ARC Ref3 Bal-SE button..what for?


I was wondering what the BAL/SE button on the ARC Ref is for? I have my cdp connected to the balanced inputs but when I push the BAL/SE button on the Ref 3, I still hear music. Can someone please explain what this button is supposed to do?

Maybe that's why I thought the Ref 3 sounded thin in my system.... I had a dealer loan without a manual...

Thanks for the corrections!
