Earth
Terminal

Connect
the
earth
lead
wire
of
the
record
player
(from

or
pickup
arm)
to
ground
the
amplifier.
€
Tape
Connector
(CONNECTOR)
This
connector
is
of
DIN
standard.
With
the
recording
output
terminal
(REC OUT)
and
the
tape
monitor
terminal
in
it,
con-
nection
for
recording
and
playback
is
feasible
with
a
single
lead-
wire with
DIN
plug—
providing
the
tape
recorder
has
the
same
connector.
For
playback
through
this
connector,
the
Monitor
Switch
(12)
must
be
at
the
“deck-1"
position,
and
the
Dubbing
Switch
(13)
at
the
SOURCE
position.
Recording
output
signal
is
always
available
from
this
connector,
except
when
the
dubbing
switch
is
set
at
the
‘’2
to
1”
position.
@
PHONO-1
Terminal
For
playback
through
magnetic
cartridge
(MM,
MI,
MC
type).
Input
sensitivity,
2.2mV.
Input
impedance
is
selectable:
50Kaq,
65Ka,.
and
90Ka.
Except
for
very
low
output
MC
type
cartridge
(output
voltage,
0.01mMV-0.1mV).
almost
all
cartridges
can
be
used.
For
such
MC
type
cartridges
of
very
low
output
level,
it
is
necessary
to
boost
voltage
up
to
the
specified
level
by
use
of
step-up
transformers
or
a
head-amoplitier.
&
Input
Impedance
Selector
for
PHONO-1
This
selector
permits
selection
of
desired
impedance:
50Kaq,
65Kao,
and
90Ka.
With
MM
type
cartridge,
frequency
response
varies
according
to
load
impedance.
For
the
cartridges
which
tend
to
intensify
the
high
frequency
range,
set
the
load
impedance
at
the
50Ka
position.
On
the
contrary,
for
those
which
tend
to
attentuate,
setting
at
9OKQ
is
recommended.
Because
the
car-
tridge
of
65Ka
is
presently
dominant
in
the
market,
this
ampli-
fier’s
selector
is
set
at
65Ka.
€&
PHONO-2
Terminal
Same
as
PHONO-1
Terminal,
except
that
the
input
impedance
is
fixed
at
65Ka.
&
TUNER
terminal
For
reproduction
of
tuner
(AM/FM/LW/SW).
The
input
level
can
be
adjusted
by
the
Level
Control
for
TUNER
terminal
(28).

These
are
auxiliary
input
terminals
for
playback
of
flat
frequency
response
such
as
AM/FM
stereo-tuner,
line
output
of
a
tape

or
the
audio

DECK-1
REC.
OUT
Terminal
(Recording
Output
Terminal)
A
signal
for
recording
is
taken
out
from
this
terminal
(always
available
when
an
input
signal
is
given
to
any
of
the
input
termi-
nals).
In
case
the
Dubbing
Switch
(13)
is
set
at
the
“2
to
1”
position,
the
recording
signals
come
from
the
DECK-2
recording
output
terminal.
@
‘“DECK-1”
Monitor
Terminal
Playback
of
the
line
output
of
a
tape
recorder
is
possible
from
this
terminal.
It
is
put
into
operation
when
the
Monitor
Switch
(12)
is
set
at
the
‘“deck-1”
position.
In
case
a
3-head
tape
re-
corder
is
used,
simultaneous
playback
monitoring
is
possible.
&
“DECK-2”
REC.
OUT
Terminal
(Recording
Output
Terminal)
Offers
the
same
function
as
the
DECK-1
REC.
OUT
terminal
(31).
lf
the
Dubbing
Switch
is
set
at
the
1
to
2”
position,
the
signal
from
the
DECK-1
terminal
is
available.
If
the
Dubbing
Switch
is
at
the
SOURCE
position,
the
recording
signals
are
fed
to
both
DECK-1
and
DECK-2
terminals
for
simultaneous
recording
on
2
tape
recorders.
In
case
a
matrix
4-CH
decoder
is
used,
this
terminal
has
to
be
connected
with
the
input
terminal
of
the
decoder
with
a
pin
jack
cord.
