Congratulations on your purchase of this precision audio component and thank you for your selection of

Parasound. Your HCA-2200II was designed by one of the world's most renowned circuit designers, John

Curl. It is among the elite of the finest power amplifiers ever made. You have made an outstanding invest-

ment in your musical 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 later in this

manual to fully appreciate its considerable prowess.

Please take a few moments now to read these instructions thoroughly so you may fully understand the

sophisticated capabilities of your new Parasound HCA-2200II power amplifier.

Unpacking

The HCA-2200II is packed in two strong cardboard cartons. Save your cartons and the styrofoam inserts for

future safe transport in case you move or the unit ever requires shipping for repair. Note, the inner printed

carton is not itself strong enough for safe shipping, so you absolutely must place it into the additional outer

"overcarton" before shipment.

To remove the unit, you may use the handles at front and rear to balance its weight. You may findit easier if

you first rest the unit on its rear handles so you can change your grip before moving it to its correct horizon-

tal position. Take care not to cut or scratch yourself on the exposed extruded metal heatsinks on either side

of the unit.

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 the HCA-2200II. Please don't lose it.

Before you proceed, find the serial number which is located on the rear panel ofthe unit and record it here for

future reference or in case of casualty loss or theft:________________

Warning:To prevent fire or shock hazard, do not expose this unit to rain or moisture.

Placement of your HCA-2200II Keep your Parasound HCA-2200II out of direct sunlight and away from windows which could ever be left open to let in rain. It should be placed away from heat sources such as hot air ducts or radiators. Make sure your cabinet or shelf can support its weight! Do not place the unit directly on a pile carpet that could interfere with air flow into its bottom vent openings or heat sinks.

Speaker connections You may use bare solid or standard wire up to AWG 12, spade lugs, banana or dual banana plugs with the HCA-2200II "5-way" terminals. The 2nd pair of terminals is for bi-wiring (see below). If you use bare wire without spade lugs or plugs, make sure you strip only enough wire to fit into the hole that runs across the metal shaft of the terminal.
PAGE 5
Use good wire For best results you should never use speaker wire thinner than 16 gauge - it will constrict the sound and deteriorate bass response. You may also wish to experiment with audiophile-grade speaker wire and interconnects. Each will have a different characteristic sound and some may be more compatible with the sonic signature of your various components. Your HCA-2200II is unconditionally stable with any reputable brand of wire.

Operating the HCA-2200II Power Switch Press the upper side to turn the unit on; press the lower side to turn the unit off. Standby/Operation LEDs The red Standby LED will come on red whenever you first turn the unit on. It will light for about four to five seconds while the amplifier circuits are stabilizing before the protection relays disengage. At this time the red LED will turn off and the green Operate LED will come on to signal normal operation is available.
PAGE 7
In Case of Trouble Fuses The HCA-2200II has five external fuses which may blow as a result of an internal fault condition. This protects the unit from possible damage to internal parts. Never replace any fuse with a larger value. Substitution of a larger fuse may create serious stress or damage to internal parts and will void your warranty.

Parasound HCA-2200II Product Advisory Your Parasound HCA-2200II uses a grounded AC cord. For most systems, this will give optimum performance. However, with some systems a 60Hz hum may be audible. (50Hz overseas) This does not indicate a fault with the HCA-2200II It often happens with the most expensive high-end components that are equipped with grounded AC cords.
