HCA-2003 High Current Multi Amplifier
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.
Unpacking Your HCA-2003
The HCA-2003 is packed in two cartons. To unpack the amplifier, open both cartons and use the front
and rear handles to facilitate remove of the HCA-2003 from its inner carton. Be careful not to cut or
scratch yourself on the exposed extruded metal heatsinks on either side of the unit. Save your cartons
and packing inserts for safe transport in case you move or if the unit ever requires shipping. Due to the
weight of the HCA-2003, the white inner carton is not strong enough for safe shipping by itself. You
must place it into the additional outer carton before shipment. The audiophile grade AC cord is packed
separately in the inner carton. This is the only cord we recommend for use with your HCA-2003.
Please take the time now to find the serial number located on the rear panel of your unit. Record it here
for future reference or in case of casualty loss or theft:
