Key Digital Provides an Audio Management Solution via our Digital IQ Series HDMI Matrix Switchers

Posted on Monday, April 30, 2012

Mount Vernon, NY. Key Digital Systems, Inc. – April 23, 2012 – Key Digital is proud to announce a solution to the problem of managing audio via an HDMI Matrix switcher. 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™ model KD-CATHD500 HDBaseT HDMI balun kit. KD-HD8X8BT in three zones with different characteristics:

KD-HD8X8BT

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 zone.

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.

The official press launch for Key Digital’s first ever control system - Compass Control
can satisfy all of these zoning requirements with the help of the EDID control feature. ® - will be held at Key Digital’s Mount Vernon, NY headquarters on May 7th, 2012 – for more information click here.
