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.
