Product Description

Atlona AT-UHD-EX-100CEA-KIT 4K / UHD HDBaseT TX/RX w/Ethernet Control PoE and Return Optical Audio ATNO-UHD100CEAK

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

4K/UHD HDMI Over 100M HDBaseT TX/RX with Ethernet, Control and PoE and Return Optical Audio

The Atlona AT-UHD-EX-100CEA-KIT is an HDBaseT transmitter/receiver kit for HDMI transmission up to 328 feet (100 meters) over category cable with Ethernet pass through, RS-232 and IR control, Power over Ethernet, and optical audio from receiver to transmitter. This extender kit transmits video signals up to 4K/UHD @ 60Hz, 8-bit color, 4:2:0 chroma subsampling with embedded multi-channel audio and remote 48V power for the receiver. A digital audio pathway returning back across the HDBaseT link from a smart TV to an AVR routes multi-channel audio using TOSLINK optical connectors. Additionally, the kit extends Ethernet, RS-232, and 12 volt-based IR control commands. The kit is HDCP 2.2 compliant and supports EDID communication. Both transmitter and receiver feature one-third rack width metal enclosures for easy rack mounting with rear panel I/O ports for uncluttered wire management.
