Operation Manual

INSTALLATION
While the R-1
500
Receiver has been designed for
maximum
ease
of installation and operation, we strongly suggest
you
read
this section through before
proceeding
to
connect
and
operate
the unit.
Because the
B-1500
incorporates
manV
technical
and
operating refinements, it may be
a
bit
different from equÌpment
you
have
used
in the
past.
PLACEMENT AND MOUNTING
The R-1500
may
be
placed
in
virtually
any
convenìent loca-
tion,
keeping
in
mìnd the necessity of connecting cables to
your
speakers and an antenna
for FM. Because of
its
advanced solid-state
construction, the unit
produces
little
heat. But certain minimum ventilation
requirements
are
still necessary to
provide
optimum operation:
When the R-1500 is
placed
on an open shelf in a bookcase
or cabinet
(mounted
in its integral
metal case
or
with the
accessory
furniture case)
about
10 cm of
freespaceshould
be
allowed
above it.
POWER REOUIREMENTS AND
MAINS
CONVE
NIENCE
OUTLETS
(E.TYPE,
U-TYPE)
The R-1500 Receiver
operates on the mains
power
only
100-125, and 210-250
volts,
50-60H2,
consuming 350 watts
maximum at
full
power
output. Three convenience
outlets
are
provided
on the
rear
panel
to supply the
mains
power
for additional components
suÇh
as
automat¡c or manual
turntables, tape
recorders, etc.
The mains
cord of a turntable should be
connected to one
of the unswilched
outiets, to
permit
it
to
rotate
f
u
lly
before
turning on. The mains
cords
of other
components
can
be
connected
either
to
the sw¡tched outlet, and
they
will be shut off when
the receiver is turned
off. Not
more
than
100
watts
totai should be
drawn from the
unswitched
outlets,
nor the switched outlet.
(lf
in doubt
about the
wattage
drawn
by
additional
components, check the
ratings
on their rear
panels,
or in their
manuals, Automatic turn-
tables,
for
instance,
generally
draw
from
20-50
watts.)
ANTENNAS
with
the
R-1500.
For FlV, a
folded
dipole,
available
from
your
dealer,
is
generally
adequale.
This section
will tell
you
how to connect them.
AM ANTENNA
ln
all but remote
rural locations, the
special
fold out
ferrite
core antenna
mounted
on the
rear
of
the receìver
provìdes
excellent AIV reception.
For the
best results, make
certain
that this antenna
is
folded out away
from the chassis to its
maximum
extens¡on. lf an
external
antenna
is required,
connect a
length of wire
(any
type will do)
to the AM
ANTENNA
Ìerminal on
the rear
panel.
FM ANTENNA
Folded
Dipole
Connect
the antenna
lugs to the
300-ohm ANTENNA
terminals on the rear
panel
Rotation of the FM antenna
for
best
reception
will be described under Tuning Control
in
the OPERATION section of this manual.
FM
OUTSIDE
ANTENNA
lf
you
live in a remote
fringe area, or
in
a
metropolitan area
with reception
problems,
it may be necessary to
use
an
outside antenna.
lf
you
require a separate FM antenna,
purchase
a
quality
FM
unit
from
your
dealer.
Connect
the
cable
from
lhe antenna
to the 300-ohm
ANTENNA
terminals on
the rear of the
R-1500.
MASTER
ANTENNA
AND OTHER
75-OHM
SYSTEMS
Some
buildings
have master antenna
systems that carry FlV.
Connect to the
75 ohm ANTENNA terminal on the
rear
of
the un¡t.
Note: For clarification, if necessary, see
your
dealer,
who can advise
you
concerning the best

A SPEAKER
B SPEAKÊR
LOUD SPEAKERS
The
R-1500
Receiver
is
designed
to drive 3
pairs
of
speakers, used either
separately or 2
together.
Because
of its high output
power,
two
pairs
of
even
the
lowest-efficiency
speaker systems may be used together
without
fear of
placing
too heavy a demand upon the
unit.
Although almost any type of wire
may
be used
to
connect
speakers
to the receiver,
it
is recommended
that
you
use
standard
guage
rip cord.
For
runs over
15m(50ft), heavier
gauge
rip cord should
be used
if
possible.
Whatever
thickness of
wire
you
choose,
pick
the type
where
you
can
distinguish one
lead from another, either
by
conductor
color,
a
ridge running
along lhe insulation of one con-
ductor,
or by a colored cord
under
the
insulation. This
will help
you
hook up
the speakers correctly.
PLEASE
NOTE
(1)
No more
than 1.5cm(1
l2"l
of wire should
be bared
for
hookup, since
longer bared lengths
may
produce
a
short
circu¡t.
(21
Twist
all
strands of expose'd
wire
tightly. Loose
strands may
cause
shorts.
CONNECTING
SPEAKERS
unmarked.
The other
will
be desingated
'CON/ì',
'COM-
MON',
'GND', 'GROUND',
or Black.
Connect the
'COM'
terminal of each
speaker to the appropriate black
SPEAK-
ERS
terminal
on the rear o1 the receiver
by
pushing
on the
terminal and
Inserting the bare
wire in the
hole
thus
exposed.
Make sure the
wire does not contact
the chassis
or
another terminal, to
prevent
shorts.
Then
connect
the
other speaker terminal to the
appropriate red
SPEAKERS
terminal
of the receiver. To connect
a single
pair
of
speakers, ccinnect
the
wires from
the left speaker
(as
viewed
from the
listening
position)
to the
"L"
A SPEAKERS
terminals. Similarly, connect
the right speaker
to the
"R"
A SPEAKERS terminals
of the receiver.
The 2nd and
3rd
pairs
of
pseakers
can be connected
si
milarly to B and C
SPEAKERS
terminals.
SPEAKER PHASING
To enjoy
good
stereo reproduction, it
is
necessary
that the
two
stereo
speakers
in any
location
work as a team,
'pushing'
and
'pulling'
the air
in unison. Otherwise, low-
pitched
sounds
will
sound
weaker than they should,
and
the stereo
effect
at higher frequencies
will become
indis-
tinct. To connect
your
speakers for
proper
stereo effect
(this
is
called
"phasing"),
proceed
as follows:
Play an FM
program
with the
Mode
Switch
in MONO
position.
lf the
low bass notes sound normal,
the speakers
are
properly phased.
lf they sound th¡n, or
weak, the
