BI-AMPING
The
performance
of
your
system
can
be
further
enhanced
over
that
achieved
with
bi-wiring,
by
extending
the
same
principal
one
stage
further
to
include
separate
amplification
for
the
low
and
high
frequency
speaker
drive
units
as
well
as
separate
loudspeaker
cables.
This
is
known
as
biamplifying,
or
bi-amping
for
short.
To
implement
bi-amping
therefore
requires
four
amplification
channels.
In
practice
this
is
done
by
using
two
stereo
amplifiers;
when
one
of
these
is
an
integrated
amplifier
it
is
best
to
use
this
drive
the
high
frequency
(HF)
units
whilst
the
outboard
power
amplifier
is
used
to
drive
the
low
frequency
(LF)
units.
We
recommend
you
use
one
of
the
following
combinations
for
the
optimum
price/performance
ratios:
Alpha
7
(HF)
plus
Alpha
8P
(LF)
Alpha
8
(HF)
plus
Alpha
8P
(LF)
Alpha
8
(HF)
plus
Alpha
9P
(LF)
It
is
also
possible
to
substitute
an
Arcam
Delta
290P
amplifier
for
the
Alpha
9P
as
their
sensitivities
are
identical.
HOW
TO
SET
UP
A
BI-AMPED
SYSTEM
1.
R
emove
the
shorting
links
from
each
of
the
red
and
black
terminal
pairs
on
the
rear
of
your
loudspeakers.
THIS
IS
ESSENTIAL
OR
DAMAGE
TO
YOUR
AMPLIFIERS
MAY
RESULT
WHICH
IS
NOT
COVERED
UNDER
WARRANTY.
2.
You
will
need
two
lengths
of
loudspeaker
cable
or
a
suitably
terminated
cable
capable
of
being
used
for
bi¬
wiring
in
one
length
and
one
stereo
amplifier
per
frequency
band.
3.
Connect
your
system
as
per
the
diagram
opposite
ensuring
correct
polarity
at
all
times.
The
positive
(+)
connections
on
the
loudspeaker
must
go
to
the
positive
(+)
connections
on
the
amplifier
and
the
negative
(-)
connections
on
the
right
loudspeaker
must
go
to
the
negative
(-)
connections
on
the
right
channel
of
the
amplifier
etc.
You
also
need
to
make
a
connection
from
the
preamp
out
sockete
of
your
integrated
amplifier,
or
preamplifier,
to
the
power
amp
in
sockets
of
the
power
amp.
ADDING
AN
ALPHA
8P
TO
AN
EXISTING
ALPHA
7
OR
8
INTEGRATED
AMPLIFIER
If
you
are
using
an
Alpha
7
or
8
amplifier,
an
Alpha
8P
can
be
added
to
bi-amplify
a
pair
of
biwireable
loudspeakers.
This
will
reap
substantial
improvements
in
sound
quality
if
the
following
advice
is
observed.
Always
switch
on
the
integrated
amplifier
and
allow
it
to
stabilise
(indicator
light
turns
green)
before
switching
on
the
Alpha
8P.
The
integrated
amplifier
and
Alpha
8P
power
amplifier
are
placed
on
separate
shelves.
