Amplifier Precautions
Before using the PA-MC5501 power amplifier, be sure to
read the page above entitled Important Safety Instructions
and this page of Amplifier Precautions.
While using the PA-MC5501, the internal temperature
will fairly rise. Excessive temperature rise may affect the
amplifier performance. To prevent damage from occurring
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-MC5501 inside cabinets or closets where
there is poor passage of air and ventilation.
• Do not place the PA-MC5501 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-MC5501.
• The cover of the PA-MC5501 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-MC5501 to allow room for the power cord and other
cables for connecting system components. A minimum of
four inches is required behind the PA-MC5501 to allow
room for the cables and cords without excessively bending
them.
Do not place the PA-MC5501 near TV or radio. This may
cause noise or instable video on radio or TV respectively.
Do not use a power cord other than the one supplied with
the PA-MC5501. The power cord supplied is designed for
use with the PA-MC5501 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-MC5501.
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.
Following this, dry immediately with a clean cloth. Do not
use rough material, thinners, alcohol or other Chemical
solvents or cloths since these could damage the finish or
remove the panel lettering.
Whenever performing maintenance on the PA-MC5501,
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-MC5501 as a broadcast system or
musical instrument amplifier.
• Never use a generator, DC/AC converter, AC/AC
converter, or transformer to supply power for the
PA-MC5501.
• Never perform a “thumb test” (checking whether current
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-MC5501.
• Do not install the PA-MC5501 in a location within the
reach of small children.
During lightning storm, never touch the power cord, plug
or cover of the PA-MC5501, and any devices connected to
the PA-MC5501.
