Teranex AV simultaneous conversion

Hello, I’m not sure if I fully understand this product. Does the Teranex AV allow input of an SDI signal ‘A’ in 4K60 and output ‘A’ at 1080p60, and do the same with a different signal at input ‘B’, outputting at 1080p through output ‘B’, and similarly with a third input ‘C’ via HDMI, converting it to 1080p60 on the HDMI output?

I would use it to separate the 4K content generated by the ATEM Television Studio 4K for recording, from the ATEM Production 4K (set to 1080) for streaming (which lacks an internal scaler).

Could it handle all three conversions simultaneously?

And how could I use the 3G SDI outputs CH 1, 2, 3, and 4 if they’re not for a TV wall?

There is only one conversion. The different connection ports allow you to input or output different types of signal. IE) the 4 channels would support a 4k quad link

And how could I use the 3G SDI outputs CH 1, 2, 3, and 4 if they’re not for a TV wall?

I believe the four 3G-SDI outputs cane be used in Quad-3G mode for 2160p50/59.94/60 output support - as Quad-3G is often used instead of 12G-SDI in production.
