KR-5200 FEATURES
Frequency-Linear Variable Capacitor
The dial scale has linear graduations (arranged at the same intervals)
to make tuning easier.
Front End with 2 FET Circuits
The front end contains FET circuits together with one dual gate
element. These circuits assure high sensitivity, worthy of the name
KENWOOD.
1-IC and 3-Element Mechanical Filter
The 3-element mechanical filter is employed in the IF stage. It
improves the characteristics of capture ratio and selectivity.
Independent AM and FM Circuits for the IF Stage
The FM circuit for the IF stage is separated from the AM circuit.
Such a scheme is effective in the reduction of mutual interference.
Newly Developed DSD Circuit and MPX Circuit
The double switching system and the carrier leak block filter have
been adopted. They are a great aid in improving the de-emphasis
frequency characteristic and especially, improvement of stereo
separation.
Large Meter with Built in Lighting Mechanisms
The KR-5200 has a large-scale meter for tuning convenience.
Protected Semi-Complementary Direct-Coupled Power Amplifier
The power amplifier is a protected semi-complementary direct-
coupled type which assures stabilized high performance.
Equalizer Circuit with PNP Can-Type Transistor
The preceding circuit employs a PNP can type transistor for the
improvement of S/N ratio and circuit reliability.

CONNECTING YOUR KR-5200
SPEAKER CONNECTIONS
CONNECTING ONE PAIR OF SPEAKERS
To connect only one pair of speakers, connect the speaker leads
to the “A” SPEAKERS terminals as follows.
The (—) side lead from the left speaker should be connected to the
L (-) terminal of “A” SPEAKERS, and the (+) side lead to the L (+)
terminal. Similarly, connect the right speaker leads to the R terminals
of VA” SPEAKERS. Be sure to connect (+} to (+) and (—) to (—}.
CONNECTING ADDITIONAL SPEAKER SYSTEMS
When you connect additional speaker systems to the KR-5200,
connections to the B SPEAKERS and/or C SPEAKERS terminals should
be made as described above. Observe polarity at all times when making
speaker connections.
NOTES:
1. When only one pair of speaker systems is used with connections
made either to the ‘A’ SPEAKERS terminals or ‘’B’’ SPEAKERS
terminals, sound cannot be heard when the SPEAKERS switch
on the front panel isset to the A + B position. Likewise when only
one pair of speaker systems is used with connections made either
to the A or C SPEAKERS terminals, sound cannot be heard when
the SPEAKERS switch is set to the A + C position.
Any speaker with a impedance of 4 to 16 ohms can be used.
3. When connecting the speaker leads to the SPEAKERS terminals,
make sure that the bare wire strands at the ends of the speaker
leads do not touch each other or adjacent terminals.

PHASING OF THE SPEAKERS
Speaker phasing can be determined in the following manner:
1. Set the SELECTOR switch to FM
. Set the MODE switch to MIX
. Tune in the desired station with the TUNING knob.
If the sound is coming directly from the front, the speakers are in
phase. If the sound comes from both sides and there is a noticeable
loss in low frequencies. the speakers are out of phase.
In this case reverse the leads on one speaker

Since FM broadcast signals travel along a straight, direct-line path,
they
become
rather
weak
behind
hills
and
buildings
even
in
the
vicinity
of
a
broadcasting
station.
FM
signals
also
become
weak
in
areas distant from a station even though there may not be any obstruc-
tion to the direct line path of the signal. Therefore, a good FM antenna
should be installed in the most effective manner for best possible FM
reception.
In areas near the FM station where signals are strong, stretch the
T-type indoor antenna that is supplied to its maximum, and connect it
to the FM 300 &2 terminals on the rear panel. This antenna should
be carefully hung in the direction that provides best reception with
minimal undesirable reflection.
An
outdoor
FM
antenna
will
become
necessary
if
interference
is
encountered
as
a
result
of
weak
FM
signals
with
an
indoor
antenna.
if
a

employed,
it

AM ANTENNA
The ferrite stick antenna incorporated in your KR-5200 assures
satisfactory reception from all local AM stations. Since the ferrite stick
antenna has directional properties, you should adjust the antenna to
the position at which the strongest signal is received.
In fringe areas where satisfactory reception cannot be obtained
with the ferrite stick antenna, an AM outdoor antenna should be con-
nected to the AM terminal.

CONNECTIONS FOR TAPE RECORDER
RECORDING
A tape recorder can be connected as follows for recording.
Left channel input of the tape recorder to A TAPE ‘‘L” REC jack.
Right channel input of the tape recorder to A TAPE ‘’R” REC jack.
PLAYBACK
A tape recorder can be connected as follows for playback.
Left channel output of the tape recorder to A TAPE “’L” PLAY jack.
Right channel output of the tape recorder to A TAPE “R” PLAY jack.
DIN CONNECTOR (REC / PLAY CONNECTOR)
If your tape recorder is equipped with a DIN connector, connect
it to the REC/PLAY connector with a DIN connecting cord. A DIN
connector enables recording and playback with this single cord.
NOTE:
When a DIN cord is used for connecting to the tape recorder, the
PLAY and REC jacks should not be used.
For highest fidelity recording and playback sound, however, it is recom-
mended that the tape recorder be connected to the PLAY and REC
jacks instead of the DIN connector.
RECORD PLAYER CONNECTIONS
Connect the left channel of the record player to the ““L’” PHONO
input jack, and the right channel to the ‘’R’’ PHONO input jack.
If the record player has a grounding terminal, connect it to this
receiver's GND terminal to avoid hum.
AUX (AUXILIARY INPUTS)
When a tuner, tape recorder or other unit is connected here, it
must have an output of at least 150 mV.
AC OUTLETS
The AC outlets on the rear panel of the receiver may be used to
supply power to other components such as a record player, tape
recorder, etc.
1. SWITCHED outlet
This outlet is controlled by the POWER switch on the front panel.
(The capacity is GO watts maximum.)
2. UNSWITCHED outlet
This outlet is available at all times. (The capacity is 300 watts
maximum.)
PRE OUT
The preamplifier output of the KR-5200 is obtainable here.

CONTROLS
AND
THEIR
FUNCTIONS
BALANCE control
This BALANCE adjusts unequal volume from any program
source
in
right
and
left
channels,
The
left
channel
is
accen-
tuated when this adjuster is turned trom center “5” toward
the left side, and conversely.
VOLUME control
The VOLUME control performs simultaneous adjustment
of volumes in both channels (right and left}, Set it to your
own most satisfactory listening level.
TAPE MONITOR switches
(A and B)
The TAPE MONITOR switch-
es are used when operating a
tape recorder for monitoring
a recording or for tape repro-
duction. With the button
Pushed in, sound recorded on
the tape is heard. When the
button is released, the source
signals is heard.
If a tape recorder connected
to the A TAPE jacks on
the rear panel is used, the
TAPE MONITOR A must be
switched on. When the TAPE
MONITOR B is pressed, the
tape recorder connected to
the B TAPE jacks on the
front panel becomes availa-
ble.
The TAPE MONITOR switch-
es should be kept switched
off (by button release) unless
monitoring or tape reproduc-
tion is performed
FM MUTING switch
This switch silences intersta-
tion noise on the FM band,
but it may also eliminate the
signal of a weak and distant
station along with the inter-
station noise. Therefore, set
this switch ta OFF {by press-
ing button release} in the re-
ception of a weak and distant
station.
LOUDNESS control
The LOUDNESS control
boosts bass and treble tones
at low listening levels. Our
ears have less sensitivity to
low and high frequencies at
low listening levels and the
LOUDNESS control com-
pensates for this deficien-
cy. This control should be
switched off when listening
at normal and high levels.
LOW and HIGH FILTER
switches
LOW FILTER — Pressing
this button switch reduces
low frequency noise such as
turntable rumble, hum, etc,
on pragram materials. Gen-
erally, this filter should be
used anly when necessary
HIGH FILTER — Pressing
this button switch reduces
high frequency noise suchas
tape hiss, record scratch, etc.
Generally, this switch should
be used only when necessary. ;
SELECTOR switch TUNING knob
The TUNING knob selects
the desired AM or FM station
signal. Adjust it for maximum
deflection of the TUNING
meter as you listen to the
sound output from the speak-
ers
Switch positions and func-
tions are as follows:
AM — For AM reception
FM For the reception of
both FM monaural and stereo
signals. Automatic switching
operates between FM mon-
aural and stereo sources.
When an FM stereo broadcast
is tuned in, the STEREO in-
