FIDELITYDelta PRE is the foundation of your perfect system. Designed to connect to a range of sources, Delta PRE will extract the highest performance from every recording, whether analog or digital. Pre-amplifiers provide clean and controlled signals to the power stage. Both precision and perfection are required, and are delivered by Delta PRE. Network, USB, AES EBU, coax and optical inputs with optional HDMI XLR and RCA inputs Short signal paths to minimise signal interference Custom-made Navcomfeet absorb and reduce vibrations High-performance onboard MC MM Phono stage supports up to two phono inputs Rhodium-plated connectors for excellent and secure contacts CONTROLAudiophiles, recording professionals and equipment reviewers trust Classe amplifiers as a source of sonic truth. Delta Series allows listeners to experience that truth in their own homes. Every detail of the Delta Series is perfected by hand in our unique production facility in Japan to deliver powerful, natural, expansive sound with minimal noise or distortion. 0.25dB volume step precision to find your perfect sound level Digital domain tone control with Delta PRE Tilt control Support for mono or stereo subwoofers for better control of bass Selectable frequency and slope control Advanced five-band digital domain parametric equalization Digital bypass mode available to all analog sources Pass thru mode DESIGNAs the component you re most likely to touch, the design of Delta PRE matches its exceptional acoustic performance. Any interacting with Delta PRE is pure pleasure, from the superb cool-to-the-touch materials, to the precise tactile feedback of the volume control. Touchscreen control reflects Delta PRE s outstanding capability : pure analog clarity, advanced digital precision, confident, capable power and expressive sound.
