Definition of Terms

Following are the definitions of key terms used in your owner’s refer­ence manual.

INPUT AND OUTPUT
CONNECTIONS

OPERATION

Balanced

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 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 recommended for connec-

tions requiring long cable runs.

Off

When power button on the front panel or remote control is pressed

and the blue power LED tums off, the component is off.

Operational Mode

When the power button on the front panel or remote control is

pressed and the blue power LED illuminates, the component is in
the operational mode and ready to play music,

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.

Placement

Before you install the KAV-250cd/2 into your system, review the
following guidelines to choose the location for the KAV-250cd/2. This

will facilitate a clean, trouble-free installation. The KAV-250cd/2 does

not require any type of special rack or cabinet for installation. For the
dimensions of the KAV-250cd/2, see Specifications, on the back

cover.

Place the KAV-250cd/2 on a firm, level surface, away from exces-

sive heat, humidity, or moisture. The KAV-250cd/2 requires at least
two inches (5 cm) of clearance on each side and at least two inches

(5 cm) of clearance above the component to provide adequate venti-

lation. Installations inside cabinetry may need extra ventilation.

Do not place the KAV-250cd/2 near hum sensitive components such

as preamplifier phono stages or tumtables. Although the

KAV-250cd/2 is well shielded, placing it near these components

could create interference and cause hum.

Note The KA V-250cd/2 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 warran~

IMPORTANT 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.

AC Power
Guidelines

The KAV-250cd/2 has superb regulation and does not require a ded-

icated AC circuit. Avoid connections through extension cords or multi-

ple AC adapters. High quality 15 amp grounded AC strips are accept-

able. 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.
