be connected to the earth or ground  
(green) terminal on the loudspeaker and to the ground or earth connection on the amplifier. Alternatively  
if you are not using a screened loudspeaker cable but wish to utilise the earthing facility, run a single  
cable between the earth or 'ground' (green) terminal on the loudspeaker to the earth (ground) connection  
on the amplifier.  
* The negative (minus) terminal on the amplifier left channel (marked - or coloured black) must be  
connected to the negative HF terminal on the left speaker.  
* Repeat this connection process for the right speaker. Remember that the positive (+ or red) on the  
amplifier must be connected to the positive (+ or red) on the speaker and the negative (- or black)  
to negative.  
* Select a signal source, such as a CD player; switch on the amplifier and slowly turn up the volume  
control to check that both loudspeakers are reproducing bass and treble information.  
It is essential that the coupling link cables between the loudspeaker terminals be removed.  
Avoid potential damage to your amplifier - ensure that all connections are secure and the polarity is  
correct in all wiring. (Method illustrated on all terminal panel sketches)  
CONNECTION IN BI-WIRE MODE  
Please note in bi-wire mode that the link bars must be removed. Unscrew the knurled nuts on both  
the positive and negative HF and LF terminals and remove the link bar and then replace the colour-  
coded nuts, as they will be required to clamp the bi-wire cables in place. Retain the link bars in a safe  
place for possible future use.  
POSITIONING AND FINE-TUNING  
To get best results from your new Tannoy Eyris DC loudspeakers it is worthwhile spending a little time  
finding the optimum set-up configuration.  
Begin by angling the speakers towards your chosen listening position, usually this is on the centre line  
of the room, so that when seated you can just see the inner side panel of each speaker. The front of  
the loudspeaker should not be obstructed in any way. The loudspeakers should be located between  
1.5 to 4.5 metres (5ft to 15ft) apart - with the listening position set slightly further away than the  
speakers are apart. Avoid positioning the loudspeakers in corners of the room, as this will have a  
negative effect on performance. Ideally, maintain a distance of at least 0.5 metres (20 inches) from  
the rear wall, and 1 metre (39 inches) from the side.  
* Be sure that the amplifier is switched OFF and then prepare the two sets of cabling for each 'side'  
of the system separately. Measure and cut four lengths of cable, two per speaker.  
Label two of the cable lengths Left LF and Left HF (low frequency and high frequency) then repeat  
this process for the right pair.  
* If your amplifier is not equipped with separate output terminals for bass and treble information then,  
at the amplifier end of the cables, twist the Left LF+ (positive) and the Left HF+ (positive) together.  
Connect these to the amplifier Left channel positive terminal marked + (plus) or coloured red.  
With the speaker in its listening position, rock the loudspeaker gently from side to side so that the  
spikes find their way through the weave of the carpet and on to the solid surface below. Once fine  
adjustments have been made to the spikes, to level the loudspeaker and ensure stability, tighten the  
lock nuts firmly but without using undue force. (See fig. 7)  
Twist the Left LF- (negative) and the HF- (negative) cables together and connect them to the amplifier  
Left channel negative terminal marked - (minus) or coloured black.  
At the loudspeaker end connect the cables labelled Left LF+ and Left LF- to the left hand loudspeaker  
LF terminals, ensuring that you note the polarity markings on the cable sheathing.  
BASS TUNING  
Then proceed to connect the Left HF+ and Left HF- to the HF terminals on the same loudspeaker.  
These Eyris DC speakers have been designed for use in rooms with average to good acoustics without  
port damper bungs fitted. However, in smaller rooms where loudspeaker positioning is forced closer  
to rear or sidewalls, the foam port damper bung supplied in the accessory kit can be inserted into the  
reflex port. This will reduce the bass energy but 'speed-up' the sound presentation.  
* Repeat this process to connect the right hand loudspeaker to the amplifier right channel output, once  
again ensuring that polarity is correct throughout.  
* Switch the amplifier on with the volume control set at its lowest setting. Select a favourite source and  
slowly turn up the volume to a low level. Check that bass and treble information is being reproduced  
from both speakers - if not, switch off the amplifier and recheck the connections. (See fig. 5)  
There is no absolute right or wrong here, therefore much will depend on your own musical preferences.

GRILLES  
CENTRE CHANNEL SPEAKER  
It is essential that the SuperTweeterdiaphragms 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 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 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.  
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:  
PROTECTIVE TWEETER GRILLES ARE SUPPLIED FITTED TO THE SUPERTWEETERHOUSING.  
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.  
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.  
CARE OF CABINET  
The cabinets should only be cleaned with a dry cloth or with a light application of quality non-silicone  
furniture polish.  
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.  
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 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 OmniMountstyle 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.  
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)  
WARNING:  
FOR WALL MOUNTING INSTRUCTIONS SEE PAGE 5 AND FIG. 9, WHILST ALSO REFERRING TO  
THE MANUAL PROVIDED WITH YOUR CHOSEN OMNIMOUNTSTYLE BRACKET.  
THE SYSTEM  
SUBWOOFER  
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.  
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.  
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  
Concentricmodels (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.  
Please refer to the manual supplied with the subwoofer for advice on installation and set-up.  
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.
