BI-AMPING
Inthis mode the H.F. and L.F.
sections of the crossover are again
separated but are now connected to their
own dedicated amplifier. This method of
connection gives small but noticeable
gains both in clarity and control.
Four speaker cables and four ampli-
fier channels are now required (for instance
two stereo amplifiers can be used).
Note - It is very important that all the
amplifiers used have the same gain and
polarity characteristics, we strongly rec-
ommend that you consult with your dealer
as to the suitability of your equipment if
you are considering this method of con-
nection.
GRILLES
The KT2s are supplied fitted with
grills which are made from an acousti-
cally transparent cloth. Some listeners
may wish to remove these grilles if they
feel that they alter the perceived sound
quality. However we recommend that the
grilles are left in place at all other times
as they offer some degree of protection
to the drive units.
FEET
The KT2s come ready fitted with
rubber feet which are suitable for most
situations. Optionally these can be
replaced with adjustable gold plated
conical spikes available from Kelly
Transducers. These can be fitted by
simply unscrewing the bolt which se-
cures the rubber foot and then screwing
in the new spike assembly. Other spikes
which use an M6 fixing thread may also
be suitable.
NORMAL (SINGLE) WIRING
In normal (single) wiring use, the two
pairs of terminals on the rear face of the
KT2 are linked together with the supplied
gold linking bars. You can attach your
speaker cable pairs to either the top or bot-
tom sets of posts. This connection can be
made by either 4mm banana plugs (which
will fit into the end hole of the post), spade
terminals or bare wires.
Note - It is important in all wiring
schemes that the + output terminal of
the amplifier is wired to the + input ter-
minal of the speaker and the - output
terminal of the amplifier is wired to the
- input terminal of the speaker in the
same way on both speakers. If this con-
nection is not maintained (incorrect
channel polarity) the sound may appear
weak and 'phasey' with reduced bass
output .
BI-WIRING
When bi-wiring, the linking bars are
removed and the H.F. (high frequency) and
L.F. (low frequency) parts of the crosso-
ver become separated. Two sets of cables
are now connected from each amplifier
channel to each speaker. This can give
small but noticeable gains in clarity. Tak-
ing each speaker in turn, one set of cables
connects to the upper (H.F.) pair of bind-
ing posts on the KT2 and a second set con-
nects to the lower (L.F.) pair of binding
posts. If at the amplifier end there are two
sets of terminals (two + and two -) per
channel you can simply attach each cable
to its respective binding post. If there is
only one set of terminals per channel then
you will need to connect both plus cables
to the same terminal post and similarly
both minus cables to the same terminal
post.
