Installation place
This unit shall be installed in a well�ventilated and effectively
heat�released place.
Especially, installation of this unit where direct sunlight is
present, where the temperature rises excessively high such
as close to a heater, or where it is humid or dusty may cause
a malfunction even if heat is efficiently released. Therefore, do
not install this unit in such places.
Ventilation holes
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.
Cautions in connecting speakers
When making speaker system connections, exercise extra
care not to short�circuit between ! and @ of the speaker
terminals and speaker input terminals of this product. If a
large signal is applied to the amplifier with its circuit left short�
circuited, a large current may be passed through the output
circuit and cause a malfunction.
The sound is not generated shortly after
the power supply is turned on.
This amplifier is equipped with a time muting circuit in order
to separate the output circuit. Therefore, no sound is gener�
ated shortly after the power supply is turned on. If the volume
control is moved to a high sound level before the time mut�
ing circuit is canceled, a large sound is suddenly generated.
Please be advised that the volume control shall be set to a
low level at first and adjusted after sound comes out of the
speakers.
Protection circuit
This product is equipped with the protection circuit that is
activated upon detection of overcurrent, abnormally high
temperature, and DC drift to protect the amplifier and speak�
ers. When the protection circuit is activated, the output to the
speaker terminal is shut off and the standby indicator blinks to
show that this product is in the muting state. If the protection
circuit is frequently activated after a lapse of a certain time
and turning on the power again, please consult your dealer.
Precautions in connecting with other
components
When connecting this product to input devices such as a CD
player, a Super Audio CD player, a tuner, and a recorder, be
sure to turn off the power of this product and all other con�
nected devices. Failure to observe this may generate a strong
noise resulting in speaker damage or cause a malfunction.
The pin�plug to be inserted in each input terminal of this prod�
uct shall be pushed in firmly. If the grounding terminal is inad�
equately connected, noises including hum may be generated,
resulting in an adverse S/N ratio.
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 repairs or adjustments are needed, please ask your
dealer where you bought the product.
Cleaning
For cleaning, use a piece of soft cloth to wipe the product
such as cleaning cloth available on the market. If the prod�
uct has become remarkably 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.

player and the PHONO terminal of this unit with 2 (R and L)
pin�plug cables. For some types of players, the ground wire
from the phono motor or the tone arm should be connected
to the ground terminal of this unit.
The phono equalizer of this unit uses the MM or MC car�
tridge. If an MC cartridge with low output voltage is used,
set the phono MC switch on the front panel to on.
The output from a record player equipped with a phono
equalizer or from an independent phono equalizer shall be
connected to the LINE input terminal of this unit.
How to connect recorder
1. Connection to monitor terminal
(playing)
Connect between the line output terminals (LINE OUT) of a
recorder and the monitor terminals of this unit with pin�plug
cables in consideration of R and L. Now, setting the input
selector to rec�1 or rec�2 provides playback.
How to connect PRE OUT/MAIN IN terminal
Either the pre�amplifier or main�amplifier can be separately
used.
When the pre�amplifier or main�amplifier is separately used,
set the separate switch on the front panel to on.
When only the pre�amplifier is used, connect the PRE OUT
terminal of this unit to the input terminal of another power�
amplifier, and when only the main�amplifier is used, connect
the MAIN IN terminal of this unit to the output terminal of
another power�amplifier.
When this amplifier is used without separating between
pre-amplifier and main-amplifier, set the separate switch
on the front panel to off, or no sound is generated.
2. Connection to REC OUT terminal
(recording)
When the sound source from the various input devices is
reproduced, which are connected to the PHONO or LINE
terminals of this unit, setting the recording selector to the
source to be recorded allows users to provide the REC OUT
terminal with the signal. Connection between the REC OUT
terminal of this unit and the line input terminals (LINE IN) of
the recorder with pin�plug cables is required for recording
on the recorder. After the connection, you can enjoy listen�
ing to the sound from the speaker system and record the
sound at the same time. These output signals for recording
are not affected by the control functions such as the volume
control and tone control functions.
When both of the input selector and the recording selector
are set to the line-2 position, the LINE-2 unbalance/bal-
ance selector toggles the recorder output terminals on the
rear between the unbalance input terminal (LINE-2) and
balance input terminal (BALANCED LINE-1)
