My receiver, Atmos & Amazon Fire stick


Well-known Member
Hi all,

Apologies if this isn’t posted in the correct place.

I have an Anthem 720 with a 5.1 setup.

I’m using an Amazon fire stick to stream stuff.

As I’m not using a back channel, I have that option turned off. However, I only ever have Dolby+ showing up.

If I turn on the back channel option (even though there isn’t actually a physical speaker), suddenly it’ll switch to Atmos.

My question is: by turning off the back channel, am I reverting to lossy sound or is it in fact lossless? It’s really difficult to understand the best settings!

With thanks,
