The Premium Extender for Residential Systems The AT-UHD-EX-100CEA-KIT is a premium HDBaseT extender pair for residential systems that require audio from the TV to be amplified by an AVR near the set top box located at some distance from the TV. Return audio may be any audio signal including Dolby or DTS up to 5.1 (based on limitations of optical audio standard). The kit utilizes HDBaseT technology specifically designed to support audio extension based on HDBaseT 2.0 compared with some other solutions which use HDBaseT control channels to transmit return audio which may cause latency or quality issues. The AT-UHD-EX-100CEA-KIT is ideal for use in residential installations with AVRs and STBs located in a separate area from the TV at longer distances than HDMI cables can support. The receiver to transmitter audio pathway supports digital audio from: -Off-air tuners in many TVs -Game systems located in the same room as TV -Smart TVs with internal apps such as Amazon Prime Video, Hulu and Netflix
