Your HCA-1500A 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. Each precision component within your HCA-1500A is carefully 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. 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. The HCA-1500A occupies three rack spaces (5 1/4") 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. Call Middle Atlantic Products at (201) 839-1011 to obtain information about a wide variety of rack mounting hardware. When mounting equipment into an equipment rack, 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. -4- Making Connections to Your Amplifier Leave the AC cord disconnected before making any signal or speaker connections. When making connections to the amplifier, make sure there is no strain or tension on the input leads, speaker wires, or AC cord that could cause them to pull loose. Input Connections Connect the output of your preamplifier or processor to the right (red) and left (white) channel RCA jacks for stereo operation. For bridged mono operation, use only the right channel input jack and leave the left channel jack disconnected. Output Looping Connections The right (red) and left (white) channel output looping RCA jacks provide you with a convenient way to connect multiple amplifiers together from one source for multi-room/multi-zone applications.
