Krell Industries 7.1 Definition of Terms, Input And Output, Balanced, Connections, Single-ended

Definition of Terms

	Following are the definitions of key terms used in your owner’s refer-
	ence 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 indus-
	try standard for professional and sound recording installations, bal-
	anced connections have 6 dB more gain than single-ended connec-
	tions and allow the use of long interconnect cables. Balanced con-
	nections are immune to induced noise from the system or the envi-
	ronment.
	Multichannel (DB-25)
	A balanced input or output circuit that allows for the simultaneous
	connection of all audio outputs plus one 5 VDC (5 Volt trigger) via a
	single cable. DB-25 inputs and outputs are becoming popular for
	connecting an audio/video surround sound processor and power
	amplifiers, simplifying the integration of the two components into your
	system.
	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 connec-
	tions. Single-ended connections are not recommended for connec-
	tions requiring long cable runs.
OPERATION	Off
	When the power switch on the back panel is placed in the down
	position and LEDs turn off, the component is off.
	Stand-by Mode
	When the HTS is connected to AC power and the back panel power
	switch is in the up (on) position, the red stand-by LED illuminates.
	This indicates that the component is in stand-by mode, a low power
	consumption status that keeps the audio and regulator circuits at idle.
	Krell recommends leaving the component in the stand-by mode
	when it is not playing music.
	Operational Mode
	When the component is in the stand-by mode, and you press the
	power button on the front panel or the power key on the remote con-
	trol, the blue power LED illuminates. The component is in the opera-
	tional mode and is ready to play music.
