Introduction
Krell KAV–280cd 1
READ THIS FIRST
Do not press the power button or power key until initialization is com­plete.
When you plug the AC power cord into the wall socket, the red stand-by LED illuminates. After a 30-second delay, the init LED (12) illuminates, indicating that the initializing is complete. You can now switch to the operational mode.
Off
When the AC power cord is unplugged from the AC power source, the component is off.
Stand-by Mode
When the KAV–280cd is connected to AC power, 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 power button on the front panel or pwr key on the remote control is pressed and the blue power LED illuminates, the compo­nent is in the operational mode and ready to play music.
Krell Current Mode
Aproprietary 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.
Definition of Terms
2 Krell KAV–280cd
OPERA TION
TECHNOLOGY
Following are the definitions of key terms used in your owner’s refer­ence manual.
Balanced
Asymmetrical 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 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
Atwo-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 recommended for connec­tions requiring long cable runs.
INPUT AND OUTPUT CONNECTIONS

4 Krell KAV–280cd
Before you install the KAV–280cd into your system, review the following guidelines to choose the location for the KAV–280cd. This will facilitate a clean, trouble-free installation. The KAV–280cd does not require any type of special rack or cabinet for installation. For the dimensions of the KAV–280cd, see Specifications, on the back cover.
Place the KAV–280cd on a firm, level surface, away from excessive heat, humidity, or moisture. The KAV–280cd requires at least two inches (5 cm) of clearance on each side and at least two inches (5 cm) of clearance above and below the component to provide ade­quate ventilation. Installations inside cabinetry may need extra venti­lation.
Do not place the KAV–280cd near hum sensitive components such as preamplifier phono stages or turntables. Although the KAV–280cd is well shielded, placing it near these components could create inter­ference and cause hum.
The KAV–280cd has superb regulation and does not require a dedi­cated AC circuit. Avoid connections through extension cords or multi­ple AC adapters. High quality 15 amp grounded AC strips are accept­able. High quality AC line conditioners or filters may be used if they are grounded and meet or exceed the unit’s power supply rating of 100 VA.
Placement
The KAV–280cd incorporates an advanced suspension system and does not require additional mass coupling or isolation. You may experiment with feet or cones as long as they are not permanently affixed to the unit. Any unauthorized modifications to the unit or electronics will void the warranty.
Do not attach enhancement accessories such as rings, mats, or dampers to individual compact discs. These accessories may interfere with the compact disc transport, resulting in erratic playback and/or poor sound.
