No, the Beam can not be connected to your receiver, unless your receiver has an optical output. It will not work off of an HDMI output, it's looking for the ARC (Audio Return Channel) of an HDMI-ARC, which I've never seen on a receiver...only on TVs.
Note, the Beam isn't a center speaker. It's the left, center, and right speaker.
