HCA-2205A

About the HCA-2205A

The Parasound HCA-2205A is a 5-channel high current power amplifier offering 220 watts RMS per channel into 8 ohms and 300 watts RMS per channel into 4 ohms, all channels driven. It features independent power supplies for each channel, a massive encapsulated 2 kVA toroidal power transformer, and 30,000 uF power supply capacitance per channel. The amplifier uses cascode Class A input stages with matched J-FET pairs and hand-picked complementary transistors in the high voltage driver stage. It has 8 complementary pairs of 15 ampere 60 MHz output transistors per channel, direct-coupled to speakers without LRC networks, and DC servo direct-coupled audio circuits with 0.8 Hz rolloff. The unit operates in high-bias Class A/AB mode and includes multiple protection circuits, temperature sensors, and silver-cadmium relay protection. It has gold-plated metal structure RCA input jacks and comes with a handmade audiophile-grade AC power cord. The amplifier is THX certified and designed for high fidelity and home theater applications. It weighs approximately 85 lbs and measures 19" wide x 7" high x 19.5" deep (7 5/8" high with feet).
