Atmos amp

[jimmybond007]

Can anyone help please? I’m wondering whether an Atmos amp will decode any Atmos content if the TV was connected directly to or does the TV (or other streaming device i connect to the amp) play a part?

If you feed your amp something other than Atmos, you won't get Atmos.

The only way to get Atmos out of a TV would be if the TV supports eARC HDMI connectivity. If it just supports ARC or only has a Toslink audio connection to the AV receiver, then that will degrade audio. As well. not all TVs pass on the highest quality audio through their audio outputs.

If you have a source that accepts and passes on Atmos audio, then the receiver will process that Atmos audio and should do so without issue.

If you have a more specific set of questions with actual equipment, then that can help.

Be aware, just because a streaming device, like a Roku Ultra, can pass Atmos audio through it, that doesn't mean that every stream will include Atmos audio as an option. Only certain programs contain Atmos audio.

The audio feed should be going to the receiver, then to the TV, not the other way around. The TV should be the final part of the chain, not the beginning. The receiver will always do a better job at signal detection and decoding.

You'd need an eARC capable tv/avr (audio video receiver, more comprehensive a term than "amp"....to me an amp is only a power amp) to get lossless audio from a tv-derived source, and fairly new gear might accommodate such. If you have an older tv or avr then easier to run sources thru the avr, and even if your tv had some sort of lossless audio capabilities, no way to get it to an avr. I'd not use a tv as a switching center or a source myself, just as a display. Posting up what specific gear you've got or are thinking about would be more helpful....

Smart TVs supporting ARC can pass lossy Dolby Digital Plus 7.1 based Atmos to receivers. Optical can also pass Atmos these days from certain streaming services using certain Smart TV apps. To pass lossless Dolby TrueHD based Atmos from an external device connected directly to the TV, eARC is necessary. Sometimes, mostly with new gaming consoles and some streamers, it is necessary to connect a device directly to the TV to get the most out of the device concerning video output and one has to use ARC/eARC for audio. Some have only a Smart TV for streaming content and the TV is both a display and streaming device in one. As always, the model numbers of all of the equipment in play would be most helpful.

The Firestick 4K Max and the AppleTV 4K each support Atmos with Netflix and Prime and Disney+ and HBOMax etc. Beware not every streamer supports Atmos on all apps. Do the research.

The Firestick 4K Max or AppleTV 4K can just connect HDMI to the Atmos capable Receiver. Then run another 4K HDMI cable from receiver to the 4K TV. You can use the receivers Dolby Upmixer on any content that’s not already Atmos. The results of the upmixer will vary compared to real Atmos content but it does pretty good.
