What's the difference between Upstream and Downstream Devices?
Hello Everyone. I was recently watching some training videos from Extron and Q-Sys saw them mentioning upstream and downstream devices. But these were never defined in these courses neither I could find anything regarding Upstream and Downstream in CTS Exam guide. Not much info is available on internet either regarding AV upstream and Downstreams
I would really appreciate if someone could explain what are upstream and downstream devices/signals.
