Hi, and thank you for your question. Unfortunately we cannot integrate Arc with your stereo system but worth noting that Arc has discrete surround sounds built into it. Arc would plug directly into the back of your tv with HDMI ARC, eARC, or Optical via the included optical adapter.

Hi, and thank you for your question. Yes you can! When you set up beam, we will automatically walk you through the remote set up with any IR remote. If your Beam is already set up, you can do this now by going to settings -> system -> select room name -> scroll down under TV setup you'll see "Remote Control Setup". We'll ask you to press volume +,-, and mute 3x's and that's it! :) - As always we're here to help you set that up if needed. Feel free to head over to sonos.com/support and reach out to us whichever way you prefer.

Hi, and thank you for your question. We would not recommend putting it in a closed cabinet for 2 reason. The first is heat dissipation. Although we use incredibly efficient amplifiers heat is still lost and needs a place to go. The other is wifi signal. Having a completely closed cabinet could interrupt wifi connection potentially depending on the material of the cabinet.

Thank you for your question. Yes, you can have up to 32 of our products on one system all playing the same thing or different sound in different rooms. We have over 150 streaming services you can use with our system and Pandora is absolutely one of them! If you want to use Sonos One as surround sounds you'll need two of them. Also, you'll need to separate them as surrounds every time you want to use them in other rooms for music. If you don't, they will be part of the Beam as a home theater system. This is very easy to do in the app.
