4. To protect your speakers and amplifier from damage it is important to ensure that the
amplifier is switched OFF prior to connecting or disconnecting any cabling.
Correct polarity of the cable connections between the amplifier and speakers is essential.
(See figure 2)
For optimum performance when connecting the system in standard single wire mode to a
speaker terminal panel equipped with full bi-wiring facility, always make cable connections, with
the links fitted, to the HF terminals.(See figure 2)
The positive (plus) terminal on the amplifier left channel (marked + or coloured red) must be
connected to the positive 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.
The negative (minus) terminal on the amplifier left channel (marked - or coloured black) must
be connected to the negative 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.
FINE TUNING
To get best results from your new Tannoy loudspeakers it is worthwhile spending a little time finding
the optimum set-up configuration. Here are a few tips to help you with this process:
STAND MOUNTING AND BOOKSHELF SPEAKERS
Small speakers should not be placed directly on the floor but can be used on bookshelves or tables.
However, the sound reproduction quality achieved will never be as good when not ideally positioned.
Your dealer can show you a selection of purpose built stands, designed to realise the full performance
potential of your loudspeakers.

BASS TUNING
Begin by angling the speakers towards your chosen listening position, usually this is on the centre line
can be inserted into the reflex port. This will reduce the bass energy but 'speed-up' the sound presentation.
Many Tannoy loudspeakers are also provided with a foam port damper bung inside the port tube
located on the front or rear panel of the cabinet. The speakers have been designed for use in rooms
with average to good acoustics without these dampers fitted, so please take them out before use.
In smaller rooms, where loudspeaker positioning is forced closer to rear or side walls, the port damper
There is no absolute right or wrong here, therefore much will depend on your own musical preferences.
POSITIONING
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.
All models are fully shielded to eliminate colour fringing effects when placed close to televisions.
Avoid positioning the loudspeakers in corners of the room, as this will have a negative effect on
performance; maintain a distance of at least 0.5 metres (20 inches) from the rear wall, and 1 metre
(39 inches) from the side. (See figure 3)
BI-WIRING
Where the facility to bi-wire your loudspeakers is provided we would strongly recommend that you
install your system using this wiring option. With this method you will require separate cable feeds from
your amplifier to the HF and LF units of each loudspeaker. Generally this will result in a significant
improvement in resolution, transparency, stereo focus and instrument separation.
QUICK SET UP
PLEASE REFER TO THE SPECIFICATION AND INSTALLATION DIAGRAM SHEET SUPPLIED WITH THIS
MANUAL
1. Remove the loudspeakers from all packaging.
Fold the carton flaps right back and invert the carton and contents.
Lift the carton clear of the contents.
Remove all the inner packaging from the product.(See figure 1)
It is strongly recommended that you store all the packaging to allow protected transportation
in future.
2. Stand mounting or bookshelf speakers should be located securely in an appropriate position. If wall
mounting any speakers, we strongly recommend that you use a bracket which will support the base
of the speaker. Use of a bracket that screws directly onto the back panel of the speaker can cause
too much strain to be exerted on the fixing point and the panel itself. This may cause panel
detachment when in use and could present the risk of injury.
3. Floor-standing models perform best with carpet piercing spikes fitted. These are supplied, along
with lock nuts, and should be fitted into the threaded holes in the base of the cabinet. 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.
Loudspeaker stands should be rigidly built and preferably mass loaded with dry sand. The optimum
listening height will be dictated by the seating in your room, usually between 300mm (12") and 600mm
(24") high. Stand mounted speakers will produce their best stereo image and soundstage if you can
just see the top face of the cabinet. Check the 'lift' needed to put the speakers in this position before
purchasing your stands.
Refer to the paragraph headed Positioning for stand mounted speaker placement advice.
(See figure 3)
FLOOR STANDING LOUDSPEAKERS
For optimum performance from floor-standing loudspeakers, the design team at Tannoy recommends
that the supplied carpet piercing spikes be fitted. A rigid footing for the speaker, with a secure interface
between the cabinet and the floor, brings about an improvement in clarity, bass 'speed' and definition.
First level the spikes by eye then hand tighten the lock nuts. 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 level the loudspeaker and ensure stability, tighten the lock
nuts firmly but without using undue force.
Refer to the paragraph headed Positioning for floor standing speaker placement advice.
