CONFIGURATIONS

Theater Throughput

INPUT AND OUTPUT CONNECTIONS

OPERATION

Theater Throughput is a Krell configuration option that allows the signal from a surround preamp/processor to pass through a Krell preamplifier or integrated amplifier with no gain, for integrated vol- ume and balance management of Krell home theater systems.

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 professional and sound recording instal- lations, 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.

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 recom- mended for connections requiring long cable runs.

Off

The component is off when the AC power cord is unplugged from the wall receptacle.

Stand-by Mode

A low power consumption status that keeps the audio circuits at idle. When you plug the AC power cord into the wall receptacle, the red stand-by LED illuminates. The component is now ready to be switched to the operational mode. 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 control, the blue power LED illuminates. The component is in the operational mode and is ready to play music.
