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
