Wireless-ready

There's a wireless transmitter on the back of the SC-BT200, but you need to buy a separate wireless transceiver to enable wireless functionality. The SH-FX70 wireless transceiver can be purchased separately for $130, but note that it only powers a pair of speakers; if you want both your surround and surround back speakers to be wireless, you'll need to purchase two SH-FX70 units.
