09.18.2007 — PRESS RELEASE

Mount Vernon, NY, July 25th, 2007 – Key Digital Systems, Inc., the leader in video technology and solutions, is introducing two all new HDMI switchers/distribution amplifiers in the KD-HDMI2x4P and KD-HDMI2x8P. These two new switchers can accommodate up to two HDMI inputs and distribute these signals into four (KD-HDMI2x4P) or eight (KD-HDMI2x8P) video outputs. Both switchers are HDMI 1.3 compliant with the capacity to handle all video signals from standard definition 480i to full HD 1080p.

Features for these switchers include:

- Supports coaxial digital audio, optical digital audio (Toslink) and analog audio
- Key Digital IAS circuit automatically senses and switches to the active video input
- Flexible EDID control manages the HDMI communication for any output
- Fully controllable through RS-232.
- Supports any HDMI resolution at 50Hz or 60 Hz.
- Can be cascaded to support up to 100 HDMI video displays

Michael Lakhter, VP, Sales for Key Digital says, “Our two new HDMI switchers set a new industry standard for flexibility and capability. We have a unique design in incorporating two-way EDID communication for HDMI devices. This “first to market” technology assures the customer that all products wired through the KD-HDMI2x4P and KD-HDMI2x8P will have perfect high definition images and that will not be down converted due to poor communication between source and display.”

The KD-HDMI2x4P and KD-HDMI2x8P have MSRP pricing of $825, and $2000, respectively.
