Overview

The "Krell Audio Standard" is a dual-chassis monoblock with a regulated power supply separated from the audio circuitry.

The regulated power supply features Krell's "Anticipator" circuit that senses input at a high speed of 1,800 V / μ a second and sets the bias, which avoids the reduction of instant dynamics that is typical of regulated power supplies. 

Krell's Sustained Plateau Bias system also monitors the input signal to determine the bias level required to maintain pure class-A operation, using five discrete bias levels, each equivalent to a class-A amplifier of increasing power capability, keep power consumption and heat dissipation to a minimum. The amp actually maintains the higher output level for 90 seconds before changing back to a lower level.

Produced in cooperation with Motorola, 48 TO-3 can-type output transistors, are each fed by 48 matching regulator transistors offer extremely stable voltage and current, even at 1 Ω load output.

The result is effortless power delivered against an almost unnoticeable background, obviously capable of driving the most demanding loudspeakers. Also, the backlit meters are a pleasure to enjoy in low light.
