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.

Ventilation

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.

Installation location and space

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.

Power cord

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.

Speakers

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.

Care

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.

Other

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.

Lightning storms

During lightning storm, never touch the power cord, plug or cover of the PA-MC5500, and any devices connected to the PA-MC5500.

Power
