TSA6175 is a Bluetooth 5 multipoint audio receiver. You can have many TSA6175s paired and work together. You can also let it work like a normal Bluetooth audio receiver.

This Bluetooth music receiver connects to the line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system.  

If you have audio systems in different rooms, you can use multiple TSA6175 audio receiver boards and connect all of them together. When your smartphone connects to the master module and plays music, all audio systems will have audio output.

One board works like a normal receiver

Multiple boards work together
