Amplifier
Showcase Multichannel 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.
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.
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.
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.
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 compo-
nents, surface mount technology makes possible the
high circuit density required for the widest possible
dynamic range and bandwidth.
Easy Upgrades:
Amplifier modules
for the sixth and
seventh channels
can be added at
any time.
