Precautions for use
About the power cord support bracket
o This unit is very heavy, so take care to avoid injury during installation.
o Do not install this unit in a location that could become hot. This
includes places that are exposed to direct sunlight or near a radiator,
heater, stove or other heating equipment. Moreover, do not place it
on top of another amplifier or equipment that generates heat.
o Avoid locations that are subject to vibrations or exposed to exces-
sive dust, cold or moisture.
o This unit generates more heat than ordinary power amplifiers.
When installing it, install it by itself at least 20 cm (8") from walls
and other equipment.
If you put it in a rack, take precautions to prevent overheating by
using a rack with ventilation openings, for example, and leaving at
least 20 cm (8") open above the top of the unit and at least 10 cm
(4") open behind the unit.
o Do not install it face up or on its side.
o Place the unit in a stable location near the audio system that you
will use with it.
o DO NOT place anything, not even CDs, CD-Rs, LP records or cas-
sette tapes, on top of the unit. Doing so could cause damage.
o Do not put cloth on top of the unit or place the unit on top of
bedding or thick carpet. Doing so could cause the unit to over-
heat or damage it.
o Supply voltage to the unit that matches the voltage indicated on
the rear panel. If you are in any doubt regarding this matter, con-
sult an electrician.
o Do not move the unit during use.
o Do not open the body of the unit as doing so might result in
damage to the circuitry or cause electric shock. If a foreign object
should get into the unit, contact your dealer.
o When removing the power plug from an outlet, always pull
directly on the plug. Never pull on the cord itself.
o If a TV is turned on while the unit is on, static might appear on the
TV screen depending on the characteristics of the TV broadcast
signal. This is not a malfunction of the unit nor of the TV. If this
occurs, turn the unit off.
This unit includes a bracket to support heavy power cords, such as
the ESOTERIC 7N-PC9500 MEXCEL and 7N-PC7500 and 7N-PC5500
power cords.
Align it with the power cord being used and attach it, tightening the
screws securely.

Connecting speakers
Notes about speaker cables
o Use commercially-available speaker cables to connect the
speakers.
o Use the shortest speaker cables possible. The longer the cable, the
greater the resistance value and the more that damping performance is reduced. Moreover, length also increases impedance and
capacitance, degrading the sound quality of high frequencies.
o Use left and right speaker cables that have the same length.
How to connect speaker cables
Use commercially-available speaker cables to connect the + terminal
of the unit to the + terminal of the speaker and the − terminal of the
unit to the − terminal of the speaker.
o Use speakers with at least 4 Ω impedance.
o If the exposed tip of the core wire of a speaker cable contacts
another cord or terminal, a short could occur.
Never allow a speaker cable to short.
o Do not connect more than one amplifier to a speaker.
o Do not bundle connecting cables with power cords. Doing so
could cause noise.
When using bare wires
Loosen the cap, insert the core wire from above and tighten the cap.
o The insertion hole faces up.
Cross-section
o The maximum wire diameter that can be inserted is 4 mm (1/8").
V
The power plug should always be disconnected when connecting speaker cables.
When using banana plugs
Insert the plug into the opening on the front of the terminal.
o Keep the cap tightened when in use.
o Carefully read the instructions for the banana plugs that you are
using.
Notice about the European model
In accordance with European safety regulations, connecting banana
plugs to speaker terminals is not allowed on European models. The
holes into which banana plugs could be inserted have been covered
with black caps. Connect speakers using bare wires or spade lugs. If a
black cap should become separated from its terminal, return it to its
original position.
When using spade lugs
Loosen the cap, place the lug around the terminal from above or
below and tighten the cap.
o When using a spade lug to connect, use one with an external
diameter of no more than 13.5 mm (1/2") and an inside diameter
of at least 6 mm (1/4").
