State-of-the-art audio performance
meets high definition video processing
in a dual zone preamp/processor design
that knows no compromise.
The Evolution 707 Surround Preamp/Processor
custom all-aluminum chassis is available
in silver or black. |

The Evolution 707 has 8.4 channels of audio output
featuring 2 center channel outputs and 4 subwoofer outputs, for maximum
flexibility in system design. Two digital signal processors (DSPs), Crystal
CS497004s, are employed to perform all surround mode processing. The Evolution
707 supports Dolby Digital Surround EX, Dolby Digital 5.1, DTS 6.1 ES, DTS 5.1,
DTS NEO:6, Dolby Pro Logic II processing as well as Dolby TrueHD and DTS HD
Master Audio lossless surround formats over HDMITM 1.3, plus 9 proprietary Krell
Music Surround modes. Digital processing circuitry runs in double precision mode
at a word length of 64-bits for the most precise division of frequencies and
optimization of the system’s speaker/subwoofer combination. Twelve output
stages are fully balanced and feature Krell Current ModeTM
topology with 1.5 MHz of bandwidth for accurate reproduction of today’s
demanding movie soundtracks. Evolution CASTTM
outputs are supported for all 12 channels. Current audio signal transmission
(CAST) is a proprietary method of sending the audio signal between components in
the current domain, from a high
|
impedance transmitter to a low impedance receiver.
Krell components connected in Evolution CAST act together as an electrically
unified whole, free from the deleterious effects normally imposed by the
connecting cables. Preamp mode bypasses all digital circuitry and routes the
analog input, stereo or 7.1 multi-channel, directly to the volume control for
the purest path possible. Separate power supplies for digital and analog circuit
paths are linear designs and feature custom made, low-noise transformers and
robust regulation. Remote control options include bi-directional RS-232
communication, multiple 12 VDC triggers, and a direct RC-5 input.
The all-discrete analog video circuitry provides
pristine pass-through of all progressive and wideband high definition signals
including HDMITM. Inputs and outputs for composite, S-video, component, and
HDMITM 1.3 are supported. On Screen Display set-up and status is available on
all video outputs, all the time, including up-conversion to component and HDMI
progressive outputs. Any SD or HD video standard may be converted up to
1920 x 1080p at 60 Hz.
