The Home Theater Standard 7.1 is THX Ultra
certified and is fully compatible with the lat-
est surround processing modes, including
THX Surround EX, Dolby Digital EX,
DTS ES 6.1, DTS NEO:6, and Dolby Pro
Logic II. Additionally, Krell Music Surround
modes provide enhanced reproduction of
conventional stereo music sources.
The digital surround engine features state-of-
the-art signal processors, operating at high
speed and upsampled 24-bit precision, aug-
mented by 8MB of added memory. The
resulting boost in processing efficiency
improves bit stream recognition and channel
steering. Digital crossover circuitry,
offering a wide range of crossover fre-
quencies, operates in 48-bit double-
precision mode for unparalleled
ability to optimize speaker/subwoofer
system performance.Finally, all chan-
nels are processed by 24-bit/192 kHz
DACs, yielding the most accurate
analog signal possible.
HTS 7.1
Home Theater Standard 7.1
Surround Preamp/Processor
The Krell Home Theater Standard 7.1
is a full
system control center offering exceptional
audio and video performance, flexibility, and
ease of use. It is the centerpiece in Krell’s
HEAT™—High End Audio Theater—system
concept, which applies the fundamental prin-
ciples of Krell audio engineering to the cre-
ation of a fully integrated high-performance
multichannel audio/video system. Krell HEAT
makes it possible to enjoy movies at home
with audio quality unmatched by even the
finest commercial theater venues.
The analog circuitry—the most critical stage
in a surround preamp/processor—features the
advanced signal path developed for Krell’s
flagship stereo preamplifier, the Krell Current
Tunnel. All eight channels employ fully bal-
anced Krell Current Mode™ topology in a
zero-feedback configuration, delivering a
staggering 1MHz bandwidth. This circuitry
assures the most transparent reproduction of
today’s most demanding
movie soundtracks and
high-resolution audio
formats. In Preamp
mode, the HTS 7.1
operates as a pure
analog preamplifier,
bypassing all digital
ciruitry to ensure the
cleanest, most direct
signal path.
Broadcast-quality all-discrete
video circuitry, providing
bandwidth greater than
80MHz, delivers the most
vivid color and detailed pic-
ture with all input signals—
including composite, S-video,
interlaced component, and
progressive and wideband
High Definition.
With its powerful configuration
versatility and unparalleled sys-
tem interface and flexibility, the
HTS 7.1 is easy to use. Built-in
step-by-step guides simplify
optimal setup.
Krell’s 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,s shape, and level for all
seven channels. This makes it possible to program, for
example, independent settings for stereo music, multi-
channel 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.
Controls include bidirectional RS-232 communications,
12V triggers, and direct RC-5 input. The HTS 7.1 is also
Crestron I
2
P certified for use with touchpanel-based sys-
tems. The operating system resides in FLASH memory,
enabling software upgrades via the RS-232 port.
