DTS Digital Surround ™ is a discrete 5.1 channel digital audio format available on CD, LD, and DVD soft-

ware which consequently cannot be decoded and played back inside most CD, LD, or DVD players. For this

reason, when DTS-encoded software is played back through the analog outputs of the CD, LD, or DVD play-

er, excessive noise will be exhibited. To avoid possible damage to the audio system, proper precautions

should be taken by the consumer if the analog outputs are connected directly to an amplification system. To

enjoy DTS Digital Surround ™ playback, an external 5.1 channel DTS Digital Surround ™ decoder system

must be connected to the digital output (S/PDIF, AES/EBU, or TosLink) of the CD, LD, or DVD player.

Krell Showcase Processor 1

Thank you for your purchase of the Krell Showcase Processor.

The Showcase Processor serves as the centerpiece in a Krell

HEAT™—High End Audio Theater—system, which applies the

fundamental principles of Krell engineering to the creation of a fully

integrated high-performance multichannel sound system. The

Showcase Processor delivers unparalleled music and cinema sound-

track reproduction through the use of a full complement of advanced

Krell technologies including Smart System Setup, discrete Class A,

direct-coupled circuitry with balanced outputs, user-configurable input

assignment, and broadcast-quality video circuitry.

The Showcase Processor is THX Ultra certified and features THX

Surround EX, Dolby Digital 5.1, Dolby Digital EX, DTS-ES 6.1, DTS

NEO:6, and Dolby Pro Logic II processing, in addition to nine propri-

etary Krell Music Surround modes. This flexibility allows upgrades to

software via Flash memory for future surround sound formats and

design enhancements.

The owner’s reference manual contains important information on

placement, installation, and operation of the Krell Showcase

Processor. Please read this information carefully. A thorough under-

standing of these details helps ensure satisfactory operation of

and long life for your Showcase Processor and related system com-

ponents.

Introduction

2 Krell Showcase Processor

Following are the definitions of key terms used in your owner’s refer-

ence manual:

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 immune to induced noise from the system or the envi-

ronment.

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.

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 Showcase Processor 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 reg-

ulator 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

control, the blue power LED illuminates. The component is in the

operational mode and is ready to play music.

Krell HEAT

The Krell term HEAT, or High End Audio Theater, is a design applica-

tion incorporated into Krell components to enhance multichannel

home entertainment systems. A Krell HEAT system is an integrated

home theater system consisting of a state-of-the-art Krell

preamp/processor and matching amplifiers that reproduce two chan-

nel and multichannel sources with audiophile sound quality, placing

the audience in the middle of a lifelike environment.

Composite Video

An encoded video signal that transmits luminance (Y) and color (C)

information on one wire.

S-Video

Video signal that separately transmits the luminance (Y) and color

(C) components of the video signal using one wire.

Component Video

A video signal that uses three wires to convey luminance (Y), red

minus luminance (R-Y), and blue minus luminance (B-Y) signals.

Component video signals may be interlaced or progressive.

Progressive signals build screen content in one pass rather than the

two passes required for standard (interlaced) video. Progressive

technology eliminates motion artifacts and produces film-quality pic-

tures. Both your source and video monitor must be equipped with

progressive video technology to realize this advantage.

YPbPr

One way of designating color difference signals. Y = the luminance

signal, Pb = the blue minus luminance (B-Y) signal, and Pr = the red

minus luminance (R-Y) signal.

Note

Krell Showcase Processor 5

Before you install the Showcase Processor into your system, review

the following guidelines to choose the location for the component.

This will facilitate a clean, trouble-free installation.

The Showcase Processor does not require any type of special rack

or cabinet for installation. For the dimensions of your Showcase

Processor see Specifications, on pages 76-77.

The Showcase Processor 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. In

addition, the Showcase Processor requires at least three inches

(7 cm) of clearance between other connected components. For

installations inside cabinetry, extra ventilation may be necessary.

The Showcase Processor 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. Contact your authorized Krell dealer, distributor, or Krell before

using any devices designed to alter or stabilize the AC power for the

Showcase Processor.

The Showcase Processor should be used only with the power cord

supplied.
