Introduction
Congratulations on your purchase of this precision audio component and thank you for your selection of
Parasound. Each part within your new Parasound power amplifier has been painstakingly selected for
optimum sound quality on even the most challenging music and film soundtracks. Parasound amplifiers
have greater operational flexibility and power than most other amplifiers you may have used, so please
take a few moments now to read these instructions thoroughly so you may fully understand the various
capabilities of your new Parasound power amplifier.
The Parasound HCA-1000A and HCA-750A are virtually identical in operation and very similar in sonic
performance. The main difference between these amplifiers is that the HCA-1000A has been certified
by Lucasfilm for use in THX Home Cinemas, while the HCA-750A has somewhat less power than
required to meet THX standards.
Unpacking Your Amplifier
Carefully unpack your amplifier and remove all the enclosed accessories including the remote control
and detachable AC cord. Be sure to inspect the unit for any possible shipping damage. If you see any,
contact your Parasound Dealer immediately. Be sure to save both cartons and the packing inserts for
future transport and always pack the inner carton into a protective outer carton before shipment.
Before you proceed, find the serial number located on the rear panel of your unit. Record it here for
future reference. ____________________
Installing and Rack Mounting Your Amplifier
Place your amplifier away from heat sources such as air ducts or 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.
Both the HCA-1000A and HCA-750A occupy two rack spaces (3 1/2") into 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 prevent ground loops. A wide variety
of rack mounting hardware is available from Middle Atlantic Products whom you can call at
(201) 839-1011. When rack mounting equipment, it is always a good idea to have someone help support
the unit while you bolt it to the rack rails.
Ventilation Requirements for Your Amplifier
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 Parasound 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. In either case, 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, you must use a fan to circulate the warm air that quickly becomes trapped
between them.
