Key Digital Provides an Audio Management Solution Via Our Digital IQ Series HDMI Matrix Switchers

MOUNT VERNON, N.Y., May 9, 2012

Key Digital is proud to announce a solution to the problem of managing audio
via an HDMI Matrix switcher.

With the proliferation of a wide variety of audio formats and the increased
demand to be able to utilize all of these various formats, it is becoming
increasingly difficult to both manage all of these formats and preserve the
best audio quality for the end user. Digital IQ series HDMI matrix switchers
such as Key Digital's brand new KD-HD8X8BT are uniquely capable in this
capacity. Key Digital's Digital IQ series model KD-HD8X8BT HDMI matrix
switcher supports HDBaseT and can be used with the FatCat Series(TM) model
KD-CATHD500 HDBaseT HDMI balun kit.

Let us assume you use KD-HD8X8BT in three zones with different

1. Zone with a flat screen TV with built-in stereo speakers. For this zone
you will need HDMI with a stereo audio signal.2. Home theater zone with the
latest 7.1 channel AV receiver, speakers, and flat screen TV3.
Home theater zone with an older non-HDMI 5.1 AV receiver capable of Dolby
Digital with flat screen TV

KD-HD8X8BT can satisfy all of these zoning requirements with the help of the
EDID control feature.

For Zone 1, the installer would make sure that L/R stereo audio is available
from every source. On output 1 you would program that output to insert PCM
stereo into the HDMI signal instead of any other audio format. The PCM
stereo is created and outputted in place of L/R stereo inside the switcher.

For Zone 2, you would pass the HDMI signal (containing authentic audio) with
its highest [quality] available audio format. For sources sending DTS-HD,
DTS-HD would be the preferred audio format for this zone. The flat screen TV
can be connected to the HDMI output for the AV receiver associated with this

For Zone 3, the HDMI output is programmed to insert Dolby Digital 5.1
surround sound. The PCM coaxial output will provide Dolby Digital to the AV
receiver. This zone will only have audio available from the AV receiver and
speakers, the flat screen TV will ignore the Dolby Digital audio and display
only video.

Key Digital(R) will be displaying Compass Control(R) at InfoComm 2012
