Rack installation
Audio racks, LA-V 4500 or LA-4500 are recommended.
NOTE:
*
Eyen
when
using
an
audio
rack
which
is
not
designated,
be
sure
to
leave
spaces
around
the
components
to
allow
the
heat
to
dissipate,
and
make
sure
that
the
amplifier
and
tuner
are
separated
by
a
shelf.
*
Eyen
when
an
audio
rack
is
not
used,
it
is
recommended
that
the
amplifier
be
placed
above
the
tuner
in
order
to
allow
the
heat
to
escape
efficiently.

IMPORTANT FOR U.K.:
The
wires
in
this
mains
lead
are
coloured
in
accordance
with
the
following
code:
Blue: NEUTRAL
Brown: LIVE
As
the
colours
of
the
wires
in
the
mains
lead
of
this
apparatus
may
not
correspond
with
the
coloured
markings
identifying
the
terminals
in
your
plug
proceed
as
follows.
The
wire
which
is
coloured
BLUE
must
be
connected
to
the
terminal
which
is
marked
with
the
letter
N
or coloured BLACK.
The
wire
which
is
coloured
BROWN
must
be
connected
to
the
terminal
which
is
marked
with
the
letter
L
or coloured RED. :
FEATURES
1.
Dual
Gate
MOS
FET
for
High
Quality
FM
Tuner
Dua!
Gate
MOS
FET
provided
in
the
front-end
and
3
gang
variable
capacitors
offers
excellent
FM
sensitivity,
intermodulation
characteristics,
high
S/N
ratio
and
spurious
rejection.
2.
High
Selectivity
and
Low
Distortion
IF
Amplifier
Using
IC
and
3
Ceramic
Filters
A
3-stage
differential
amplification
is
used.
By
the
extensive
use
of
IC,
together
with
3
ceramic
filter
elements
that
have
good
phase
characteristics,
in
the
FM-IF
amplifier
there
is
a
great
improvement
in
the
limiter
and
selectivity
characteristics.
3.
Quadrature
Detection
Quadrature
detection,
using
IC
extensively,
has
a
wide
band
coverage
and
low
distortion.
4,
Phase-Locked
Loop
for
FM/MPX
Circuit
PLL-IC,
which
was
developed
by
HITACHI,
is
used
for
FM/MPX
circuits,
and
high
separation
and
low
distor-
tion
are
achieved;
also
high
reliability
is
achieved
as
far
as
the
effects
of
temperature
and
aging
are
concerned.
5.
FM
Mode/Muting
Circuit
A
Mode/Muting
switch
which
combines
the
mode
changeover
and
muting
functions
is
used.
6.
MPX
Noise
Filter
Circuit
:
Since
an
MPX
noise
filter
circuit
is
employed,
high
frequency
noise
can
bé
cut
during
the
reception
of
FM
stereo
broadcasts.
