Preamplifier

Channel

Also termed preamplifier or preamplifier channel. A channel is one Evolution Two, comprised of one preamplifier chassis and one power supply chassis.

Right-terminated channel

Any right preamplifier channel that is last in a chain of linked Evolution preampli- fiers is referred to as right-terminated. There is only one RG-45 link cable connect- ed to a right-terminated channel.

Transmitter

Also termed transmitter preamplifier. The transmitter is a right-terminated preampli- fier channel that sends IR, RC-5, and RS-232 data to the other linked preamplifier channel(s), or receiver(s).

Receiver

Also termed receiver preamplifier. Receivers are linked preamplifier channels that receive IR, RC 5, and RS-232 data from a right terminated preamplifier channel, or transmitter.

Operation

Off

When the stand-by/power LEDs and the backlight grid are not illuminated, the pre- amplifier is off.

Stand-by

A low power consumption status that keeps the audio and regulator circuits at idle. The stand-by/power LEDs are illuminated in red, when the preamplifier chan- nel is in the stand-by mode. Krell recommends leaving the preamplifier in the stand-by mode when it is not playing music.

Operation

When the backlight is illuminated in blue, the preamplifier is in the operational mode and ready to play music.

Technology

Krell Current Mode

A proprietary Krell circuit topology in which the audio gain stages of a component operate in the current rather than voltage domain. This unique technology provides the component with exceptional speed, and a wide bandwidth.
