The Evolution 222 brings the advanced technologies and inspired design of the
Evolution 202 to single chassis format. Often overlooked, the preamplifier is a
critical component in the signal chain. A small signal must be carefully
amplified without damaging the ephemeral staging and dimensional components of
the music.
Heard through the Evolution 202, music emanates from an expanse that outlines
the recording venue, transporting you to the moment of creation.
The Evolution 222 is the perfect companion for the Evolution 402 Amplifier
and Evolution 505 Source.
FEATURES
1.5 MHz open loop bandwidth in a zero feedback, balanced, Krell
Current Mode design terminating in Krell CAST.
All signal gain is realized in a surface mount topology using proprietary
multiple-output current mirrors with nearly 500 times the open loop linearity of
other designs.
Zero negative feedback is used anywhere in the preamp, nor is it necessary.
Open-loop distortion is typically less than 50 parts per million.
A complete Evolution (source, preamp, amplifier) system, connected in CAST,
reduces the number of voltage gain stages to the minimum, one. The resulting
noise floor is approaching the theoretical limit of technology.
The volume control is realized with a 16-bit balanced resistor ladder --
bandwidth and transient response of the preamp circuitry are virtually
unaffected by the volume setting.
150 VA toroidal transformer drives four 6-amp bridge rectifiers and 19,800
microfarads of filter capacitance.
Krell designed digital control circuit monitors and optimizes the
preamplifier's operating parameters.
