FM ANTENNA
In strong signal area, an FM dipole antenna supplied with the re-
ceiver should
be more
than adequate
for reception of most FM
stations.
Antenna
connections
are
made
to the terminal
strip
marked
FM, located on the rear panel.
The dipole should be un-
folded
to its full T size and oriented
for optimum
performance
because
the dipole antennas
are most
sensitive
when
positioned
perpendicular to the station.
If the supplied dipole is not sufficient
for satisfactory reception of FM stereo stations, or for reception in
fringe (weak
signal) areas
where
interference
to FM reception
is
high, the use of Log-periodic
or Yagi antenna
system
is recom-
mended.
These antennas are directional and high gain in nature,
thus tending
to reduce most interference due to reflected signals
(multipath distortion) and ignition noise.

POWER ON/OFF
This switch turns the power on (depressed) or off (released).

SPEAKER SWITCHES A/B
These permit you to select one of 4 listening conditions.
A:
When
depressed,
connects
the
sound
output
to the
speakers attached to the Speakers A output terminals on rear
panel.
B:
When
depressed,
connects
the
sound
output
to the
speakers attached to the Speakers B output terminals located
next to the Speakers A output terminals.
Depressing both switches in position connects the sound out-
put simultaneously to the speakers attached to the Speakers
A and Speakers B output terminals, and if both switches are
released, all speakers
are silenced and the sound output is
connected
only to the headphones plugged into the Phones
jack located to the right side of the cabinet.
Since the signal
is always fed to this jack regardless of the switch selection,
it is recommended
that
the
headphones
be disconnected
when not in use to avoid possible overload.

DIGITAL FREQUENCY
READOUT AND INDICATORS
In this recessed display panel, four indicators are built in.
Frequency Readout:
This indicator gives a direct readout of
frequency which the receiver is tuned in, by means of LED.
Signal Strength Indicator:
Used for tuning on AM, and also
shows relative signal strength on both AM and FM.
As the
incoming signal level increases, the indicator advances from
left to right.
Center Tuning
Indicator:
Used
for precise tuning to the
center of an FM station to assure the optimum FM reproduc-
tion.
Adjust the Tuning Control 5) for simultaneous lighting
of both LEDs vis-à-vis.
SOURCE SELECTOR
Selects the program
source
to be reproduced
through the re-
ceiver, provided that the Tape Monitor switches 1/2 are set
to the Source (released) position.
Phono:
Selects the output of stereo turntable connected to
the Phono input jacks on rear panel.
FM:
Selects automatic FM stereo reception.
Hi-Blend:
Activates a circuit which reduces high frequency
noise in weak
FM stereo reception.
This filter does not af-
fect the frequency
response
but reduces
slightly the high
frequency stereo separation.
AM:
Selects AM reception.
Aux:
Selects the program source connected to the Aux input
jacks.
TUNING CONTROL
Used to tune across the AM
or FM band.
See Digital Fre-
quency Readout 3).
TAPE MONITOR SWITCHES 1/2
Select outputs from tape decks connected to Tape Play 1 or
Tape Play 2 input jacks.
Program source selected originally
by the Source Selector 4) cannot be heard through speakers
unless these switches are placed in released position (Source).
When
these two
switches are depressed
in positions simul-
taneously, tape copying from deck
1 to deck 2 is possible.
See Tape Deck Operation.
TONE CONTROLS TREBLE/BASS
Allow you to adjust the tonal balance of the sound output.
Bass:
Increases or decreases the level of the low frequencies
in the program
material.
Clockwise
rotation
increases
and
counterclockwise rotation decreases.
Treble:
Operates
in the same
manner
as the Bass tone
control,
except
it provides
adjustment
of high frequency
levels.
HIGH FILTER
È
Used to remove high frequency noise sometimes encountered
in program
materials.
Such
noise
might be experienced
when
playing a worn record or a tape having excessive hiss.
Since all high frequency filters have some effect on the high
frequency response of the program material, they should not
be
used
unless
disturbing
high
frequency
noise
is present.
Depress to use.
FM MUTE
Introduces
a special
muting
circuit
which
eliminates
noise
between
stations on FM.
When
listening to weak stations,
this switch should be switched off (released) to prevent the
receiver from switching to a mute condition due to reduced
signal strength.
MODE SWITCH/STEREO-MONO
Determines
the manner
in which
program
material will be
reproduced through the left and rigt t channels.
Stereo (released):
Provides stereophonic reproduction of any
stereo
program
source.
This position
also provides
auto-
matic FM stereo reception.
Mono (depressed):
A program source connected to the left
and
right
channel
input jacks
is mixed
and
reproduced
through both channels.
LOUDNESS SWITCH
When
released to On position, compensates
for dificiencies
in human
hearing ability at low listening levels based on the
Fletcher-Munson
curves, this means audio levels of high and
low frequencies are boosted.
VOLUME/BALANCE
CONTROLS
These 'controls are located concentrically: the small knob is
the Volume, and the large knob nearer to the panel is the
Balance control.
Volume:
Permits adjustment of the volume for both left and
right channels simultaneously.
Balance:
Provides left to right channel balance of the pro-
gram
material.
Normally
this control
should
be set to its
center (12 o'clock) position.
OPERATION
With receiver installed and connected
as outlined, proceed
as fol-
lows:
AM RECEPTION
Rotate the Source Selector 4) to AM position.
Rotate the Tuning
Control
5) to select desired station.
A properly tuned AM station
is indicated
by maximum
Signal
Strength
indicator
3) reading.
Adjust loopstick antenna for maximum
signal.
During AM recep-
tion, FM Mute switch 9), Mode switch 10), and FM Center Tuning
indicator 3) are inoperative.
FM RECEPTION
Rotate the Program Selector 4) to FM position.
Rotate the Tuning
control
5) to select desired
FM
station.
The receiver will auto-
matically switch from monaural
to stereo FM operation when tuned
to an FM stereo broadcast provided that the Mode switch 10) is set
to Stereo (released) position.
Stereo broadcasts are indicated by
the illuminated Stereo indicator in the display area 3). When listen-
ing to weak stations, placing the Program selector 4) in the Hi-Blend
position will reduce background
noise by cancelling out of phase
noise component.
USING A TAPE DECK
To listen to a prerecorded tape, simply select the appropriate Tape
monitor
switch to depress and play the tape on the desired tape
deck.
To record a stereo program, select the desired program source
on the Program selector 4).
This will produce a recording signal
at both Tape 1 and Tape 2 Rec output jacks.
If you wish to moni-
tor the program
information
that is being recorded, depress either
the Tape 1 or Tape 2 Monitor switch 6). In addition to the record-
ing using one tape deck, simultaneous recording for two tape decks
is possible
using
the
same
procedure
as stated
above.
However,
when
monitoring the program
information
that is being recorded,
do not try to use Tape 1 Monitor switch 6), as this channels the pro-
gram
signal which
is detoured
through tape deck 1, into the tape
deck 2.
TAPE COPYING
In order to duplicate a tape from tape deck
1 onto tape deck 2,
perform the following.
Make sure the inputs and outputs of both
tape decks
are connected
to the Tape
1 and Tape 2 Rec and Play
jacks respectively.
Depress both the Tape
1 and Tape 2 Monitor
switches
6) simultaneously.
Play
the
tape
on
tape
deck
1 and
record it on tape deck 2.
HEADPHONES
The receiver is provided with a standardized 6.35 mm
phone jack
for a stereo headphone plug. You can connect every low impedance
(4 to 16 Ohm) or mid-impedance (200 to 2,000 Ohm) headphone.
To disconnect
all the speakers connected
to the receiver, simply
release both the Speakers A and Speakers B switches 2) at the same
time.
TROUBLE SHOOTING
GUIDE
The
following guide is intended
as an aid in correcting problems
encountered when setting up the stereo system.
Although the sug-
gested remedy might seem quite elementary, it may be sufficient to
make corrections without returning the receiver to your dealer.
