Full featured processor from Proceed (Mark Levinson) A few light scratches and scuffs as shown in our photos, but otherwise working perfectly. An excellent match to the Proceed HPA2 and HPA3 currently listed on our website for a very capable 5 channel home theater setup. (The HPA2 is a two-channel theater amplifier, and the HPA3 is a three-channel theater amplifier) Includes the processor, the original Proceed remote, and a power cord. Click here for a PDF copy of the Proceed AVP2 Owner's Manual From the Owner's Manual: The AVP2 shares the same type of powerful DSP engine used in the Mark Levinson No.40 Media Console, employing multiple Analog Devices SHARC DSP chips in a Madrigal-designed operating system. This DSP engine has sufficient power to handle the decoding requirements of Dolby Digital, DTS, MPEG2, THX, and many other decoding schemes. In addition, its power and flexibility provide for future updates to handle as-yet-undefined digital audio standards that may be adopted in the future, such as a secure digital interface for DVD-Audio or SACD (should the recording industry ever manage to agree on such a thing). The AVP2 includes eight channels of digital to analog conversion, all of whichcan process and convert 192 kHz digital information. In addition, all volume controls within the AVP2 are implemented in the analog domain, allowing the DACs to run at their maximum resolution at all times. (This approach stands in contrast to digital volume controls, which operate by requiring the converters to operate at less than their maximum capabilities. After all, what would be the point of having 24 bit/192 kHz music formats if you end up throwing away much of the improvement in a digital volume control?) Our Testing Process for Preamplifiers at SkyFi:We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline. At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching. Final testing involves putting actual music through the preamplifier We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage Kef speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
