INSTALLATION
P]ace
the
unit
on
a
stable
rigid
sur&ce
with
at
least
Im
(3ft.)
of
free
space
above
it.
If
you
are
using
a
turntable,
ensure
that
the
tonearm
is
least
400
mm
away
from
the
amplifier
to
minimise
any
hum
conduction
and
ideally
on
a
separate
shelf.
If
you
have
to
use
the
turntable
and
the
amplifier
on
the
same
surface,
place
the
turntable
to
the
right
of
the
amplifier
to
maximise
the
distance
between
the
tonearm
and
the
amplifier.
Avoid
placing
the
amplifier
in
front
of
the
loudspeakers
to
avoid
vibrations
fioro
the
speaker
drive
units
causing
microphonics
in
the
amplifier
and
degrading
the
sound.
If
this
is
your
first
valve
amplifier
please
familiarise
yourself
with
some
important
issues
surroundlt^
the
safe
use
of
the
QUAD
II
Classic
Int^raied
amplifier
Valves
Get
Hot
Valve
power
amplifiers
generate
a
lot
of
heat
even
with
no
input
so
it
is
ntal
to
ensure
adequate
ventilation
for
your
amplifier.
Although
the
protective
cages
over
the
valves
get
hot
they
are
very
unlikely
to
cause
a
burn.
For
absolute
safety
the
unit
should
be
placed
out
of
the
reach
of
children
and
pets
and
away
from
heat-sensitive
objects.
Valve
Amplifiers
Work
at
High
Voltages
Valves
require
a
high
voltage
to
function.
Do
not
open
the
case.
Also
ensure
that
nothing
is
poked,
dropped
or
poured
into
the
amplifier's
case.
The
environment
should
be
dry
and
free
from
liner.
Do
not
place
magnetically
or
thermally
sensitive
objects
(i.e.
credit
cards
or
optical
discs)
close
to
the
unit.
Valves
are
Microphonic
Because
valves
are
constructed
from
fine
wires
and
tiny
metal
parts
they
can
pick
up
external
vibratiotts.
If
you
place
the
power
amplifier
too
close
to
the
speakers,
direct
sound
at
high
volumes
may
vibrate
the
valves.
1
metre
(3ix)
to
the
side
of
each
speaker
should
be
considered
a
sensible
minimum.
Interconnects
and
Cables
The
signal
inputs
to
the
amplifier
ate
via
RCA
phono
connectors.
As
valve
equipment
works
at
high
impedances,
the
phono
interconnects
from
source
units,
and
especially
from
the
pickup
cartridge
should
be
well
screened
and
of
a
low-noise,
low-capacitance
construction.
To
minimbe
capacitance
and
other
ef^ts,
signal
interconnects
should
be
kept
as
short
as
possible.
Choose
good
quality
loudspeaker
cable
designed
for
the
purpose
rather
than
general
purpose
‘zip’
or
‘bell’
wire.
The
cable
should
be
of
adequate
gauge
to
maximise
bass
performance.
We
do
not
recommend
high
inductance
or
capacitance
cables
as
these
can
have
a
significant
and
deleterious
ef&ct
on
valve
amplifier
output
stages.
Mains
Earthing
(Grounding)
Thb
amplifier
requires
connection
to
an
earthed
(grounded)
mains
supply.
In
your
sound
system,
the
amplifier
should
be
the
only
device
connected
to
mains
ground
to
negate
hum
induced
by
ground
loops.
For
thb
reason
we
surest
that
you
avoid
using
interconnects
with
separate
ground
wires.
If
any
of
your
other
equipment
b
grounded
a
“hum
loop”
may
arise.
If
thb
happens
please
consult
your
dealer
for
advice.

Before
connecting
youi
amplifier
all
components
in
the
system
must
be
unplugged
at
the
mains
and
the
volume
control
of
the
amplifier
set
at
zero.
When
making
stereo
conneaions,
RCA
plugs
and
sockets
coded
white
or
black
usually
indicate
the
LEFT
channel
and
those
coded
red
the
RIGHT
channel.
In
a
sKteo
pair
of
sockets
the
upper
socket
is
usually
the
Left
Channel
and
the
lower
socket
the
Right.
If
you
are
in
any
doubt,
consult
a
qualified
dealer.
Connecting
a
Turntable
Bejbre
connecting
the
unit
please
read
the
instructions
that
came
with
your
pickup
cartridge,
turntable
and
tonearm.
Ensure
all
active
units
in
your
system
are
switched
off.
Signal
coanecdoas:
Most
tonearms
come
with
captive
phono
cables.
If
your
turntable
has
phono
sockets
you
will
need
a
steteo
RCA
cable.
Connect
the
turntable
phono
outputs
to
the
Phono
Inputs.
Push
the
plugs
firmly
into
place
to
make
secure
contaa.
Ensure
the
Left
and
Right
channels
are
correedy
connected.
Ground
Connectionst
Most
turncable/tonearm
combinations
use
a
ground
wire;
some
use
separate
ground
wires
for
turntable
and
tonearm.
If
your
turntable
has
phono
socket
outputs
you
may
need
as
a
ground
wire
a
single
length
of
stranded
wire
the
same
length
as
the
signal
cables.
Connect
the
ground
wire/s
to
the
Input
Ground
terminal.
Unscrew
the
ground
terminal
p>an
way
and
insert
the
spade
connector
under
the
terminal.
If
the
cable
does
not
have
a
s|>ade
connector,
bare
a
short
length
of
wire
and
insert
this
under
the
left
side
of
the
terminal.
T^hten
firmly.
Note
1:
Some
turntables
do
not
use
a
ground
wire
hut
have
a
cartridge
negative
return
lead
connected
internally
to
the
tumtable/tonearm
chassis.
Note
2:
Some
cartridges
have
a
negative
sigrudpin
linked
to
the
metal
cartridge
body.
If
the
cartridge
boefy
contacts
the
tone
arm
metalwork
via
the
connecting
hardware
this
may
cause
a
hum
loop.
Consult
your
dealer
before
you
remove
this
link.
Note
3:
If
you
use
a
high
capacitance
RCA
cable
to
connect
a
moving
magnet
cartridge
to
the
turntable
input
you
may
cause
an
audible
peak
in
the
high
frequency
response.
If
you
are
in
any
doubt
consult
your
dealer.

FURTHER
INFORMATION
Running
In
New
Equipment
Running
in
k
very
important.
Valve
components
vrark
at
high
voltages
and
temperatures
and
when
new
th^
should
spend
an
eittended
period
at
those
temperatures
to
bed
in.
We
recommend
you
run
the
amplifier
in
for
at
least
four
and
preferably
twelve
hoius
before
you
first
use
it.
If
you
run
in
your
equipment
for
this
extended
period,
make
doubly
sure
dtat
all
the
safety
conditions
covered
in
this
manual
are
fully
met.
Supervise
the
equipment
for
the
first
hour
or
so
and
if
you
have
to
leave
the
unit
unattended
thereafter,
look
in
occasionally
to
make
sure
all
is
well.
Warming
Up
Before
Use
Allow
at
least
fifteen
minutes
for
the
amplifier
to
'warm
up'
before
use.
If
you
play
loud
music
while
the
system
is
cold
the
output
valves
will
not
be
fully
operational
and
the
amplifier
will
be
starved
of
voltage
and
current.
The
resulting
distortion
is
unpleasant
and
potentially
damaging
to
the
amplifier's
valves
and
your
loudspeakers.
Intensive
use
of
the
equipment
before
it
has
warmed
up
will
shonen
vaKc
life.
Valve
Lifetimes
Valves
contain
a
heating
element.
This
heats
up
the
valve's
cathode,
which
is
coated
to
give
off
a
steady
stream
of
elections.
After
a
few
years
this
coating
will
begin
to
wear
out
and
performance
will
gradually
deteriorate,
the
Kr66
output
valves
are
likely
to
deteriorate
first
but
the
driver
valves
will
also
eventually
wear
out.
As
the
valves
start
to
wear
out
the
sound
will
become
less
well
defined
and
a
lack
of
dynamics
and
power
will
become
evident.
Replacing
the
valves
with
a
new
set
will
fully
restore
the
audio
performance
of
the
amplifier.
When
replacing
valves
it
is
essential
to
use
the
highest
quality
available.
Poor
quality
valves
will
adversely
affect
the
sound
quality
and
may
in
extreme
cases
damage
the
amplifier.
When
replacing
the
output
valves,
use
matched
sets
for
best
results.
Do
not
leave
the
amplifier
permanently
switched
on
or
you
will
seriously
shorten
the
lifispan
of
your
valves!
Output
Transformer
After
installing
oi
changii^
the
wiring
to
your
speakers,
keep
the
volume
control
at
zero,
let
the
amplifier
warm
up
and
turn
up
the
main
volume
gradually.
If
you
don't
hear
sound,
switch
off
immediately
and
investigate.
The
output
transformer
is
designed
to
match
the
fai^
voltage,
low
current
conditions
in
which
the
output
valves
operate
to
the
low
voltage
high
current
requiremencs
of
a
loudspeaker.
Although
robust,
an
output
transformer
can
be
damaged
and,
in
extreme
cases
wrecked,
by
careless
use.
If
you
play
a
valve
amplifier
into
a
short
cirruit,
the
output
transformer
will
soak
up
a
lot
of
energy
before
failing,
but
if
the
short
persists
the
transformer
could
be
damped.
Operating
a
valve
amplifier
at
high
output
levels
with
TU!
loudspeaker
connected
can
also
damage
an
output
transformer.
Overall
Volume
Levels
Output
levels
from
different
source
components
in
a
high
fidelity
system
can
vary
widely.
A
CD
player
can
produce
levels
significandy
higher
(>18
dB
)
than
an
FM
tuner.
It
foUows
that
the
position
of
the
volume
control
is
not
a
guide
as
to
'how
loud'
the
equipment
will
go.
Though
the
overload
characteristics
of
the
amplifier
are
such
that
you
can
play
your
music
at
surprisingly
high
levels,
if
the
sound
is
distorted,
you
are
overloading
your
equipment
whatever
the
position
of
the
volume
control.

CARE
AND
CLEANING
The
sur&ce
of
the
equipment
may
be
cleaned
with
a
damp
doth
provided
that
the
power
haa
been
removed
first.
Solvent
based
cleaning
materials
should
never
be
used
as
they
may
damage
the
paint
finish.
