HCA-1206 High Current Multi Amplifier

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: _____________

Placement of Your HCA-1206 Place your HCA-1206 away from heat sources such as hot air ducts or radiators. Make sure that your cabinet or shelf can support its enormous weight. Always place your unit horizontally. Do not place your unit directly on a carpet whose pile could interfere with air flow into its bottom vent openings or heat sinks. If you place your HCA-1206 on the floor near your speakers, elevate it above the pile of the carpet.

Input Connections and Switch Settings for the HCA-1206 Refer to Figure #2 Six Channel Operation The six channel mode of your HCA-1206 can power the six speakers required for a complete home theater: Front left and right, surround left and right, center channel, and subwoofer. Connect each output from your surround processor to the corresponding input connector of your HCA-1206. If you are using your HCA-1206 in the six channel mode, we suggest the following progression of channel priorities.
PAGE 5
Multi-Zone Stereo Operation You can switch your HCA-1206 to reproduce a single stereo source through up to three pairs of stereo channels via input cables connected to channels 1 and 2 input jacks only. This permits a neater and less confusing hookup. It eliminates the requirement for two or four “Y” adapters in order to split your preamplifier’s single pair of stereo outputs to feed the 3 pairs of HCA-1206 power amplifier input jacks.
PAGE 6
Mono Bridging — Channels 3+4 and 5+6 When you bridge channels 3+4 and/or 5+6, your speakers are connected to the bridged channels differently. You bridge by using the red + terminals of the adjacent channel pairs only. Note that bridged connections are made horizontally rather than vertically and the upper red + terminals have separate markings for bridging. In the bridged mode, channel 4 (and/or 6) output is positive and channel 3 (and/or 5) output is negative.

Operating Your HCA-1206 Refer to Figure #2 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 six protection relays start to energize. At this time the red LED will turn off and the green Operate LED will come on to signal normal operation.
PAGE 8
Fuse The HCA-1206 has one external 15 ampere fuse which may blow as a result of an internal fault condition. This protects the unit from possible damage to internal parts. Never replace this fuse with a larger value. Substitution of a larger fuse may create serious stress or damage to internal parts and will void your warranty. In Case of Trouble If you suspect a problem with this unit, first recheck all your connections.
