Parasound HCA-2205A Manual Do Utilizador

-5-

Congratulations on your purchase of this precision audio component and thank you for your selection
of Parasound. Your Parasound power amplifier was designed by renowned circuit designer John Curl
to meet or surpass the stringent standards required by Lucasfilm for use in THX Home Cinema
systems. Please take a few moments to read these instructions so that you may fully understand the
capabilities of your new Parasound power amplifier.

Carefully unpack your amplifier and remove all the enclosed accessories. Be sure to inspect the unit
for any possible shipping damage. If you see any, contact your Parasound Dealer immediately. Save
all the packing material in case you need to ship the amplifier for repair. Before you proceed, find the
serial number located on the rear panel of your amplifier and record it here for reference:

Locate your amplifier away from heat sources such as air ducts and radiators. Always mount the
amplifier horizontally and make sure that your cabinet or shelf can support its weight. It is best to
provide a separate shelf for your amplifier rather that stacking it directly above or below your other
components.

The HCA-2205A occupies four rack spaces (7") in a standard 19 inch equipment rack. Be sure to use
heavy duty mounting bolts to and nylon shoulder washers on both sides of the faceplate to avoid
scratching the amplifier’s front panel and also to help prevent ground loops. Contact Middle Atlantic
Products at (201) 839-1011 to obtain any rack mounting hardware you may need. When rack
mounting the HCA-2205A, have someone help support the unit while you bolt the component to the
rack rails.

To insure safe and reliable operation, it is very important that the amplifier has plenty of ventilation to
prevent overheating and automatic shut down from its thermal protection circuitry. Please observe the
following ventilation guidelines when installing your amplifier in a cabinet or other enclosed area:

1)  If you are not using a fan, allow at least six inches on each side and above the amplifier, and do not

close off the front with a cabinet door or panel.

2)  If you are enclosing the amplifier within an equipment cabinet, use a fan to draw in cool air and

exhaust warm air. Two vent holes are required: one for intake and one for exhaust.

3)  Do not place the amplifier on carpeting that will obstruct the air flow into the bottom of the

amplifier chassis and heatsinks.

4)  Avoid stacking components. If you do stack components, you must use a fan to circulate the warm

air that will quickly become trapped between them when they are powered on.
