DTS Digital Surround ™ is a discrete 5.1 channel digital audio format available on CD, LD, and DVD software 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 player, 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.

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 soundtrack 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 proprietary 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 understanding of these details helps ensure satisfactory operation of
and long life for your Showcase Processor and related system components.
Introduction
2 Krell Showcase Processor
Following are the definitions of key terms used in your owner’s reference manual:
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 installations, balanced connections have 6 dB more gain than single-ended connections and allow the use of long interconnect cables. Balanced connections are 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 connections 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 regulator 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 application 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 channel 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 pictures. 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.

47 Component Video Inputs
The Showcase Processor is equipped with three sets of component
video inputs.
On-screen display (OSD) is not available for progressive component video.
OSD is available for interlaced component video.
48 Comm Port RS-232 Connector
The Showcase Processor is equipped with an RS-232 communication port, which allows you to send operational instructions directly to
the Showcase Processor using an external computer control system.
49 RC-5 In
The RC-5 input makes custom installation easy and secure by
accepting baseband RC-5 input commands from hardwired remote
controllers.
50 12 VDC In and Out
The 12 VDC output sends a 12 Volt power on/off signal to other Krell
components via a 12 V trigger cable, as well as to other devices that
incorporate 12 Volt power on/off trigger input. The Showcase
Processor has four programmable 12 Volt outputs and one input.
When the Showcase Processor is in the operational mode and a trigger is
enabled, the 12 VDC Out provides 12 V of DC output. When the Showcase
Processor is in the stand-by mode or off, or if a trigger is not enabled, the
DC output is 0 V.
