Hi @lJoel, welcome to the Sonos community. Thank you for reaching out to us and letting us know about your concern. May I ask, what is the make and model of your projector? If you’re planning to purchase a Connect Amp you may need to get a splitter to connect it to your projector. Before you proceed to purchase any products, it would be best to know your devices and how they will work with Sonos. You have great support here in the community. Our community members can share their suggestions and feedback on what’s best for you. You may also contact our sales specialists through phone or email where you can send the floor plan for further assistance. If you have any questions about this. We and the community are always here to help.

You cannot “BT sync” any Sonos speaker.
