Congratulations on your purchase of this precision audio component and thank you for your selection of
Parasound. Your HCA-1200II  is designed by John Curl, one of the world's most renowned circuit designers.
It is among the elite of the finest power amplifiers ever made. You have made an outstanding investment in
your musical and home theater pleasure for years to come.

Every part, every direct-coupled circuit, has been painstakingly selected for optimum musical quality on the
finest and most challenging music and loudspeaker loads. Take a look at the special features found near the
end of this manual to fully appreciate its considerable prowess.

THX Certification assures you of total compatibility with Lucasfilm THX® Home Cinema standards. Con-
venient switching permits two operating modes: as a two channel stereo amplifier or a single channel
monoblock amplifier.

The HCA1200II has greater operational flexibility and power than most other power amplifiers you may
have encountered, so please take a few moment to read these instructions thoroughly so you may fully
understand the sophisticated capabilities of your new Parasound power amplifier.

Unpacking

Your HCA-1200II  packed in two strong cardboard cartons. Save your cartons and the styrofoam inserts for
future safe transport 
in case you move or your unit ever requires shipping for repair. Note, the inner white
printed carton is not itself strong enough for safe shipping, so you absolutely must place it into the additional
brown outer "overcarton" before shipment.

The AC cord is packed separately in the carton. This is a specially selected audiophile grade cord and is the
only cord we recommend for use with your HCA-1200II. Please don't 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:_____________________________.
