Precautions
Installation location
Install this unit where good ventilation and heat radiation are
assured. Do not install where the
temperature is abnormally high
such as in direct sunlight, or
where it is dusty or humid, as this
could result in damage to this unit
despite proper heat radiation. Do
not install this unit where it will
create problems for driving the
car.
Ventilation holes
The amplifier has many vacuum
tubes, generating much heat.
Never close the ventilation holes
located on the vacuum tube cover
and the bottom plate. If the amplifier is installed on a rack or the
like, secure ample space for cooling and leave the door open. Do
not pile up other things on the
amplifier and never put articles on
it. This can cause malfunctioning.
Note:
For heat dispersal, do not install
this equipment in a confined
space such as a book case or
similar unit.
Connection with other
components
When connecting this unit with a
CD/DVD player, tuner, or another
input unit, turn off the power
switches of this unit and all other
connected units. Otherwise, a
very strong noise may be generated and destroy the speakers. In
the worst case, this can cause
equipment malfunction.
The pin-plug to be inserted in
each input terminal of this unit
shall be pushed in firmly. If the
earth side is inadequately inserted, humming and such noise may
be generated, resulting in an
adverse S/N ratio.
Cautions for speaker
connections
When making speaker system
connections, be sure not to cause
short-circuiting between ! and @
of the speaker terminals and
speaker input terminals of this
unit. If signals are applied to the
amplifier with its circuit left shortcircuited, a large current may be
carried in the output circuit and
cause malfunctioning.
The sound is not generated
shortly after the power supply
is turned on.
This amplifier is equipped with a
time muting circuit intended for
the separation of the output circuit. For this reason, no sound is
generated shortly after the power
supply is turned on.
If the volume control is moved to a
high sound level before this time
muting circuit is canceled, a large
sound is suddenly generated as a
result. We therefore advise initially
setting the volume control at a low
level. After that, you may move
the volume control to your favorite
sound level after the initial sound
has come out of the speakers.
Batteries
Caution:
Batteries used for remote controller shall not be exposed to
excessive heat such as sunshine,
fire or the like.
Repair and adjustments
When repair and adjustments are
needed, please ask the store
where you bought the unit.
Cleaning
For cleaning, use a piece of soft
cloth to wipe the unit such as
cleaning cloth available on the
market.
If the unit has become very dirty,
remove the dirt with soft cloth
absorbing a small amount of neutral detergent, and then wipe the
unit with dry cloth. Do not use a
solvent like benzine or thinner
because such a substance can
often damage the exterior.

Names and Functions of Parts
1. Operation switch
(OPERATION)
This switch turns the power
supply ON/OFF. When the I/O
terminals are connected, turn
off this switch without fail.
When turning on the operation
switch again after turning it off,
wait for more than one minute.
2. Power indicator
When the operation switch is
on, this indicator is lit in yellow
to indicate that this unit is
presently energized.
3. Remote control infrared
receiver (R)
This is a sensor to receive signals from the accessory remote
control.
Do not place any objects in
front of the sensor.
4. Volume control (VOLUME)
This knob is used to adjust the
sound volume. In the position
fully turned to the left, no sound
is generated. As it is turned
clockwise, the sound volume
slowly increases.
5. Volume control indicator
This indicator is an index for the
sound level.
This indicator blinks in the middle of mute (silence) shortly
after the operation switch has
been turned ON, or when muting is performed with the
remote control.
6. Line straight switch
(line straight)
This switch is used to increase
the purity of the sound quality
by bypassing (skipping) the
tone control circuit.
7. Headphone jack (phones)
When you want to use a stereo
headphone, insert the headphone plug in this output jack.
When the plug is inserted, the
signal output to the speaker terminal is interrupted. When the
plug is pulled out, the signal
output is supplied to the speaker terminal again.

Names and Functions of Parts
8. Tone control
(TONE CONTROL, bass,
treble)
bass: This is a level control
to change the frequency characteristics in the
low-frequency range.
When it is set in the
center position, flat frequency characteristics
are obtained. Turning it
clockwise causes the
low-frequency range to
be emphasized, and
turning it counterclockwise results in attenuation.
This adjustment is
impossible while the line
straight switch is ON.
treble: This is a level control
to change the frequency characteristics in the
high-frequency range.
When it is set in the
center position, flat fre-
quency characteristics
are obtained. Turning it
clockwise causes the
high-frequency range
to be emphasized, and
turning it counterclockwise results in attenuation.
This adjustment is
impossible while the line
straight switch is ON.
9. Input selector
(INPUT SELECTOR)
This switch is used to select a
record player, CD/DVD player,
tuner, or other such component
connected to the input terminals.
There are four positions;
PHONO, CD, LINE-1, and
LINE-2. Each position corresponds to one of the input terminals on the rear panel. For
selection, adjust the knob to the
input position of your intended
playback.
This unit is an amplifier where
vacuum tubes are used. In the
state of the unit in operation, the
main body becomes hot. Be
careful not to touch it with your
bare skin. This unit should not be
used where small children are
present.
