This product complies with the EMC directive (89/336/EEC) and the low-voltage

directive (73/23/EEC).

The Home Theater Standard 7.1 must be placed on a firm level surface where it is

not exposed to dripping or splashing.

The ventilation grids on the top and bottom of the Home Theater Standard 7.1

must be unobstructed at all times during operation. Do not place flammable mater-

ial above or beneath the component.

Do not remove or bypass the ground pin on the end of the AC power cord. This

could cause radio frequency interference (RFI) to be introduced into your playback

system.

Before making connections to the Home Theater Standard 7.1, make sure the back

panel power switch is off. Make sure all cable terminations are of the highest quali-

ty and free from frayed ends, short circuits, or cold solder joints.

THERE ARE NO USER SERVICEABLE PARTS INSIDE ANY KRELL PRODUCT.

Please contact your authorized Krell dealer, distributor, or Krell if you have any

questions not addressed in this Owner’s Reference.

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.

Thank you for your purchase of the Krell Home Theater Standard 7.1

Surround Preamp/Processor.

The Home Theater Standard 7.1 surround preamp/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 Home Theater Standard 7.1 delivers unparalleled

music and cinema soundtrack reproduction through the use of a full

complement of advanced Krell technologies including Krell Current

Mode™, Smart System Setup™, discrete Class A, direct-coupled cir-

cuitry with balanced outputs, user-configurable input assignment and

system macros, main and remote zone control capability, the Krell

Digital Room Equalizer, and broadcast-quality video circuitry.

The Home Theater Standard 7.1 is THX Ultra certified and features

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

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

proprietary Krell Music Surround modes. The flexibility and modular

architecture of the Home Theater Standard 7.1 allows upgrades to

internal hardware and software for future surround sound formats

and design enhancements.

This owner’s reference manual contains important information on the

placement, installation, and operation of the Krell Home Theater

Standard 7.1. Please read this information carefully. A thorough

understanding of these details helps ensure satisfactory operation of

and long life for your Home Theater Standard 7.1 and related system

components.

Introduction

2Krell Home Theater Standard 7.1

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.

Multichannel (DB-25)

A balanced input or output circuit that allows for the simultaneous

connection of all audio outputs plus one 5 VDC (5 Volt trigger) via a

single cable. DB-25 inputs and outputs are becoming popular for

connecting an audio/video surround sound processor and power

amplifiers, simplifying the integration of the two components into your

system.

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 HTS 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 con-

trol, the blue power LED illuminates. The component is in the opera-

tional mode and is ready to play music.

OPERATION

Krell Home Theater Standard 7.1 3

Krell Current Mode

A proprietary Krell circuit topology in which the audio gain stages of a

component operate in the current rather than the voltage domain.

This unique technology provides the component with exceptional

speed and a wide bandwidth.

Krell HEAT

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

tion incorporated into Krell components to enhance multi-channel

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 multi-channel sources with audiophile sound quality, placing

the audience in the middle of a lifelike environment.

Component Video Signal

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

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

Component video signals may be interlaced or progressive:

Interlaced signals build screen content in two passes.

Progressive signals build screen content in one pass. This

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.

S-Video Signal

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

nals bypass television circuitry required by composite video, and

reduces video noise as well as cross-contamination of color and

black and white signals.

Composite Video Signal

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

information on one wire.

YCbCr (YPbPr)

One way to designate different color signals used in component

video. Y = the luminance signal, Cb = the blue minus luminance (B-

Y) signal, and Cr = the red minus luminance (R-Y) signal. The com-

ponent video color signals are also designated as YPbPr.

Note

Krell Home Theater Standard 7.1 5

Before you install the Home Theater Standard 7.1 into your system,

review the following guidelines to choose the location for the compo-

nent. This will facilitate a clean, trouble-free installation.

The Home Theater Standard 7.1 does not require any type of special

rack or cabinet for installation. For the dimensions of your Home

Theater Standard 7.1 see Specifications, on pages 80-81.

The Home Theater Standard 7.1 requires at least two inches (5 cm)

of clearance on each side and at least two inches (5 cm) of clear-

ance above and below the component to provide adequate ventila-

tion. In addition, the Home Theater Standard 7.1 requires at least

three inches (7 cm) of clearance between other connected compo-

nents. For installations inside cabinetry, extra ventilation may be nec-

essary.

The Home Theater Standard 7.1 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

Home Theater Standard 7.1.

The Home Theater Standard 7.1 should be used only with the power

cord supplied.
