I’ve just ordered an AWOL Aetherion max projector, and I’m planning on an Arc ultra and Era 300 set up. I’ve just got off the phone with Sonos and they told me that their products are designed for use with TV’s not projectors and that there could be a syncing issue if I try and connect this set up to a UST projector. The projector does have an HDMI eArc connector. Before I spend a lot of money can anyone advise me if there may be some truth in what Sonos are saying or would I expect no problems at all? Thanks

The main problem of using Sonos with projectors is the distance between the projector and the soundbar.  The eARC connection is via HDMI, and HDMI signals deteriorate over distance when using standard HDMI cables.  That’s not even taking into account any wiring factors.  However, if you can wire an HDMI cable from the eARC port on the projector to the Arc Ultra, and are prepared to pay a premium for active HDMI cables, either fiber optic or signal booster types for distances over 15-20 or so feet, then it will work.

Thanks for your reply. I’ll be using a UST projector, so the Arc ultra will be no more than a couple of feet away from the projector. I’ll use the eArc connection too.
