INTEGRATED AMPLIFIER L-590AX
1
Precautions
Installation place
This unit shall be installed in a well-ventilated and effectively
heat-released place because this unit is an A-class amplifier
and generates considerable heat.
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
The ventilation holes on the top and bottom boards of this
product must not be blocked because this unit is an A-class
amplifier and generates considerable heat. 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. Failure to observe this
may cause a malfunction.
Note:
For heat dispersal, do not install this equipment in a confined
space such as a book case or similar unit.
Precautions in connecting with other
components
When connecting this unit to input devices such as a CD
player, an SACD player, a tuner, and a recorder, be sure to
turn off the power of this unit and all other connected 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 unit
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.
Cautions in connecting speakers
When making speaker system connections, exercise extra
care not to short-circuit between!and@of the speaker ter-
minals and speaker input terminals of this unit. 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 generated
shortly after the power supply is turned on.
If the volume control is moved to a high sound level before
the time muting 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 a protection circuit that is ac-
tivated upon detection of overcurrent, abnormally high tem-
perature, and DC drift to protect the amplifier and speakers.
When the protection circuit is activated, the output to the
speaker terminal is shut off and the standby indicator blinks to
show that this unit is in the muting state. If the protection cir-
cuit is frequently activated even when disconnecting the pow-
er plug from the wall outlet and turning on the power again
after a lapse of a certain time, please consult your dealer.
Batteries
Caution:
Batteries used for remote controller shall not be exposed to
excessive heat such as sunshine, fire or the like.
Repair and adjustment
When repairs or adjustments are needed, please ask the
dealer 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.
