Introduction to the KRELL Foundation Processor
Thank you for your purchase of the Foundation Surround Sound Preamplier/Processor. From decoding the latest lossless
audio formats, extensive digital switching, 3DTV pass-through, and more, the Foundation is fully compliant with the digital
age. Yet the 7.1-channel processor also features balanced audio outputs, automatic setup and room EQ, and Krell’s legendary
robust hardware. A slim new form factor exudes the Krell aesthetic, while allowing placement in smaller equipment racks.
The heart of Krell surround sound preamp/processors is sound quality that is paired to the latest in surround processing
technology. At the hub of the Foundation digital signal processing is a pair of dual core 32 bit Cirrus Logic CS497024 DSP’s
performing 1.8 giga operations per second. Digital signals are then routed to 32 bit ESS Sabre DACS.
Based on award-winning preamplier technology, all Foundation analog output stages are built to the same exacting
standard and feature balanced and single-ended cable connections. Only Krell designed preamplier circuitry is employed
within every channel utilizing discrete current based Class A, direct coupled circuitry for the greatest signal purity and
highest bandwidth. Performance robbing op amps or integrated circuits are not used anywhere in the audio path. Preamp
mode bypasses all digital circuitry and routes analog stereo inputs directly to a balanced resistor ladder volume control for
ultimate music reproduction.
In addition to 10 HDMI 1.4a inputs, the Foundation has 2 HDMI outputs, both of which feature Audio Return Channel.
With ARC, a display device is able to send audio back down the HDMI cable to the processor. This is benecial for those
with televisions with built-in web streaming capability like Netix or Pandora, so the streaming audio can use the full home
theater system instead of just the TV’s speakers.
The Foundation passes video signals directly without any video processing, ensuring bit-for-bit accuracy of the signal, up
to 1080p/60. However, to simplify cabling, setup, and use, there is full transcoding of the 2 composite and 3 component
analog video inputs to the HDMI outputs.
The Foundation includes a new Krell development - Intelligent HDMI switching. Intelligent HDMI switching is a
combination of circuitry and innovative software that optimizes HDMI operation. Various parameters including the monitor’s
electronic ID and source video resolution are stored in non-volatile memory. All 10 source inputs are always active so
source, channel, video resolution, and audio format changes are instantaneous. The Intelligent HDMI design provides the
fastest signal recognition possible.
Krell designed the Foundation with exibility and ease-of-use in mind, with extensive routing capability of the audio inputs
to the various outputs. During setup, the specic paths will be chosen based on how the user intends to use each source,
displays, and audio output channels.
The Foundation will allow owners to take full advantage of the best audio soundtracks available, with decoding of Dolby
Digital, Digital Plus, Dolby TrueHD, DTS, DTS-ES Discrete, Matrix, and DTS-HD Master Audio. In addition, a full suite of
post-processing modes are included, including Dolby Pro Logic IIx and DTS Neo 6. Krell’s proprietary surround modes,
Party, General Admission, Front Row, and On Stage, offer a different way to listen to favorite tracks.
The Foundation also features Krell’s Automatic Room Equalization System (ARES), to ensure the best possible performance
from every theater. ARES analyzes all the speakers in the system, their location, phase, and distance from each other, to
determine the best crossover frequency, delay, and more. In addition, ARES incorporates the acoustics of the room to
determine unique EQ curves for each of the 7.1 output channels. Unlike other room EQs, ARES can be programmed to only
adjust the troublesome low frequencies, leaving high frequencies unaltered.
To allow full integration into a home automation system, the Foundation has Ethernet control, RS-232, 4 12v triggers
(2@0.5A and 2@60mA), and RC-5.

Connecting the Foundation to Your System
The Foundation is equipped with 10 HDMI inputs, 3 component video inputs, and 2 composite inputs.
Video outputs include 2 HDMI outputs. Both HDMI outputs include Audio Return Channel. Audio Return Channel
transfers audio from a TV back to the Foundation processor allowing TV audio listening through your home theater
system. The TV must be equipped with Audio Return Channel functionality for this feature to work.
This section provides information about connecting the Foundation to your system.
Follow these steps to connect the Foundation 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 Foundation and all components. Separate AC wires from
audio cables to prevent hum or other unwanted noise from being introduced into the system.
The Foundation is equipped with balanced and single ended 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 single ended
connections. When level matching is critical, keep this specication 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
Foundation. The Foundation is equipped with four sets of single-ended analog audio inputs (S-1 through S-4) via
RCA connectors and one set of balanced analog audio inputs via XLR connectors.
The Foundation is equipped with three coaxial digital audio inputs via RCA connectors and three digital EIAJ
optical inputs via TosLink connectors. Connect the digital audio output of your source components to the digital
inputs on the Foundation.
The Foundation is equipped with a second audio zone. Two different sources may be played simultaneously,
including HDMI based audio sources which, are fed to the Zone 2 analog outputs.

Initial Setup
The Foundation processor features the Krell Automatic Room Equalization System (ARES) to assist in setting up the
Foundation for optimal performance. The ARES system includes two operations, the speaker setup portion and the
equalization portion. The speaker setup portion of ARES determines the array and position of each speaker in the
system. From there, ideal values for speaker crossover, delays relative to the listening position and sound pressure
levels are all set automatically.
The second half of ARES is equalization. ARES includes a sophisticated equalization system that calculates at
frequency response for the entire system. The equalization algorithm uses the previously calculated speaker setup
data and acquired room characteristics to provide the ideal frequency curves for the speakers in the system.
Individual speaker setup parameters may be edited after the ARES system completes its initial calculations. The ARES
equalization process may be run again after the edits have been made.
All conguration options are selected using the front panel display or via a web enabled device such as a PC or
tablet. The Foundation and the web enabled device must be connected to the same network to use a web enabled
device for setup.

Foundation Processor RS-232 Feedback
OVERVIEW
The Foundation Processor is equipped with a system that can report back its operational status via the RS-232 port. The
system reports it’s operational status by transmitting a block of status data. The block is congured as 18, 8 bit words. The
rst and last word always contains hexadecimal code 55 to facilitate message framing and synchronization. When the data
block is sent through an RS-232 port, each 8 bit word transmitted will also have 1 stop bit associated with it.
The Status can be activated in 2 ways. The rst way is to ask for status to be sent by sending the RS-232 command “STAZ”.
The second way is to enable auto status by sending the RS-232 command “ASTEZ”, Once this command is sent, the S-1200/
1200U will transmit a status block whenever the status changes. Auto Status is disabled by sending the RS-232 command
“ASTDZ”. Auto Status remains enabled until AC power is removed or turned off.
