As we know, a party line 2wire circuit requires a termination load.  This solution provides a schematic of that circuit with an XLR connector to plug into the line to add the termination.  But the user should be sure to only add this if there is no termination on that circuit, otherwise there will be a double termination and that will make it impossible to null and drag down the volume of the channel.

In the real world if you don’t have a proper Clear-Com power supply… just a 30vDC PSU and want to use it for comms.  The BA-1 would supply the termination circuit for the system.
