A unique software-based seven-channel digital room
equalizer maximizes system performance in any room.
For each of four memory settings, the user can program
filter type (high-pass, low-pass, notch, peaking, and
high/low shelf), frequency, shape, and level for all seven
channels. This makes it possible to program, for exam-
ple, independent settings for stereo music, multichannel
music, movie surround, or even video game software.
Krell’s digital room equalizer can transform your family
entertainment room into a breathtaking home theater…
without hiring an architect.
Showcase Processor
With the latest in surround sound
technologies, a proprietary digital room
equalizer, and an exceptional preamplifier section, the Showcase processor
extends the KAV Series’ tradition of
Krell engineering and affordability to a
new generation.
State-of-the-art digital chipsets, operating with
upsampled 24-bit precision, control all of the digital
signal processing in the Showcase processor. THXUltra certified, the processor incorporates advanced
technologies, including Dolby Pro Logic II, Dolby
Digital EX, THX Surround EX, DTS NEO: 6, and DTSES 6.1. Krell software provides digitally controlled
bass management with user-selectable crossover
points, optimizing the system’s speaker/subwoofer
interface. Following all digital signal processing, the
information is decoded by 24-bit/192 kHz DAC’s in
all 7.1 channels to deliver the most accurate analog
signal possible to the preamplifier stage.
The Showcase processor employs fully
discrete video circuitry. With bandwidth
greater than 80 MHz, it ensures the
integrity of all progressive and High
Definition component signals, while still
providing the convenience of on-screen
display for all video signals.
The Showcase processor uses Krell advanced analog
circuitry in the critical preamplifier section. The fully
balanced design delivers the extremely wide bandwidth required for accurate reproduction of the current generation of movie soundtracks and high-resolution audio formats. The analog Preamp mode
bypasses all digital circuits, providing the most direct
signal path for multichannel and stereo recordings.
Advanced operating features include a host of remote user
interfaces, FLASH memory for future software upgrades, and an
intuitive menu-based Smart System Setup. From ease of initial
setup to dramatic performances in your home, the Krell
Showcase sets a new benchmark for high performance and
value in a preamp/processor.

Amplifier
Simply elegant, the refined brushed
aluminum Krellcoat™ finish only hints at the
exhilarating performance that lurks beneath
the exterior of the Krell Showcase
Multichannel Amplifier.
Every aspect, from sonic performance and power
delivery to style and upgradability, functions
in seamless harmony. Available in 5-, 6-, and 7-
channel configurations, the Showcase amplifiers are
solidly based on the same legendary Krell technolo-
gies found in any of its top-of-the-line- siblings.
Showcase Multichannel Amplifier
Featuring technology developed for the Full
Power Balanced amplifiers, the Showcase
design employs Krell Current Mode™ circuitry.
Its fully balanced topology ensures the lowest
noise and greatest detail retrieval. Class A input,
pre-driver, and driver stages provide the most
accurate signal path for critical low level signals.
The foundation of any amplifier is
the power supply. A massive
1,500 W toroidal transformer and
80,000 microfarads of filter capac-
itance provide a rock solid power
platform impervious to speaker
demand or AC line fluctuations.
Easy Upgrades:
Amplifier modules
for the sixth and
seventh channels
can be added at
any time.
The modular platform provides an upgrade path
for the Showcase 5 and Showcase 6 amplifiers,
enabling additional channels to be installed at
any time. The base platform includes input and
speaker connections for seven channels, making
upgrades a simple matter when desired.
To deliver the most electrifying experience with
today’s demanding multichannel music and movie
soundtracks, an amplifier must be able to generate
substantial power into 8 ohms… and then double
that output when a speaker’s impedance is halved
to 4 ohms. The Showcase amplifier module uses
eight high-speed power devices to deliver 125 W
into 8 ohms and 250 W into 4 ohms. Previously
implemented only in reference-level Krell components, surface mount technology makes possible the
high circuit density required for the widest possible
dynamic range and bandwidth.
