Introduction to the KRELL S-1200/ 1200U
9S-1200/ 1200U
Thank you for your purchase of the S-1200/ 1200U Surround Sound Preamplifier/ Processor. Coupling legendary
Krell preamplifier technology, state of the art digital processing, and the latest in HDMI 1.3 surround formats, the
S-1200 is an ideal centerpiece for any high performance music and home theater system. Based on award-winning
preamplifier technology, all eight S-1200U analog output stages are built to the same exacting standard and feature
balanced and single-ended cable connections. Only Krell designed preamplifier circuitry is employed within every
channel utilizing discrete current based Class A, direct coupled circuitry for the greatest signal purity and highest
bandwidth. Performance robbing op amps or integrated circuits are not used anywhere in the audio path. Preamp
mode bypasses all digital circuitry and routes analog stereo inputs directly to a balanced resistor ladder volume
control for ultimate music reproduction.
The heart of Krell surround sound preamp/processors is sound quality that is paired to the latest in surround
processing technology. The S-1200 includes the finest Krell audio and video engineering plus the latest in
connectivity technology, HDMI 1.3, to insure the ultimate home theater experience. The audio signal path is a direct
descendant of the Evolution 707 Reference Surround preamp/processor. The S-1200 also uses the same DSP engine
and 1080p video stage from the Evolution 707.
At the hub of the S-1200 digital signal processing is a pair of dual core 32 bit Crystal CS497004 DSP’s performing
1.8 giga operations per second. Digital signals are then routed to 24 bit ESS Sabre DACS.
Video content is treated to the same high performance engineering as the audio signals. All-discrete video circuitry
takes full advantage of the new Deep Color HDMI 1.3 specifications. Maximum color depth has been increased from
24 bits to 48 bits and bandwidth from 165MHz to 340 MHz. Full video transcoding converts composite, S-Video,
or component inputs to HDMI signals. Furthermore, the S-1200U model includes upconversion to a maximum of
1080p resolution. The S-1200 is a true “one connection solution” with on-screen display, configuration menus, and
status messages available from all active video outputs including HDMI.
