Operating the HCA-1201A
Refer to Figure #1
Power Switch
Press the upper side to turn the unit on manually; press the lower side to turn the unit off.
Standby/Normal Operation LEDs
The red Standby LED will light when the amplifier is turned on either with the power switch or an external
DC trigger. It will stay lit about four to five seconds while the amplifier circuits stabilize. After that, the
red LED will turn off and the green normal LED will signal that the protection relays have switched off
and that the amplifier is ready to operate. The Standby LED will also light whenever there is a short circuit
or other fault that triggers the protection circuitry. This may indicate one of the following conditions: DC
present at the amplifier's input, a speaker impedance overload, a short circuited speaker line, or possible
internal fault. If this LED remains lit, remove power to the amplifier and check all connections. During
this time, the protection circuits should automatically reset. If the red LED stays lit after you reapply
power, contact your Parasound Dealer for further advice.
Maintaining Your HCA-1201A
Your HCA-1201A requires no periodic maintenance and has no user serviceable parts inside. To avoid
the risk of electric shock, do not remove the top cover. If necessary, clean the chassis with a soft cloth
moistened only with window cleaner or clear water. Never use solvents or abrasives.
Main Power Fuse
There is an external fuse located within the AC receptacle that may blow as a result of an internal fault
condition. This fuse protects the unit from possible damage to internal parts. Never replace this fuse with
a fuse of higher value than installed from the factory. Substitution of a larger fuse may create serious stress
and damage to internal parts and will void your warranty.
In Case of Trouble
Call your Parasound dealer who should be able to suggest simple diagnostic tests you can easily perform.
If you determine that your HCA-1201A should be serviced, Contact Parasound or an Authorized
Parasound Warranty Center for inspection and possible servicing.
Returning your HCA-1201A to Parasound for Service (USA Only)
If we determine that you should send your HCA-1201A to Parasound, you will need to obtain a Return
Authorization (RA) number. The RA number must be clearly marked on the outer carton only. Ship the
unit with adequate insurance and a copy of your purchase receipt inside to validate your warranty.
Warranty repairs will only be performed by Parasound or authorized warranty centers on sets where your
purchase receipt is from an Authorized Parasound Dealer or Parasound Reseller. Units purchased from
unauthorized dealers are not eligible for warranty repair. Units that arrive without an RA number, without
a suitable shipping carton or with evidence of improper internal packing materials may be refused. We
do not accept collect shipments. After repair under warranty, the unit will be returned to you via prepaid
common carrier within the Continental United States. In the case of a non-warranty repair, contact us and
we will advise you of the repair charges before you ship the unit to us. The same packing and Return
Authorization number requirements apply.
