Check
that the

range
marked
on
the
back
matches
the
supply
before
you
connect
the
unit.
The77
is
supplied
with
an
AC
power
lead
with
a
moutded
13A
3
pin
plug
with
1
3A f
use. Do
not
cut
off this
plug
or
use it
with
its
fuse
cover
removed.
lf however
for
any reason
the
plug
has
to
be removed
then
it
must
be
disposed
of and
under
no
circumstances
plugged
into
a 13A
socket
ouilet.
A
suitable
plug
can
be
fitted,
as
explained
below:-
IMPORTANT
-
Fitting
a mains
ptug.
The
wires
in
the
mains
lead
are coloured:
Brown
=
Live
Blue
=
Neutrat
The
Brownwire
must
be
connected
to the
terminal
marked
L
orcoloured
Red.
The
Blue
wire
must
be
connected
to
the
terminal
marked
N
or
coloured
Black.
lf
the
lead
also has
a GreenNeilowwire
than
this
must
be
connected
to the
terminal
marked
E or
coloured
Green
or
Green/yellow.
when
a fused
13A
plug
is
used
a
13A
fuse
(ASTA
approved
to BS1362)
will be
adequate
for
a typical
Quad system.
For
other
types
of
plug,
then
fit
a 13A fuse
either
in
the
plug,
or adaptor,
or
at
the
distribution
board.
tt in
oount
consult
a
qualif
ied
electrician.
This
is
not
critical
and it
may
be
operated
free
standing
or stacked.
Note
that
the
amplifier
can
deliver
substantial
amounts
of
power.
ihe
diecast
housing
will
provide
more
than
adequate
cooling
for
normal
domestic
purposes
but if
the
amplifier
is
played
at very
high
volume
levels
for
extended
periods
then
adequate
ventilation
must
be
provided
- the
case
will
become
quite
warm
to
the
touch.
Do
not
place
audio
or
video
cassettes
on top
of
the amplifier
because
the
magnetic
fields
produced
by
its
mains
transformer
may
affectthe
quality
of their
recordings.
The
Quad
77
integrated
amplifier
is fitted
with
standard
binding
posts.
lt is
unconditionally
stable
and can
be used
with
any
type
of loudspeaier
cable.
For
optimum
performance
it is
necessary
to
ensure
that
the
resistance
of the
cable
is
small
relative
to the loudspeaker
impedance.
eUAD
loudspeaker
cable
gives
the
best
results.
Each
loudspeaker
should
be
connected
to the
appropriate
output
terminals
so
that the
two
pairs
of
wires
are connected
in
the
same way,
to
ensure
that
the
speakers
are
correctly
phased.
The
output
terminals
are
colour
coded
to
facilitate
this.
should
there
be
any
doubt the
phasing
can
be
checked
experimentally.

phasing,

for
infomation
on
how
to
check
for
correct
phasing.
