Krell - Foundation Krell - Foundation
When we entered the home theatre market in 1996, we refused to compromise our standards. Our first surround-sound processor, the Krell Audio + Video Standard, elevated the expectations of home theatre aficionados around the world. No one else had attempted to create a surround processor that could compete with the finest two-channel preamps.
And to this day, no one else has achieved the level of performance you get in Krell surround processors. Borrowing circuitry, power supply design, and construction techniques from our best two-channel preamps, we achieve a level of transparency and sonic purity never thought possible in multichannel sound. We always incorporate the latest technologies including HDMI 1.4 compliance, to get the best performance from the ever-evolving standards of the home theatre industry.

Krell is a strong player in both the high-end stereo and home theater universes and it brought several new products catering to both camps for CEDIA 2013.  For home theater aficionados, though, the most exciting new Krell product was the upcoming Foundation A/V Preamp / Processor. 

Reviewers comments:
We are back from the NY Audio show and the reaction to our two systems was outstanding. Our home theater system included the Foundation processor and the S-1500 amplifier. Mark Henninger, from the AVS Forum Press was very impressed by what he heard. Here are a few of the highlights. 
"What I heard was quite stunning-a rear soundstage that had the same depth and definition I am used to hearing from the front. I know that is the multichannel ideal, but up until that point it had not occurred to me that the soundfield could truly be seamless and three-dimensional around the full circumference of the system."    
"More than anything else, the new Foundation amazed me with its fidelity, which has always been Krell's mission-to deliver the ultimate in sound quality."   
"Krell's Foundation brings the listener closer to that ideal than any 7.1 AV processor I have heard to date." 

Apart from support for the expected audio CODECS, the Foundation sports a plethora of HDMI ports, provides RS-232 and Ethernet connectivity, and make provisions for Krell’s proprietary ARES room EQ system.

It offers fully balanced output stages, as you can see from all those XLR outs. Ever conscious that the surround audiophile may also be a stereo audiophile, it supplements its eight HDMI ins and two outs with a stereo preamp mode that keeps the signal entirely in the analog domain. Add some combination of Krell's five-, three-, or two-channel power amps and you've got a compelling system.

Orange, CT and Las Vegas, NV (CES) - January 9, 2013 - Krell Industries, LLC, the leader in high performance music and home theater systems, announces Foundation, the latest in a long line of state-of-the-art A/V processors. Featuring the latest digital connectivity, the Foundation also maintains Krell's exacting standards for analog audio reproduction.
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.
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 beneficial for those with televisions with built-in web streaming capability like Netflix 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 flexibility and ease-of-use in mind, with extensive routing capability of the audio inputs to the various outputs. During setup, the specific 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.
