IHCC (High-instantaneous Current Capability)

Hntmnt studies have shown that while reproducing dynamic
IlillSIC Signals the instantaneous impedances of nearly all
loudspeakers drop to lessthan one third ofthe nominal ratings
lhoso low instantaneous impedances typically require 3 to 6
tiiiitrs more current than an 8 Ohm reSistive load, Reduced
dynamic range and increased distortion will result if the amr
plilier cannot provide these higher currents For this reason,
iiriz PM650 inwas designed to provide 35 amperes of in-

lUItrawide Bandwidth

The bandWidth of this unit is exceptionally Wide and inde
pendent of negative feedback. This improvestransient accuracy
and phase linearity

lLow Negative Feedback

This unit has been designed to have low distortion and wide
handwrdth without high negative feedback. This further ime
proves its dynamic accuracy.

IDiscrete Component Circuitry

In order to achieve the above goals, all discrete electronic
iirriiiitiy has been employed. All available integrated Circuits
iiiultt not provide this high level of performance

lSophisticated Electronic Protection

Harman Kardon engineers developed a unique protection
systini that permits high instantaneous current to be driven
into speaker systems but protects the amplifier from

shun manned or damaged speakers and wires. This protection
system in no way limits amplifier output voltage or current

GENERALIN

Always Use the Correct AC Voltage

Always connect the power cord to a domestic mains outlet.
Never connect the unit to an outlet supplying a higher voltage.
This may create a fire hazard.

NOTE FOR CUSTOMERS OTHER THAN CANADA

This unit is supplied With a voltage selector enabling selection
between 220V and 240V on the rear panel. If the selector is
not settothelocalvoltagesetthe selectortothe correctvoltage
with a screwdriver before connecting the power cord to a
mains outlet.

Handle the Power Cord Gently

.Do not disconnect the plug from the AC outlet by pulling
the cord. always pull the plug itself. Pulling the cord may break
the wire.

.If your unit Will be left unused for any considerable length
of time, disconnect the plug from the AC outlet.

.Do not place furniture or other heavy objects on the cord,
and avord dropping heavy objects on it. Also do not make a
knot in the power cord. Not only may the cord be damaged,
it can also cause a short circuit and a consequent fire hazard.

Place of Installation

Place your unit on a firm and level surface. Avoid installing
your unit under the followrng conditions.
b Moist or humid places.
>P|aces exposed to direct sunlight or close to heating
equipment.
> Extremely cold locations such as those in the direct draft
from an air conditioner
> Places subject to excessive vibration or dust.
> Poorly ventilated places.

Do not cover the ventilation slots on the top of the unit This
will cause the temperature inSide the unit to rise, which can
eventually affect the reliability of your unit.

Moving the Unit
Before moving the unit, be sure to unplug the power cord from

the AC outlet and disconnect the interconnection cords to
other units.

Do Not Open the Cabinet

To prevent fire or shock hazard, do not tamper With internal
components for inspection or maintenance. Harman Kardon
does not guarantee against performance degradation resulting
from any modification

If water a hairpin or Wire accidentally enters the unit. imme
diately unplug the power cord from the AC outlet to prevent
shock and consult an authorized Harman Kardon service sta-
tion If you use the unit under this condition, it may cause a
fire or shock hazard.

Cleaning
When the unit gets dirty, wipe it with a soft dry cloth. if "e.

cessary, wipe it with a soft cloth dampened with mild soapy
water and then wipe With a dry cloth.

Never use benzine, thinner, alcohol or other volatile agents,
and avoid spraying an insecticide near the unit.
