AJA Hi5-12G and HA5-12G Mini-Converters Speed Long Distance Transmission

AJA hi5 ha5 12g

AJA's new 12G Mini-Converters, the Hi5-12G and HA5-12G speed up and simplify the transmission of high resolution, high frame rate and deep colour content over long distances. Each of them is available in three model configurations, with or without Fibre SFPs.


The next development of Hi5-4K-Plus, Hi5-12G converts a 4K/UltraHD/2K/HD 12G-SDI single-link input with eight channels of embedded digital audio to an HDMI 2.0 output with two or eight channels of audio. Hi5-12G can also generate HDR metadata in accordance with HDMI v2.0b/CTA-861-G. [HDMI v2.0b is the specification defining your connection, and CTA-861-G is a DTV profile for uncompressed high speed digital interfaces.]

The device has a 12G-SDI single-link input with a re-clocked SDI loop out for simpler confidence monitoring or pass on for SDI pipelines. Fibre SFP-equipped Hi5-12G models include the Hi5-12G-R receiver, which extends HDMI 4K signals over long distances from either an SDI or a Fibre connected source, and the Hi5-12G-TR transceiver, which delivers a 4K/UltraHD SDI or Fibre source signal to an HDMI destination. It is capable of passing on the source signal through SDI or Fibre to a secondary destination. Hi5-12G models include a DWP-U power supply, like all AJA mini-converters, and USB port for firmware updates.


HA5-12G, the next version of AJA’s HA5-4K Mini-Converter, allows users to convert an HDMI 2.0 input with up to eight channels of audio from the HDMI source or two-channel analogue audio (RCA) to two 12G-SDI single-link outputs with eight or two channels of digital embedded audio. HA5-12G is also capable of analysing HDR infoframe data coming in over HDMI in accordance with HDMI v2.0b/CTA-861-G.   

The portable converter includes two SDI DA outputs and transmits 12G-SDI on each SDI link, reducing cable runs when transporting 4K/UltraHD SDI. Fibre SFP-equipped HA5-12G models include the HA5-12G-T single-channel transmitter, which extends HDMI 4K signals over long distances (10km Single-Mode), and the HA5-12G-2T dual-channel transmitter. The two 12G-SDI coaxial outputs and two 12G-SDI over Fibre outputs simultaneously enable HDMI 4K source extension to multiple locations without a distribution amplifier. HA5-12G models include a DWP-U power supply and USB port for firmware updates.

All versions of these new Hi5-12G and HA5-12G mini-converters will be available in mid-2018. https://www.aja.com/
