Thanks!
You outline your system but not the issue you are experiencing.
Sorry if that wasn't clear: the second floor TVs aren't part of the first floor C4 system. They are standalone TVs.
is there a reason the system was designed with 6 tvs but a 4x4 matrix? the sources in the 4x4 switch, are they not to be shared with second floor tvs - they have their own sources connected locally?
I am not sure why they designed it this way, or why they designed the EA5 to be located on the first floor instead of in the basement. I assume they did it because it was easier/cheaper to run HDMI/IR because 2 of the 3 TVs on the first floor share a common wall with the media cabinet, and the third TV is only about 25 feet away in the next room. That's not how I would have designed this network, but, yes, the way it is set up now, the 4x4 matrix is enough because the first floor only has 3 TVs and each second floor TV is separate with its own source(s) and not connected at all to the C4 setup on the first floor.
how many cat6 drops at each tv?
Just 1. Unfortunately, there is no conduit to easily pull more, so running additional drops is going to be major engineering. Assume that isn't an option.
what model TVs? If they are TVs running Android you could put an IRUSB at each TV in the USB input and use that IR to control the soundbar if the soundbar has an IR receiver (not sure how those sound bars work).
Samsung, but I don't want to depend on having a particular model of TV. The Sonos units are connected via digital audio to the TVs and integrated into the Sonos network, so that part of the setup is fine. I am basically trying to eliminate the local sources at each of the second floor TVs and get them integrated into the C4 network.
You could also sell the 4x4 and buy a bigger HDMI HDBaseT matrix or get a flexible/scalable Video over IP distribution system and that will give you extra IR at each location too.
Yes, those are the two ideas I mentioned above. With HDBaseT, though, I can't get to the first floor media cabinet since I don't have any direct runs to that cabinet from the second floor. That's why my first idea was HDBaseT in the basement because I have direct runs from the TVs' drops to the basement, so HDBaseT would work. I would need an appropriate EA director for that option. Would an EA1 work for that? To get to the first floor media cabinet, I would have to go with an IP-based video distribution solution. That would certainly be more flexible. All 6 of the TVs could share all of the same sources.
I am looking for ideas on equipment (particularly video distribution over IP) that people have used successfully in situations like this and whether adding an EA1 would work if HDBaseT is the better/only route.
If you just need extra cable behind each TV you can put a small splitter to get an extra cable.
Nope. Just trying to get the second floor to join the first floor's C4 party.
