MASTER ANTENNA AND
OTHER
75-OHM
SYSTEMS
Some buildings have master antenna systems
that carry
FM.
Connect
to
the
75-ohm
ANTENNA terminal on the
rear
of
the unit.
Note:
For
clarification,
if
necessary, see
your
dealer,
who
can
advise
you
concerning the best antenna installations.
LOUDSPEAKER
The
R-1070
Tuner-Amprifier
is designed
to
drive
2
pairs of
speakers, used
either
separately or 2 together.
Because
of
its
high
output power,
two
pairs
of
even
the
lowest-eff
iciency 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 tuner-amplifier,
it
is
recommended that
you
use
standard guage
rip
cord. For
runs
over
1
5m
(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
the
insulation
of
one conductor, 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 (112"\
of
wire should be
bared
for
hookup, since longer
bared lengths may produce a short
ci rcu
i
t.
(2)
Twist all strands of
exposed
wire
tightly.
Loose strands may
cause
shorts.
CONNECTING SPEAKERS
Look
at your
speakers.
You
will
note
that
one
terminal
is
unmarked,
The other
will
be
designated
'COM',
'COMMON',
'GND', 'GROUND',
or
Black.
Connect
the
'COIV'
terminal of
each speaker
to
the appropriate black
SPEAKERS
terminal
on
the
rear
of the tuner-amplifier by
loosing
the terminal knob
and
inserting
the
bare
wire in
the hole,
then
fasten
the
knob.
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 tuner-amplifier.
To connect
a single
pair of
speakers,
connect the wires
from
the
left
speaker
(asviewed
from
the listening
position)to
the
"LEFT"
A
SPEAKERS
terminals. Similarly, connect the right
speaker
to
the "RlGHT" A
SPEAKERS terminals
of
the
tuner-amplifier.
The
2nd
pairs of
speakers can be connected
similarly
to
the
B
SPEAKE
RS
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-pictched
sounds
will
sound weaker
than they
should, and
the
stereo effect
at
higher frequencies
will
become
indistinct.
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
thin, or
weak,
the
speakers are
out
of
phase. Should this occur, turn
off
the
tuner-amplifier
and
carefully
check the connections
at
either one
of
the speaker.
TURNTABLES/TAPE
RECORDE RS/DECKS
AUTOMATIC

The
R-1070 has
2
provisions
for
connection
of
two
turn-

the
cartridge manual
or your
dealer,
if
in
doubt
about
the
firoper input
for
the particular cartridge
in
your
turntable. The
turntable's power cord can be
connected
to
the
extra AC outlet on the
rear
of the
R-1070,
if it
is provided.
