Know before you buy
Yes, the HA5-12G is designed to bridge HDMI 2.0 sources to 12G-SDI, which allows for significantly longer cable runs compared to standard HDMI. For extremely long distances, AJA also offers specific fiber SFP models that can extend your signal even further.
It does. You can embed up to 8 channels of audio directly from the HDMI source, or use the 2-channel analog RCA inputs if you need to bring in external audio.
Not at all. The device is configured via a simple USB connection to your computer, making it straightforward to manage settings without complex menus or hardware switches.
The HA5-12G features zero-millisecond latency, ensuring your video signal remains perfectly synced for live production environments.
The unit accepts a wide range of power from 5 to 20 VDC and includes a universal power supply in the box, so it is ready to use in most regions without additional adapters.
The dual outputs allow you to send the same converted signal to two different SDI destinations simultaneously, such as a monitor and a recording deck, without needing an additional distribution amplifier.
