Introduction Congratulations on your purchase of this precision audio component and thank you for your selection of Parasound. Your Parasound HCA-1201A High Current Mono-Block Power Amplifier was built using only the finest precision components available for optimum musical quality and performance. The HCA-1201A High Current Power Amplifier has a 1.
Making Connections to the HCA-1201A Refer to Drawing on Page 4 Leave the AC cord disconnected before making any signal or speaker connections. When making connections to the amplifier, make sure there is no strain or tension on the input leads, speaker wires, or AC cord that could cause them to pull loose. Unbalanced Input Connect the unbalanced outputs of your preamplifier to the RCA input jack.
Remote DC Trigger Connection The Remote DC Trigger allows you to turn on your amplifier with an external DC voltage source that ranges between + 9 Vdc to +12 Vdc. To properly terminate the DC trigger cable for the HCA-1201A, first determine the + DC voltage and ground conductor from the external DC source. For example, the Parasound AVC-2500 has a DC trigger that incorporates a two-conductor 1/8" mini connector. The tip of this connector is positive and the ring is negative (ground).
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.
