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. 5 kVA toroidal power transformer and 20, 000 uF of filter capacitance to provide the high levels of power needed for some of today's more sophisticated speaker systems. The inherently low output impedance of the HCA-1201A easily maintains control of your loudspeakers even during demanding impedance variations. Unique circuit topology of the direct coupled HCA-1201A includes balanced JFET input transistors, bipolar drivers and ultra high current output devices. Additionally, there are no inductors or capacitors in the signal path. These design refinements reduce high odd-order harmonic distortion, improve overall clarity and preserve low-level musical details. Please take a few moments to read these instructions so that you may fully understand the capabilities of your new Parasound power amplifier. Unpacking Your HCA-1201A Carefully unpack your amplifier and remove all the enclosed accessories. These accessories include one 14 AWG AC cord, and this manual.
