Product Details

Classe Sigma SSP Surround Sound Preamp/Processor, Model FC04995

The Sigma SSP is a 7.1 channel preamp/processor optimized for stereo but including HDMI switching, multichannel processing and bass management. Its wide variety of input connectors includes asynchronous USB and Ethernet for streaming, augmented by coax and optical; balanced and single-ended analog inputs plus an optional phono stage show how versatile this preamp/processor is despite its compact size. A host of performance-oriented features including digital domain tone/tilt control, and nine-band per channel parametric EQ ensure the best performance with each recording in every room.
