The CP-800 Stereo Preamp Processor combines the functionality of a conventional analog preamplifier with that of a multi-input DAC having digital processing features. The single-box approach eliminates unnecessary chassis, circuitry and cables, which reduces cost, shortens the signal path and preserves signal quality. The CP-800’s processing capabilities allow performance-enhancing features like parametric EQ, tone control and bass management to be accomplished in the digital domain, preserving the resolution of signals in a way not possible with conventional analog-based systems.

This new preamp/processor architecture is supported by numerous proprietary Classé technologies. The highest performance is achieved via the CP-800’s USB inputs. Asynchronous techniques are used for both computer-based sources (rear panel USB Device connector) and Apple® portable devices (front panel USB Host connector). Galvanic isolation and a technique we call Single-Clock-Substrate extend the advantages of our Asynchronous USB solution, lowering noise and reducing digital jitter to the lowest possible levels. The result is a breathtakingly direct and immediate sound—a crystal clear view into the soundstage—as if you were in the recording studio with your amplifiers plugged into the mixing board.

An entirely new design employs Zero Volt Switching in a Switch Mode Power Supply with Power Factor Correction to deliver performance and value on a scale never before offered in a high-end preamplifier.

Details about this and other CP-800 technologies are available in the CP-800 White Paper. A more comprehensive description of its many performance-enhancing features is available in the CP-800 Brochure. A quick overview and specifications can be found in the CP-800 Data Sheet.
