Description
Up for sale is a beautiful and POWERFUL Parasound HCA-1206 THX CERTIFIED 6 channel power amplifier. This amp puts out 135 Watts per Channel when run in 6 channel mode. Two pairs of channels can be bridged producing a whopping 350 Watts per Channel for the bridged channels!! This amp was from the original owner. I have thoroughly tested this amp and it is working perfectly. Cosmetically the unit is in excellent overall condition. There are a few minor scuffs on the top front edge and typical minor marks elsewhere. Here is information about the unit from HiFi Review: The Parasound HCA-1206, designed by the well-known circuit designer John Curl, is an exceptionally powerful and versatile high-performance power amplifier certified by Lucasfilm for use in Home THX surround-sound systems. It is also suitable for multiroom audio systems or any other application requiring as many as six independent high-power amplifiers.With all channels driven, each channel of the HCA-1206 is conservatively rated to deliver 120 watts into 8 ohms, or 180 watts into 4 ohms, from 20 Hz to 20 kHz with less than 0.07 percent total harmonic distortion (THD). Although all its channels are identical, Channels 1 and 2 are designed specifically for the front channels of a multichannel sound system and cannot be bridged. Channels 3 and 4 and Channels 5 and 6 can be switched to bridged mono operation, in which each bridged pair is rated at more than 300 watts into 8 ohms.Each output channel is rated for operation with loads as low as 4 ohms, although a pair of bridged channels should not be used with loads of less than 8 ohms. That limitation is not due to any lack of current-delivering ability for short intervals, but prolonged high-current operation could create excessive temperatures in the amplifier, which does not have an internal fan.The HCA-1206 is a large, very heavy amplifier, weighing more than 70 pounds. It is equipped with handles on the front and rear panels. The output circuitry is located along the inner sides of the cabinet, and exterior heatsink fins cover the full depth of each side. The heavy steel top cover is also extensively perforated for ventilation. The output stages use a total of twenty-four 60-MHz, 15-ampere output transistors in matched complementary pairs.A huge power transformer (which surely supplies a good share of the amplifiers weight) is located in the center of the HCA-1206 just behind the front panel. It is rated at 1.7 kVA (kilovolt-amperes), consistent with the amplifiers potential for delivering more than a kilowatt of clean audio power. Parasound says that the power supply contains more than 120,000 microfarads of computer-grade capacitors. Although the power supply and related components, plus the actual output transistors (four per channel), occupy most of the HCA-1206s interior, there is also a single fairly large circuit board containing the low-level amplifier stages and no fewer than fifteen fuses of various types.Numerous other circuit and construction features contribute to the unusual character of the HCA-1206. These include cascode Class A input stages, complementary MOSFET high-voltage drivers, and Class A/AB biased output transistors direct-coupled to the speakers without intervening phase-correcting networks. The amplifier also contains a number of temperature sensors and protective relays.The front panel is comparatively stark. Besides the two massive handles, there is a rocker-type on/off switch, an adjacent LED power light, and six LEDs to indicate instantaneous current overload in each of the six channels.The rear apron actually serves some of the functions usually allocated to a front panel. Six pairs of multiway binding posts, which accept stripped wires or banana plugs, are along the bottom, plainly marked to show their function. Channels 1 and 2 are labeled non-bridgeable, and the others are marked MonoBridge. Small toggle switches above Channels 3/4 and 5/6 are normally set down for separate channels, up for MonoBridge operation. Here are the specs from the Parasound site: John Curl brings his art to home theater with this award-winning amplifier.
