Definition of Terms

The following are definitions of key terms used in this owner’s reference:

Inputs and Outputs

Balanced

A symmetrical input or output circuit that has equal impedance from both input terminals to a common ground reference point. The industry standard for profes- sional and sound recording installations, balanced connections have 6 dB more gain than single-ended connections and allow the use of long interconnect cables. Balanced connections are completely immune to induced noise from the system or the environment.

CAST and Evolution CAST

Krell Current Audio Signal Transmission, or CAST, is a proprietary Krell circuit tech- nology for connecting analog components, transmitting the audio waveform between components in the current domain rather than in the voltage domain. The speed and bandwidth provided by Krell CAST and its circuitry update, Evolution CAST, yield accurate, realistic music reproduction, enabling connected compo- nents to perform as if they are all part of a single circuit. CAST and Evolution CAST are balanced connections, and reject induced noise.

Single-ended

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

Operation

Off

When the power status indicator is not illuminated, the amplifier is off.

Stand-by

A low-power-consumption status that keeps the audio and power supply circuits at idle. The power status indicator is illuminated in red, when the amplifier is in stand-by mode. Krell recommends leaving the amplifier in stand-by mode when it is not playing music.

Operation

When the power button is pressed, and the power status indicator is illuminated in blue, the amplifier is in operational mode and ready to play music.
