O W N E R ' S  M A N U A L

Congratulations on your purchase of this precision audio component and thank you for your selection of
Parasound.  Your HCA-1206 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-1206 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-1206

The HCA-1206 is packed in two strong cardboard cartons.  To unpack the amplifier, open both cartons
and carefully remove the HCA-1206 from its inner carton.  You may use its rear handles to facilitate
removal from the carton.  Take care not to cut or scratch yourself on the exposed extruded metal
heatsinks on either side of the unit.  Save your cartons and the packing inserts for safe transport in case
you move or if the unit ever requires shipping for repair.  Due to the massive weight of the HCA-1206,
the inner white printed carton is not strong enough for safe shipping by itself.  You absolutely must
place it into the additional outer over-carton before shipment.

The audiophile grade AC cord is packed separately in the carton.  This is the only cord we recommend
for use with your HCA-1206.  Please do not lose it.  Before you proceed, find the serial number which is
located on the rear panel of your unit and record it here for future reference or in case of casualty loss or
theft: _____________
