[. . . ] O W N E R ' S M A N U A L HC A-2003 High Current Multi Amplif ier L CAS LM L U C A S FF II L M ¤ ® Congratulations on your purchase of this precision audio component and thank you for your selection of Parasound. Your HCA-2003 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 part within your HCA-2003 has been painstakingly selected for optimum sound quality on even the most challenging music and film soundtracks. Please take a few moments to read these instructions so you may fully understand the capabilities of your new Parasound power amplifier. i Amplifier HCA-2003 High Current Mult LUCASFILM Current Overload Power CH 1 Operation Stand by CH 2 CH 3 Unpacking Your HCA-2003 The HCA-2003 is packed in two cartons.

Connect the center output of your processor to INPUT 2 of your first HCA-2003. Connect the right front output of your processor to INPUT 3 of the your HCA-2003. Connect the right surround output of your processor to INPUT 1 of your second HCA-2003. Connect the left surround output of your processor to INPUT 2 of your second HCA-2003. Connect the subwoofer output of your processor to INPUT 3 of your second HCA-2003. -4- Speaker Connections to the HCA-2003 Refer to Figure #1 Use Good Speaker Wire For best results, use 16 gauge or thicker speaker wire and keep its length short as possible. This will help maintain a high damping factor and avoid deteriorating bass response. Also, each channel should be connected with the same length speaker wire. You may wish to experiment with audiophile-grade speaker wire. Polarity It is important to observe correct speaker connection polarity to prevent phase cancellation. One side of each speaker wire will have some sort of mark on one conductor: either printing, a raised ridge on the insulation or a different color of conductor. This permits you to know which wire you had connected to the + and which to the -- speaker terminals so you can do the same at the power amplifier terminals. Five-Way Binding Posts The five-way binding posts on the rear panel of your HCA-2003 will accept banana or dual banana plugs, most high-quality 1/4" spade lugs, or up to AWG 12 bare solid or stranded wire. Banana Plugs Banana plugs offer the most convenient connection to the speaker terminals. They also have a large amount of surface to make contact with the speaker terminal. For these reasons, we recommend the use of banana plugs in most applications. However, you may want to use the "gas tight" connection provided by spade lugs or bare wire. Spade Lugs If you prefer to use speaker cable with spade lugs, make sure you do not permit the lug to rotate as the terminal is tightened. Do not overtighten the speaker terminal onto the spade lug. The Parasound limited warranty excludes terminals that are sheared off as a result of overtightening. Bare Wire If you use bare speaker wire without plugs, make sure you strip off only enough insulation so the exposed bare wire fits into the hole that runs sideways through the terminal's metal shaft. Before inserting the wire, twist all its strands tightly to prevent strays that could cause a short circuit. [. . . ] Notes: -7- Rewiring Your HCA-2003 for 220 V - 240 V 50 Hz Operation The HCA-2003 may be rewired for operation abroad. This involves changing the primary wires on the power transformer. Please refer this conversion to a skilled electronics technician to avoid personal injury or possible damage to the amplifier. There are hazardous high voltages present inside the chassis even after the power is turned off and the AC cord has been disconnected. [. . . ]
