*This product is an amplifier which has been designed using time domain theory in
order to maximize speaker operation and performance.
《What is time domain theory?》
Time domain recreates the changes that occur in sound waves over time from the
moment of output until their disappearance. Its purpose is to reproduce those
sound waves that are as close as possible to the original recorded sound.
Time domain audio systems allow sound orientation and the nuances that are
added by recorded performers to be faithfully reproduced.

Do not place the unit in direct sunlight, near
heating equipment or close to open flames. Fire
accident or malfunction may result. Do not place
the unit in locations exposed to cold air or direct
draft. Condensation, leakage current or thermal
damage may result. Do not use the unit in dusty or
dirty locations. Decreased heat ventilation can
cause thermal damage or fire.
8. Unit heat
The bottom and sides of the unit can heat up
during use and should not be touched. Burns may
result. Only connect or disconnect speaker cables
after the power supply has cooled down.
9. Moving the unit
When moving the unit, shut off power to all
connected equipment, and disconnect power
cords, connection cables, speaker cables and
other wires. Moving the unit while cables are
connected can cause damage to cables, fire or
electric shock. The unit is heavy and care should
be taken when unpacking, moving or lifting.
Manufacturing also creates sharp areas on the
unit; use thorough care in handling.
*Because the volume knob can be separated
from the amplifier, never hold the volume knob
when moving the amplifier.
10. Power cord
Only use the power cord supplied and do not
bend, twist,modify it for repair, or pin it under the
unit. Heavy objects, heat or tension may also
damage the power cord and cause fire or electric
shock. When disconnecting the power cord from
an outlet, do not pull the cord. Pulling on the cord
can damage it and cause fire or electric shock. Do
not touch the power cord with wet hands. Do not
place the power cord near heating equipment and
do not use the unit. If the plug fits loosely in an
electric outlet or the plug or cord is hot. If the cord
is damaged, replace it as continued use may
result in fire or electric shock.
11. Unit plug
Insert the plug into an outlet all the way to its
base. Incomplete insertion can cause heat
production, and dust build-up can cause fire.
Contact with the prongs of the plug can also
cause electric shock.
Do not connect the unit to an outlet where the
connection is loose even when the plug is inserted
all the way to its base. Do not use the unit if the
plug is hot. Heat production can cause fire.
If dust or metal accumulates on or near the prongs
of the plug, wipe the plug with a dry cloth after
disconnection. Continued use may cause fire or
electric shock.
12. Danger signs
If you notice a strange noise, smoke, unusual
odour or other abnormal condition, shut off the
unit, disconnect the power cord from the outlet
and have the unit inspected. Continued use may
result in fire or electric shock.
13. Electric storms
During electrical storms disconnect the unit and
avoid contact with the antenna and power cord.
Lightning can cause fire, electric shock, and
malfunction.
14. Internal temperature rise
To avoid internal temperature rise when installing
the unit, leave space between the unit and walls
or other equipment. When installed in a rack or
similar fixture, leave a 10cm (4") or larger gap on
top and at sides since internal temperature rise
can result in fire. The unit is provided with
ventilation holes to prevent internal temperature
rise. Blockage of these holes decreases
ventilation and can result in fire. Note the
following.
*Do not place the unit in a poorly ventilated area
*Do not place the unit on carpeting or on bedding
*Do not obstruct the ventilation holes
*Do not tilt the unit or turn upside down
15. Extended non-use
If the unit is likely to be unused for an extended
period, shut off power and disconnect from power
supply.
16. Volume Adjustment
If abnormal noise is produced during play at high
volume, reduce the volume level. Distorted sound
can cause overheating of speakers and amplifier.
Before switching power supply on, set the
amplifier volume to minimum. Sudden, loud noise
can cause damage to hearing.
17. Connecting TV/other audio equipment
When connecting a TV or other audio equipment,
always shut off power, read the operating manual
for each device and follow the instructions for
connection. Use only designated cables.
Use of non-designated cables or extension cables
can cause heat production, burns, and fire.
18. Antenna
An outdoor antenna should be located away from
power lines.

Notes on Use
■Volume Setting
Before switching ON minimise the volume.
Sudden, large output can damage the
speakers.
■Volume Etiquette
To avoid disturbance in your neighbourhood,
enjoy your unit at an appropriate volume.
Remember that at night, even low volume
carries into surrounding areas.
Help to maintain a pleasant living
environment.
■Speaker Cord Connection
Always connect speaker systems with
power OFF.
If a speaker cable is inadvertently shorted,
the protection circuit in the amplifier will
operate, and audio output will stop
temporarily.
In this event, disconnect the power cord
from the outlet, correct the shorted area
and reconnect the power cord to the outlet.
■Power supply
This product is equipped with vibration
countermeasures and a tone-quality
adjustment and has been designed to
