UNPACKING AND INSTALLATION
Congratulations on Your Purchase!
Your new high fidelity amplifier is designed to deliver
maximum enjoyment and years of trouble free service.
Please take a few moments to read this manual
thoroughly. It will explain the features and operation of
your unit and help ensure a trouble free installation.
Please unpack your unit carefully. We recommend that
you save the carton and packing material. They will be
helpful if you ever need to move your unit and may be
required if you ever need to return it for service. Your unit
is designed to be placed in a horizontal position and it is
important to allow at least two inches of space behind
your unit for adequate ventilation and cabling
convenience.
To avoid damage, never place the unit near radiators, in
front of heating vents, in direct sunlight, or in excessively
humid or dusty locations. Connect your complementary
components as illustrated in the following section.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION : TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.
This symbol is intended to alert the user to the
presence of uninsulated "dangerous voltage"
within the product's enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.
This symbol is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
WARNING
To reduce the risk of fire or electric shock, do not expose
this appliance to rain or moisture.
Caution : Do not block ventilation openings or stack
other equipment on the top.

FOR U.S.A
FCC INFORMATION
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may
cause harmful interference to radio communications.
However, there is no guarantee that interference will
not occur in a particular installation. If this equipment
does cause harmful interference to radio or
television reception, which can be determined by
turning the equipment off and on, the user is
encouraged to try to correct the interference by one
or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment
and amplifier.
Connect the equipment into an outlet on a circuit
different from that to which the amplifier is
connected.
Consult the dealer or an experienced radio/TV
technician for help.
CAUTION: Any changes or modifications in
construction of this device which are not expressly
approved by the party responsible for compliance
could void the user's authority to operate the
equipment.
Caution regarding placement
(Except for U.S.A. and Canada)
To maintain proper ventilation, be sure
to leave a space around the unit (from
the largest outer dimensions including projections)
equal to, or greater than, shown below.
Left and right panels: 5 cm
Rear panel: 10 cm
Top panel: 20 cm
FOR U.S.A AND CANADA .................................. 120 V
FOR OTHER COUNTRIES ........................ 115 V/230 V
FOR YOUR SAFETY
FOR YOUR SAFETY
Units shipped to the U.S.A and Canada are designed
for operation on 120 V AC only.
Units shipped to countries other than the above
countries are equipped with an AC voltage selector
switch on the rear panel. Refer to the following
paragraph for the proper setting of this switch.
Safety precaution with use of a polarized AC plug.
However, some products may be supplied with a
nonpolarized plug.
AC VOLTAGE SELECTION
This unit operates on 115/230 V AC. The AC voltage
selector switch on the rear panel is set to the voltage
that prevails in the area to which the unit is shipped.
Before connecting the power cord to your AC outlet,
make sure that the setting position of this switch
matches your line voltage. If not, it must be set to
your voltage in accordance with the following
direction.
CAUTION : To prevent electric shock, match wide
blade of plug to wide slot, fully insert.
ATTENTION : Pour eviter les choc electriques,
introduire la lame la plug large de la borne
correspondante de la prise et poussre jusqu’au
fond.
AC voltage selector switch
FOR CHINA, EUROPE AND AUSTRALIA ........ 220V/230V/240V
FOR YOUR SAFETY
Units shipped to China are designed for operation on
220 V AC only.
Units shipped to Australia are designed for operation
on 240 V AC only.
To ensure safe operation, the three-pin plug supplied
must be inserted only into a standard three-pin
power point which is effectively earthed through the
normal household wiring. Extension cords used with
the equipment must be three-core and be correctly
wired to provide connection to earth.
Improper extension cords are a major cause of
fatalities. The fact that the equipment operates
satisfactorily does not imply that the power point is
earthed and that the installation is completely safe.
For your safety, if in any doubt about the effective
earthing of the power point, consult a qualified
electrician.
PAN-EUROPEAN UNIFIED VOLTAGE
All units are suitable for use on supplies 230-240 V
AC.
AC 230 V
AC 115 V
Move switch lever to match your line voltage with a
small screwdriver or other pointed tool.

Do not plug the AC input cord into the wall AC outlet until all connections are completed.
Be sure to connect the white RCA pin cord to the L(left) and the red RCA pin cord to the R(right) jacks when making audio
connections.
Make connections firmly and correctly. If not, it can cause loss of sound, noise or damage to the amplifier.
If the electricity fails or the AC input cord is left unplugged for more than 2 weeks, the memorized contents will be cleared.
Should this happen, memorize them again.

• Usually SPEAKER A terminals are used for only a
pair of speakers. When you have another pair of
speakers, SPEAKER B terminals can be used.
• Never short-circuit the + and - speaker cords.
• Be sure to connect speakers firmly and correctly
according to the channel (left and right) and the
polarity (+ and -).
Note :
• For safe amplifier operation, use the speakers with
impedance of over 8Ω when you use only SPEAKER
A or B terminals and use the speakers with impedance
of over 16Ω when you use both SPEAKER A and B
terminals.

If a fault occurs, run through the table below before taking your amplifier for repair.
If the fault persists, attempt to solve it by switching the amplifier off and on again. If this fails to resolve the situation, consult
your dealer. Under no circumstances should you repair the amplifier yourself as this could invalidate the warranty.
