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
