Single-ended

A two-wire input or output circuit. Use care when using single-ended connections as the ground connection is made last and broken first. Turn the system off prior to making or breaking single-ended connections. Single- ended connections are not recommended for connections requiring long cable runs.

OPERATION

Off

When the power switch on the back panel is placed in the down position and the blue power LEDs turn off, the component is off.

Operational Mode

When the power button on the front panel is pressed and the three blue power LEDs illumi- nate, the component is in the operational mode and ready to play music.

Stand-by Mode

A low power consumption status that keeps the audio and regulator circuits at idle. Krell recom- mends leaving the component in the stand-by mode when it is not playing 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.

Krell Sustained Plateau Bias III

A patented microprocessor control system that maintains Class A bias operation regardless of musical demand. Class A bias is the most accu- rate method used to amplify musical signals. The new Sustained Plateau Bias III software is featured in the Full Power Balanced X Series amplifiers and was developed from the algo- rithm utilized in the Master Reference Amplifier. Sustained Plateau Bias III maximizes an ampli- fier’s efficiency both in power consumption and heat generation.
