Hi Matthew, Tria+UHD is limited to two UHD channels.
In UHD, It can ingest XAVC-I at either Class 300 or Class 480.
It can also ingest 1080p, At XAVC-I class 100, also limited to two channels.
Unfortunately there is no option to upgrade the channel count.
There are other Ross products, like new Media I/O models that can support up to 4 UHD channels, and also support other codecs such as ProRes and DNxHD/HR.
