Bi-wire Mode
LINKS REMOVED
Please note in bi-wire mode that the link cables should not be used. Best results will be
obtained with a specially designed bi-wire speaker cable.
If your amplifi er is not equipped with two sets of output terminals, twist the Left LF+ (positive)
and the Left HF+ (positive) together at the amplifi er end of the cables. Connect these to
the amplifi er Left channel positive terminal marked + (plus) or coloured red. Twist the Left
LF- (negative) and the HF- (negative) cables together and connect them to the amplifi er 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. Then proceed to connect the Left HF+ and Left HF- to the HF terminals on the
same loudspeaker.
Repeat this process to connect the right hand loudspeaker to the amplifi er right channel output,
once again ensuring that polarity is correct throughout.

17 Quick Start Guide
Bi-amping extends the principle of bi-wiring one stage further. In this connection option,
separate power amplifi ers are used for bass and treble signals in each loudspeaker. Four mono
(or two stereo) amplifi ers of the same type are required for a stereo pair of loudspeakers.
If two stereo amplifi ers are used, it is recommended that one amplifi er supply bass information
to left and right loudspeakers and the other, the treble information. It is important not to use
the link cables on the terminal panel, otherwise amplifi er damage may result.
Treble Adjustment
Each loudspeaker is fi tted with two controls located on the front baffl e beneath the detachable
grille. These high current switch blocks are labelled ROLL OFF and ENERGY. They can be
used to compensate for the varied acoustic characteristics of listening rooms. The controls
should be adjusted with the amplifi er tone controls in the 'fl at' or uncompensated position.
Each loudspeaker should be adjusted individually. Rotating the amplifi er balance control, to
select fi rst one loudspeaker and then the other, most easily achieves this.
The Energy control has fi ve positions. It allows the output of the high frequency compression
drive unit to be increased or decreased from the linear or 'fl at' position over a frequency band
from approximately 1 kHz to 27 kHz. The Roll Off control has fi ve positions (+2, level, -2, -4 and
-6 dB per octave) and provides adjustment at extreme high frequencies from 5 kHz to 30 kHz.
The Energy control has a shelving eff ect whereas the roll off control increases or decreases
the slope of the extreme high frequency response. The fl attest, most linear response from the
loudspeaker will be obtained with both controls set at the LEVEL position, and this position
should be used for initial listening tests. If the overall quality of the high frequency sound
seems too prominent the –1.5 or –3 positions for the Energy control should be tried. If the
sound appears subdued in the treble region +1.5 or +3 settings may be preferred. Once the
energy control setting has been established the Roll Off control can be adjusted to reduce or
slightly increase the extreme high frequency content if necessary.
Remember the changes that can be made by moving either control from one position to another
are subtle. They may not easily be heard if the programme material has very little content in
the frequency band under consideration. Choose a well-balanced piece of music with a full
spectrum of sound. The correct setting will be found when the loudspeakers are no longer
evident and only the musical performance is heard.

Cabinet Care

The cabinet is fi nished to exacting standards utilising carefully selected solid hardwood
mouldings and matching real wood veneers. The wood should only be cleaned with a dry cloth
or with a light application of quality non-silicone furniture polish such as the specialist Tannoy
wax supplied in the accessory pack. Take care not to get polish on the grille cloth or lacquered
front baffl e.
In common with all solid wood furniture, exposure to extremes of heat, cold and varying
humidity will cause the wood to ease slightly. Therefore it is recommended that the
loudspeaker is protected from
environmental extremes to guard against any such occurrence. Any wood will change colour
when subjected to the UV content of ambient light and dry out over time, hence the need to
'feed' the wood with the wax provided periodically.
