This Samsung SWA-5000 wireless receiver/amplifier is designed specifically to allow "wireless" surround channel speaker connection from the Samsung HT-D5500 or HT-E550W 5.1 channel home theater receiver/Blu-ray player system. Samsung information states that it will be compatible with some other home theater receivers of 2010 or later design. I have seen no information that suggests it will be compatible with Samsung soundbars or earlier receivers

This wireless adapter is designed to eliminate requirement of running wires from your HT- receiver/player main control unit along side walls, which might otherwise require crossing doorways and other obstacles. The rear channel sound is instead transmitted wirelessly to this receiver/adapter, which also includes two speaker amplifier channels. Speaker wires from this one unit, which may be unobtrusively placed or hidden, do run from the adapter, usually along baseboard of rear wall, to the surround speakers. You may use Samsung or other surround speakers. These wires are included with this SWA-5000.

Required to operate, and NOT included with this wireless adapter/amplifier module is the "TX" transmitter card that plugs into a slot on the back of the HT-D5500 or other Samsung receiver/main unit. So, this unit is most likely to be needed and purchased if you already own a Samsung home theater receiver, known to be compatible with rear channel transmitter card, and your SWA-5000 unit has failed or was not with your receiver when you acquired it. If you have a Samsung system of manufacture earlier than 2010, you may assume this adapter is not compatible, and if your Samsung receiver is equipped with the TX card, but is other model than HT-D5500, you should confirm with Samsung the compatibility of this SWA-5000 wireless receiver/amplifier adapter with your HT- model.
