The basic function of the Krell
Master Reference Amplifier (MRA) is
to emulate a pure voltage and
current source and to provide a
super-
abundant amount of accurate power
into any impedance load, virtually
ensuring maximum performance
from every speaker system.
FEATURES
The Master Reference Amplifier continues the tradition of
excellence that began with the first Krell amplifier, the KSA-100,
in 1980. Shortly after its introduction the KSA-100 earned
reference status in the industry and was used as a benchmark
against which other amplifiers were judged. Since that time
several of Dan D'Agostino's other Krell designs--the KRS 100,
KRS 200, and Audio Standard models--have advanced to become
benchmark power amplifiers. Now the Master Reference Amplifier
delivers the highest levels of performance in subjective sound
quality and objective measurement performance.
Features that make the Master Reference Amplifier the largest
and most powerful amplifier include innovative technologies for
controlling the vast power the amplifier generates and for
handling CAST, developed by Krell for its unprecedented
accuracy of signal transfer.
The Master Reference Amplifier brings a new level of
performance to sound reproduction. Its tremendous power
(exceeding 1,000 W into 8 Ohms, 2,000 W into 4 Ohms, 4,000 W
into 2 Ohms, 8,000 W into 1 Ohm, and 16,000 W into .5 Ohm)
gives the listener the freedom to enjoy unconstrained sound
reproduction. The technological innovations that manage these
large amounts of power are transparent to the user.
The Master Reference Amplifier sets a new standard for output
drive, assuring that no matter how much power is needed, it will
always be available and appropriate. Crucial to managing this
power is software-based control, an onboard microprocessing
module unique to the Master Reference Amplifier. This
removable/interchangeable plug-in module, called a software
