Does my bluetooth speaker transmit a wireless signal to my other bluetooth speaker?

The following units can pair with other like units via Bluetooth.
BRS-130
GSP-L2200PK
GD-L115BT
If you are trying to pair 2 powered PA speakers connect an XLR cable from the MIX OUT jack of the source speaker into the line in XLR jack on the receiving unit.
