Low or No Atmos Height Effect From Arc

24 replies

Hi guys,

I am getting very little or no Atmos height effects from my Arc.

The Arc is 6.5 feet from my ceiling and I'm seated at about 6+ feet away from the Arc. I have done Truplay as well. I don't even feel Atmos in the front stage as well. The Arc is seated on the TV console about 2 feet off the floor. There is nothing blocking the Arc speakers.

I have tried raising the Arc from it's rear and front about an inch but I don't hear any improvement. The dealer told me to get the Arc checked out at the service centre but I doubt it's faulty. I am able to hear the pink noise from the Atmos 5.1.2 test clip but the audio is distinctly coming from the front. It does not seem to be bouncing off the ceiling.

Besides that the Arc is a solid upgrade from my Klipsch Cinema 600. Any advise or help would be greatly appreciated.

Cheers,

Kelvin from Singapore

Hi all.

I think I have resolved the issue. Make sure to set your TV's digital audio output to passthrough and not auto. I can now hear Atmos height effects.

Auto let's the TV process the audio signal. Passthrough will send an unfiltered audio signal to the Arc.

Hope this helps those who are facing the same issue.

Have you adjusted the height audio level of the Arc in the Sonos app?

Yes I did I set it at +5 or +7 even.

I just measured my distance from the Arc. I'm 8 feet away.

What specific Dolby Atmos content are you testing? Just because you are watching something in Dolby Atmos doesn’t mean you’ll hear height effects all of the time. The height channels are actually used very seldom with most Atmos content.

Try to sit 5-7 feet away from the Arc and set the height audio level to +8.

I'll try to see if I can move my couch.

Any advise on Truplay? Should I cover the bubble of the MLP or the whole room?

It is recommended to cover the entire room. But you could try both ways and see which one produces the best results to your ears.

I have increased the height channel level and done truplay twice. The height effects seem to be coming from the front rather then above.

I watched a video by Peter Pee, he advised to raise the back of the Arc based on the seating distance. Does this make sense as it will block the front speakers...

You could raise the back of the Arc a little. This would change the angle of the upward firing drivers to reach a further distance from the Arc. But this shouldn’t be necessary if you are already seated 5-7 feet from the Arc.

What specific Dolby Atmos content have you tested? You need to find content with clear height channel effects.

If you have a premium Netflix subscription, try testing the film Roma at around the 1:03:25 mark. For a few minutes you should clearly hear the trees burning/crackling above you.

I tried the wandering earth with electricity sparks. Seems to be coming from the front sound stage.

Will try Roma.

Do you think the Arc is faulty? I don't think this is a fault though...
