Definition of Terms

 

Following are the definitions of key terms used in your owner’s ref-

 

erence manual.

INPUT AND OUTPUT

Balanced

CONNECTIONS

A symmetrical input or output circuit that has equal impedance from

 

both input terminals to a common ground reference point. The

 

industry standard for professional and sound recording installations,

 

balanced connections have 6 dB more gain than single-ended con-

 

nections and allow the use of long interconnect cables. Balanced

 

connections are less susceptible than single-ended connections to

 

induced noise from the system or the environment.

 

Single-ended

 

A two-wire input or output circuit. Use care when using single-

 

ended connections as the ground connection is made last and bro-

 

ken first. Turn the system off prior to making or breaking single-

 

ended connections. Single-ended connections are not recommend-

 

ed for connections requiring long cable runs.

OPERATION

Off

 

When the AC power cord is not plugged into the wall, the red

 

stand-by LED is not illuminated and the component is off.

 

Stand-by Mode

 

When the AC power cord is plugged into the wall, the red stand-by

 

LED illuminates, indicating that the component is in the stand-by

 

mode. This low power consumption status keeps the audio and cir-

 

cuits at idle. Krell recommends leaving the component in the stand-

 

by mode when it is not playing music.

 

Operational Mode

 

From the stand-by mode, when the power button on the front panel

 

is pressed and the blue power LED illuminates, the component 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 the voltage domain.

 

This unique technology provides the component with exceptional

 

speed and a wide bandwidth.
