are
independent
of the mains

is
always
available,
while
the

is coupled
wìth
the

and
supply
of
the mains
power
depends
on
the mains
switch.
The
maximum
capacity
for

SPEAKER
TERMINALS
(A.B.C.
SPEAKERS)
The
speaker
systems
are to be connected
to these
terminals
Press
the cap
of
the
terminal
and insert
the speakers
bare
cord to the
terminal hole.
Then release
it. Now firm
connection
is finished.
These terminals
are coupled
with
the speaker
selector
switch
(23),
and the
selector switch
must be
set at the very
position
corresponding
to
the

MUTING LEVEL
CONTROL
This is
effective
on FM
programmes
to select
the

is
at the

TAPE CONNECTOR
This
5-pin
connector is
of DIN standard. With recording
output(REC.
OUT) and tape monitor(TAPE N/ONITOR)
terminals in it, connection for recording
and
playback
is
feasible
with a single
lead-wire
of DIN
plug
¡f the tape-
recorder has the same connector.
For
playback
through
this connector the moniÌor switch(11) must
be at the
"deck-1
" position.
Recording output signals
are
always
available from
this
connector.

ln case
normal reception
is
possible
with the built-in
bar
antenna, it is
not
necessary
to use
this terminal.
But
when
reception
of a weak signal
is desired,
connect a

a simple
wire antenna
is used for this terminal it
is
not always
necessary to have
a
ground
connection which sometimes deteriorates
sensi-
tivity.
A
full

to decrease
undesired
noises.

as lead-in wire.
A

connected
-
a

This
is an auxiliary

playback
of flat

(0.01-0.1mV)"
For
such IVC
type cartr¡dges
of

it is needed
to boost the voltage
up
to the
specified level
by use
of
step-

This is
effective
on
AM
programmes.
When

to negligible
level
Normally
this

position.
NOTE
Thls receiver
can be used
as a front
or rear
amplifier
of
quadraphonic
reproductìon.
ln
case
you
have 4-channel
recorder,
front or
rear 2-channel

be reproduced
by
this
amplif ier
section. Connect
the recording
output terminal
of
this receiver
with the
input terminal
of 4-channel
