4K HDR HDBaseT™ Extender Set with 2-Way PoH, IR and RS-232 (4K: 35m/115ft | 1080p: 70m/230ft)


For extension of 4K UltraHD and HDR transmissions over medium distances in residential or commercial applications, the EX-35-H2 features the Class B HDBaseT™ platform with full HDR support to distribute 4K UHD HDR, audio, bidirectional IR/RS-232 and two-way PoH to remotely power either transmitter or receiver up to 35m/115ft or 1080p up to 70m/230ft.




No 2 installs are the same; that’s why we’ve enabled all of the H2 extender line up to be powered from either the TX or RX, meaning maximum flexibility on-site without hunting for a mains outlet.


Transmission of HDR-10 content is nothing new to WyreStorm; we’ve been sending this high-bandwidth content, native & uncompressed over long distances since the introduction of our first H2 extender in 2015. The EX-35-H2 is no different, sending pixel-perfect 4K UHD 4:2:0 10-bit @24Hz at distances up to 70m/230ft.

Signal Re-clocking

Installers shouldn’t experience problems because of source equipment they have no control over. That’s why all extenders in the WyreStorm H2 family automatically “re-clock” the source signal, overcoming clock-stretching issues found in certain source devices.


The latest 4K UHD content arriving via satellite, cable, disc or stream is all heavily encrypted. Being part of the H2 product family, the EX-70-H2X supports the multi-point distribution of this content over HDBaseT™.
