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.

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.

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.
