jfh Posted January 23, 2023 Share Posted January 23, 2023 Should I avoid using eARC between a Control4 connected TV (Samsung Frame 2022) and Marantz AVR? it was recommended years ago to me to use separate TOSlink or digital coax connections instead but I don’t know if that is still the recommendation Quote Link to comment Share on other sites More sharing options...

AP-123 Posted January 23, 2023 Share Posted January 23, 2023 Yes. Still avoid it My media closet is far from my tv and inaccessible. I use it. Would you mind sharing why to avoid it?Sent from my iPhone using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
msgreenf Posted January 23, 2023 Share Posted January 23, 2023 Earc requires CEC. CEC and c4 don't play well together as you have 2 competing control planes Quote Link to comment Share on other sites More sharing options...
Cyknight Posted January 23, 2023 Share Posted January 23, 2023 As per above, consider every possible other option before going to eARC. C4 and CEC are not by default mutually exclusive - indeed there are HDMI switches that provide CEC control TO C4 setups - but there are so many potential pitfalls combining the two in general that it's best avoided.

jfh Posted January 23, 2023 Author Share Posted January 23, 2023 Is toslink/optical or digital coax better? Quote Link to comment Share on other sites More sharing options...
zaphod Posted January 23, 2023 Share Posted January 23, 2023 Better for what? They both send the same 1s and 0s. Which one you prefer may depend on your equipment - for example, C4 controllers have coax outputs, but not toslink. Older C4 matrix amps would take coax but not toslink as well.

Cyknight Posted January 23, 2023 Share Posted January 23, 2023 The only advantage of optical is that it can't pick up interference, but the signal quality as such is identical Quote Link to comment Share on other sites More sharing options...
jfh Posted January 23, 2023 Author Share Posted January 23, 2023 Mostly concerned if they will both handle the newer audio formats. Had read some articles (old) that indicated they couldn’t handle the new Dolby stuff which didn’t make sense to me but I know nothing about audio Quote Link to comment Share on other sites More sharing options...
RAV Posted January 23, 2023 Share Posted January 23, 2023 Typically, it's recommended to use a streamer box (AppleTV, Roku, Nvidia Shield) rather than the built in apps of the TV. That eliminates needing an Audio Return from the TV. You're correct in Optical or Digital Coax does not handle all the surround formats that eARC can. But any of the mentioned streamer boxes will bass all surround formats through the HDMI to the receiver to process, and then the receiver passes the video on to the TV. All Video Sources -> Receiver -> Single HDMI input on OneConnectBox -> Frame TV Quote Link to comment Share on other sites More sharing options...
jfh Posted January 23, 2023 Author Share Posted January 23, 2023 Yes, I realize that and probably won’t use any of the TV apps. The vast usage source would be HDMI via video matrix or a local,Roku. Just trying to understand options. Quote Link to comment Share on other sites More sharing options...
Cyknight Posted January 23, 2023 Share Posted January 23, 2023 Yes if you have a full atmos setup, save yourself the trouble and get a roku.... Note that if you 'just' have a normal 5.1 or 7.1 setup, you're not losing anything by not getting atmos. Quote Link to comment Share on other sites More sharing options...
jfh Posted January 23, 2023 Author Share Posted January 23, 2023 Thanks. This TV will probably remain 5.1 so good to know I don’t really need to care. Quote Link to comment Share on other sites More sharing options...
