eARC question.

[Schizophonic]

I'm looking to take the plunge in purchasing a new amp and one of the main pet hates I have with my current setup is that I have to switch on the TV (LG 55BX) and my current AMP to get sound running. Switching off the TV it switches off the amp too.

I'm using Optical out of the TV and into my current AMP. I assume with the new AMP I'm getting Denon X2700H I can just use one HDMI cable and when I switch on and off the TV, the amp it comes on and off by listening to the signal off the TV?

So what you’re referring to is a feature independent of ARC (audio return channel)

You’re talking about CEC (consumer electronics control)


This is a setting you’d need to enable on the TV and AVR


Some amps have IR control too

Thanks, looking on the net it seems it refers to HDMI CEC.

I have an Denon 1910 Amp if anyone have any experience with this device. I always for HDMI eARC the device to switch on and off.

CEC is, as far as I’m aware, unique to HDMI so unless you use it with your Denon amp, you may not be able to use it.

That being said, it may have other, legacy, features, such as IR control. Worth having a look through the manual for it

Do you remember those Venn diagrams from maths class? Sometimes two or more circles would partially overlap, and other times one circle would be entirely inside another. Well, eARC and ARC and HDMI CEC would be one of those times when you've got a circle inside another circle inside another circle.

eARC is a sub feature of ARC, and ARC is a sub feature of HDMI CEC. In other words, you can't have eARC without ARC, and you can't have ARC without HDMI CEC.

HDMI CEC will take care of switching the amp on and selecting the correct input. It will also allow you then to use the TV remote volume controls to operate the AV receiver volume control. ARC takes care of getting sound from the TV down the HDMI cable to the amp. eARC refines that process by adding support for a wider range of sound formats.

That's about all there is to it. It'll need a little setting up. HDMI CEC should be enabled on both the TV and the amp. ARC/eARC will need to be selected on the amp, and the TV will need a selection made in the audio setup menus to direct sound to "Home Cinema" (or words to that effect) instead of TV Speakers. After that though you're good to go and the next time the system is used it'll just do what you've set up.

Thanks for the explanation, to your knowledge does this involve turning on the AMP on and off automatically when the TV comes on and off?

Yes, as long as the amp support HDMI CEC which the Denons do, and so long as it's in standby which it should be,then yes, the amp will switch on and off with the source.

Thank you, i'll look into the model that Im thinking to purchase.
