Model Number: AT-HDCAT-8

The Atlona AT-HDCAT-8 is an HDMI to HDBaseTTM distribution amplifier with two HDMI inputs and eight, long distance HDBaseT outputs.  It features auto-switching with manual override between the two HDMI inputs and an HDMI output for routing to an AVR or cascading up to eight units.  Each long distance output transmits AV signals up 230ft (70 m).  The distribution amplifier is redundant-power supply-ready and provides PoCc (Power over Category cable) for compatible Atlona receivers plus audio de-embedding to S/PDIF and balanced captive screw outputs for AVRs and sound reinforcement systems.  The AT-HDCAT-8 is ideal for digital signage applications, entertainment venues, and residential applications where one or two AV signals must be distributed to multiple, extended distance displays. 

NOTE: The AT-HDCAT-8 is discontinued. A new version of this product is available as the AT-UHD-CAT-8.
