Single unit only (not a pair). I do not know if/how it can be connected to your system. Only buy if you know how.
Appears to be in very good condition. Powers on, not tested further. Assumed to be fully working. If not I'll pay for return postage and give a refund. I do not know if it works. Minor marks.
Includes only what is shown in photos. No other accessories. No original packaging.
