FEATURES
1. LOW DISTORTION POWER AMPLIFIER
SECTION
The power amplifier section is composed of a current mirror
load differential amplifier, a class-A amplifier, and an
inverted Darlington type pure complementary circuit.
The first stage is a transistorized differential amplifier to
which a current mirror circuit is loaded. The current mirror
circuit increases the gain at the first stage and assures low
distortion and stability.
The power amplifier stage consists of an inverted Darlington
type pure complementary circuit to improve the power
supply efficiency and to obtain high output power.
If DC voltage exceeding specified limit is developed at the
output terminal, the protective circuit turns off the relay to
prevent the speakers from being damaged. This circuit also
functions as a delay start circuit.
2. SEPARATION OF LEFT AND RIGHT
CHANNELS POWER SUPPLY
This power supply system is of DPS (dual power supply)
type with a 2-winding transformer. The power transformer
uses a large sized El core to provide excellent regulation.
The combination of this transformer and a large filter
capacitor forms a dual power supply system to supply power
to L and R channels respectively.
This power supply system eliminates dynamic crosstalk as
well as it assures reliable operation of the amplifier. The
power supply unit for the preamplifier is equipped with a
transistorized power voltage regulator to improve the circuit
operation stability and the quality of sound.
3. TONE CONTROL CIRCUIT
The tone control circuit has FET at the first stage; it also
contains dual power supply unit, 2-stage direct-coupled flat
amplifier and bass/treble control circuit. This control circuit
is so called BAX type NF control circuit that assures high
stability and low distortion. The flat amplifier is of the ICL
(input capacitorless) type to adjust bass and treble tones up
to ±7.5 dB at about 1.5 dB steps, thus enabling fine
adjustment of tonal quality.
4. ICL EQUALIZER WITH FET CIRCUIT
This circuit is a simplified ICL circuit consisting of FET input
amplifier, class-A amplifier and pure complementary SEPP
amplifier.
The use of newly developed super low noise FET and
cleverly designed circuit reduces the impedance of the entire
circuit to improve S/N ratio to 86 dB (2.5 mV input, IHF A).
The adoption of precision resistors and film capacitors
provides RIAA characteristic with error of ±0.3 dB.
5. SPECIAL TAPE-THROUGH CIRCUITRY
This unit has facilities for simultaneous recording by two
tape decks and for dubbing from deck A to B. In addition,
Kenwood's tape-through circuitry allows you to dub while
listening to a different program source. This may not be a
feature you will use every day, but it is quite practical and
will be appreciated when the occasion arises.
6. LARGE POWER METERS VISUALLY
SHOW OUTPUT POWER
With these full-size Power meters you always know what
your amplifier is doing. You can visually check output and
balance channels.
A refinement for audiophiles, these meters are large and
illuminated for easy reading. Notice that sensitivity is
adjustable for operation at both high and low levels to get
maximum range in both cases. High: 0.1W to 80W; low,
0.01 W to 3W.
7. TWO SPEAKER SYSTEMS
You can attach two speaker systems and select either or
both.
8. LOUDNESS CONTROL
This control (-h8 dB at 100 Hz) boosts especially the low
frequency range at a low listening level and offers you
splendid stereo reproduction.
9. BALANCE CONTROL
This control performs the volume adjustment of right/left
speakers and headphones.
10. EXCELLENT DESIGN
Kenwood's excellence of design and superior craftsmanship
is evident not only in the electronics of the unit but also in all
the controls.
11. OTHERS
• 41 -click master volume to suit audiophiles' tastes.
• Subsonic filter of 18 Hz, 6 dB/oct.

CONNECTING INSTRUCTIONS
SPEAKER CONNECTING AND SPEAKERS
SWITCH
In connecting only one pair of speakers, con¬
nect the right speaker to "RIGHT" and left speaker
to "LEFT" of the SPEAKERS A terminals. Should
( + ) or ( —) of either right or left channel be
reversely connected, sounds at the center section
will be adversely affected by lack of separation.
To connect an additional pair~of speakers, connect
right speaker to "RIGHT" and left speaker to
"LEFT" of the SPEAKERS B terminals.
When connecting the speaker leads to the
speaker terminals, make sure that the bare wires
strands at the tips of the speaker leads do not
touch each other or adjacent terminal.
It is recommended that the wires of in¬
dividual cord lead tips are soldered, or they are
stranded together to eliminate any possibility of
short-circuits forming in the speaker connecting
network.
Note: -
Each speaker should be 4 ohms or more in impedance when
only one pair of speakers are used. However, it should be 8
ohms or more when two pairs of speakers are used at the
same time (A + B).
TURNTABLE CONNECTION
The two shielded audio cables from your
stereo turntable are normally terminated with
phono plugs. Connect the left channel of the turn¬
table to "LEFT" of the PHONO input jack and the
right channel to "RIGHT" of the PHONO input
jack.
If the turntable has a grounding wire, con¬
nect it to this unit's GND terminal to avoid hum.
TUNER CONNECTION
Use the TUNER terminals for connection to
an FM stereo or AM-FM stereo tuner.
Connect the left channel of the tuner to
"LEFT" of the TUNER input jack and the right
channel of the tuner to "RIGHT" of the TUNER in¬
put jack.
AUX (AUXILIARY INPUTS)
High level AUX input jacks are for mis¬
cellaneous sources, such as extra tape decks, ad¬
ditional tuners and/or receivers, TV sound outputs,
and other external components.

TAPE DECK CONNECTION
Recording
A tape deck can be connected for recording
as follows: the left channel input of the tape deck
to "LEFT" of the TAPE A REC jack, the right
channel input of the tape deck to "RIGHT" of the
TAPE A REC jack.
Playback
A tape deck can be connected for playback
as follows: the left channel output of the tape
deck to "LEFT" of the TAPE A PLAY jack, right
channel output of the tape deck to "RIGHT" of the
TAPE A PLAY jack.
If an additional tape deck is used and two
tape decks are operated simultaneously, the same
connections must be provided for the TAPE B
jacks.
DIN CONNECTOR (REC/PLAY CONNECTOR)
If your tape deck is equipped with a DIN
connector, connect it to the TAPE B REC/PLAY
connector with a DIN connecting cord. A DIN
connector enables recording and playback with
this single cord.
Notes:-
1) The REC/PLAY connector corresponds to the TAPE B
REC and TAPE B PLAY jacks - the signal must be con¬
trolled with TAPE switch on the front panel.
2) When a DIN cord is used for connecting to the tape
deck, the TAPE B PLAY and TAPE B REC jacks should
not be used.

CONTROLS AND FUNCTIONS
(g) POWER meters
These meters indicate the strength of the output
volume level. They can be read directly in watts
from 0.01 to 80 watts on the scale for speaker im¬
pedance of 8 ohms (controlled by the Meter
Range switch). When speaker impedance is 4
ohms, output power is twice the figure on the
scale. If speaker impedance is 16 ohms, output
power is then half the scale amount. However,
musical signals actually assume complex wave
forms with much variations, and the indicated
power corresponds approximately to the mean
value of these wave forms.
(D METER RANGE switch
This switch controls the sensitivity of both the left
and right channel output level meters. Use the
switch suitable for your listening requirements.
Note: -
To protect the meters from overswing, make it a practice to
move up the switch to the "80W" first, and advance
successively to "3W” when no deflection can be observed.
©LOUDNESS switch
This switch boosts bass response to compensate
for the human ear's lack of response to those fre¬
quencies at low volume levels.
This switch should be set to "OFF" when listening
at normal and high levels.
@ TONE switch
In position "DEFEAT", the bass and treble control
do not function. By switching between "DEFEAT"
and "ON", this enables you making frequency
response measurements of phono cartridges,
speakers and the acoustic conditions of the room.
(Q) TONE controls
These controls are for adjusting the bass and tre¬
ble response. They are a click step type control by
approximately 1.5 dB. Turning the controls
clockwise increase bass and treble response and
counterclockwise decrease bass and treble
response. Bass and treble controls do not func¬
tion when the TONE switch is set to "DEFEAT".
©SUBSONIC FILTER switch
Frequencies below 18 Hz are attenuated by 6
dB/octave. Although such subsonic frequencies
are inaudible to the human ear, they can cause in¬
termodulation distortions and even damage to the
speakers. It is recommendable to set the lever
"ON" at all times, even if no record rumble etc. are
heard. "OFF" position is no attenuation of sub¬
sonic frequencies.

MAINTENANCE
CLEANING PRECAUTIONS
Do not use volatile liquid such alcohol,
thinner, gasoline, benzine, etc., when cleaning the
unit surface. Use silicon cloth or soft dry cloth.
POWER PLUG
• Switch off the unit and disconnect the power
plug from your AC outlet immediately if the
abnormality should take place.
• When you connect or disconnect the power
plug from your AC outlet, never do it with wet
hands to avoid unexpected accident from elec¬
tric shock. Besides, do it by holding the power
plug itself, not the power cord.
• It is desirable to disconnect the power plug
from your AC outlet when you leave your
house for a long time.
POWER CORD
• The power cord must not be pulled strongly,
nor bent forcibly, nor scratched, nor extended
by connecting an extra cord. This will damage
the cord and be a cause of electric shock and a
fire.
• Do not put a heavy thing on the power cord.
PREVENTION OF INTRUSION OF METALLIC
SUBSTANCE IN UNITS
The case top is provided with ventilation
holes. Never close these holes with ornamental
cloth, etc. Be careful not to put a coin, hairpin,
needle, etc., into the unit through the holes.
Otherwise, it may be a case of malfunction and
electric shock. Such trouble is often caused by in¬
fants.
PREVENTION OF MODIFICATION
Each unit is shipped after passing careful
adjustments to the optimum operating con¬
ditions. The unit interior must not be modidified.
Some parts of the interior are applied with high
voltage. Never dismantle the case and touch the
internal parts. Only the qualified servicemen are
in charge of check-in the interiors.
PROTECTION OF SPEAKERS SYSTEM
Lower the sound volume when switching the
amplifier on or changing over the program source
to another. You should make it a rule to move the
volume control knob to a low sound level before
you turn the POWER switch on. Sudden feeding
of a large input power may damage the speaker
systems. If you keep such a habit, the speaker
systems can be protected against the attack of
violent noise occurring when a stylus is put on a
disc or broadcasting station is selected.
ACOUSTIC FEEDBACK
Occasionally a disturbing howling sound
caused by acoustic feedback, may be heard. This
is generally caused by the relative positions of the
turntable and speaker enclosures. The sound
pressure radiated from the speaker box surrounds
and vibrates the turntable.
This vibration is picked up by the cartridge,
sent to the unit as an electrical signal, and return¬
ed to the speaker. This again causes the speakers
to radiate vibration which induces sympathetic
vibrations in the turntable and cartridge. Sym¬
pathetic vibrations are reinforced with each
repeating cycle and result in an undesirable sound
called oscillation or “howling". To prevent it, keep
your turntable away from your speakers. Also
mounting your turntable on shock-absorbing pads
may help.
