There are also brick-style housing versions that can be used on any surface or rackmounted using the accessory rack kits if preferred. TPRO receivers with skew compensation adjustments are optional and help adjust for misconvergence of the red, green, and blue video signals that can occur as a result of inherent delay caused by differences in cable twist lengths. The system can be powered at either the transmitter or receiver end by the optional power supply.
The Gefen ToolBox 8x8 Matrix for HDMI with FST (Fast Switching Technology) allows direct connections between different high definition sources and displays without networking. Any eight sources can be switched to any eight displays using this new matrix. High-definition resolutions up to 1080p full HD with 3DTV passthrough are delivered instantly when selected. FST is a Gefen technology that speeds the HDCP (high-bandwidth digital content protection) handshaking process, which in the past could take up to 10 seconds in transition when switching between sources. With FST, those 10 seconds have been reduced to nearly no delay when switching sources, with high-definition video appearing on the display immediately with no latency. Installation is simple, requiring the connection of eight high-def sources to the eight HDMI inputs, and the connection of eight high-def displays to the eight HDMI outputs. Users can assign any source to any display, relaying video and multi-channel digital audio with no signal delays. The 8x8 Matrix for HDMI with FST offers local front-panel control, IR remote access and RS-232 for automation, IP control, and is a lower cost alternative to previous product offerings.
