Amplifier Precautions

Before using the PA-MC5500 power amplifier, be sure

to read the page above entitled Important Safety Instruc-

tions and this page of Amplifier Precautions.

While using the PA-MC5500, the internal temperature

will fairly rise. Excessive temperature rise may affect the

amplifier performance. To prevent damage from occur-

ring due to high internal temperatures, it is vital to have

proper ventilation and passage of air to carry out the heat

and keep the internal temperature within acceptable

ranges.

Caution

• Do not place the PA-MC5500 inside cabinets or clos-

ets where there is poor passage of air and ventilation.

• Do not place the PA-MC5500 near external heat

sources such as heaters or hot air ducts.

• Do not place other components or object on top of or

under the PA-MC5500.

• The cover of the PA-MC5500 contains ventilation

holes to allow the passage of air. Do not cover or block

these holes in any way.

If you are planning to place it within a cabinet, either

open holes in the rear panel of the cabinet to improve

ventilation or use a fan to force air circulation.

As a general rule, if during idling the cover is too hot to

touch, then ventilation needs to be improved.

Make sure that the floor or cabinet or rack where it will

be located is strong enough to support its weight.

You will also need to leave enough space behind the

PA-MC5500 to allow room for the power cord and other

cables for connecting system components. A minimum

of four inches is required behind the PA-MC5500 to

allow room for the cables and cords without excessively

bending them.

Do not place the PA-MC5500 near TV or radio. This

may cause noise or instable video on radio or TV respec-

tively.

Do not use a power cord other than the one supplied with

the PA-MC5500. The power cord supplied is designed

for use with the PA-MC5500 and should not be used with

any other device.

Be sure to only use wall sockets that properly fit the plug

of the power cord. If the socket does not match the plug

of the power cord, you will need to prepare an adapter.

Always use an adapter that is properly certified for this

application.

Connected speakers should have an impedance of

4 ohms or greater.

If speakers with an impedance of less than 4 ohms are

connected, it may damage the PA-MC5500.

From time to time you should wipe the front and rear

panels and the cabinet with a soft cloth. For heavier dirt,

dampen a soft cloth in a weak solution of mild detergent

and water, wring it out dry, and wipe off the dirt. Follow-

ing this, dry immediately with a clean cloth. Do not use

rough material, thinners, alcohol or other Chemical sol-

vents or cloths since these could damage the finish or

remove the panel lettering.

Whenever performing maintenance on the PA-MC5500,

any of its supplied accessories, or any device connected

to it, do not use solvents or cleaners of any kind that are

inflammable or combustible.

When you clean the input/output terminals on the rear

panel, do not use contact restorer. Doing so may cause

resin deterioration.

Below is a list of actions that you should never perform.

• Do not use the PA-MC5500 as a broadcast system or

musical instrument amplifier.

• Never use a generator, DC/AC converter, AC/AC con-

verter, or transformer to supply power for the

PA-MC5500.

• Never perform a “thumb test” (checking whether cur-

rent is reaching the lead wire on the hot end of the

input by touching it with your fingers) on the ends of

the input jacks or input cables.

Doing so may damage the speakers.

• Do not short across the output terminals or across the

output terminals and rear panel.

• Never remove the cover of the PA-MC5500.

• Do not install the PA-MC5500 in a location within the

reach of small children.

During lightning storm, never touch the power cord, plug

or cover of the PA-MC5500, and any devices connected

to the PA-MC5500.
