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 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 circuitry 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

2 Krell Home Theater Standard 7.1

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.

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 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 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 control, the blue power LED illuminates. The component is in the operational mode and is ready to play music.

Definition of Terms

INPUT AND OUTPUT CONNECTIONS

OPERA TION

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 application incorporated into Krell components to enhance multi-channel home entertainment systems. AKrell 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 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 (C) components of the video signal using one wire. The s-video signals 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 (BY) signal, and Cr = the red minus luminance (R-Y) signal. The component video color signals are also designated as YPbPr.

The Home Theater Standard 7.1 remote control provides on and off, input selection, processing mode selection, speaker volume and balance adjust, and mute functions, as well as access to the system configuration menu.

To send operational instructions directly to the Home Theater Standard 7.1 using an RS-232-based external computer control system, see RS-232 Port: Sending Commands and Interpreting Data, the developer’s reference for the Home Theater Standard 7.1.

The Home Theater Standard 7.1 remote control uses one CR2025 lithium battery, which is included with the shipment.

To open the battery compartment on the back of the remote control:

1. Place the remote face down on the table.

2. Use your thumbnail or a small jeweler’s or eyeglass screwdriver to move the small tab toward the center of the remote, while using your index fingernail or screwdriver to pull down gently on the slot to the right of the tab. The battery compartment will slide out.

3. Place the battery, plus side up, in the battery tray.

4. Slide battery compartment back into the remote until you hear a click.

The remote control is ready for operation.

Do not use a knife or other sharp objects to open the battery compartment; they will scratch the remote control finish.

Replace batteries when remote control function becomes intermittent. Remove batteries if the remote control is not to be used for a long period of

time. Battery leakage can damage the remote control.

CONNECTION STEPS

Connecting the Home Theater Standard 7.1 to Your System

22 Krell Home Theater Standard 7.1

This section provides information about connecting the Home Theater Standard 7.1 to your system. To expedite setup, please review Getting Started, on page 6, before following the connection steps below.

Follow these steps to connect the Home Theater Standard 7.1 to your system:

1. Make sure all power sources and components are off before connecting inputs and outputs.

2. Neatly arrange and organize wiring to and from the Home Theater Standard 7.1 and all components. Separate AC wires from audio cables to prevent hum or other unwanted noise from being introduced into the system.

The Home Theater Standard 7.1 is equipped with balanced, singleended inputs, and 7.1 inputs.

Krell recommends using balanced interconnect cables. Balanced interconnect cables not only can minimize sonic loss but also are immune to induced noise, especially for installations using long cables. Balanced connections have 6 dB more gain than singleended connections. When level matching is critical, keep this specification in mind. Krell recommends that you use balanced inputs for components that will use the preamp mode.

For stereo analog input sources, connect the right and left outputs of your source components to the inputs on the Home Theater Standard 7.1. The Home Theater Standard 7.1 is equipped with nine sets of single-ended analog audio inputs (41) (S-1 through S-7, tape, and VCR) via RCA connectors and one set of balanced analog audio inputs (35) via XLR connectors.

For multichannel analog sources (for example, multichannel SACD and DVD audio players), connect the outputs of your source component to the 7.1 inputs (42) on the back panel.
