What you are actually doing here is interfacing a two-wire intercom (the RTS) to a four-wire system (the Blackmagic). The difference is this: a two-wire system has bi-directional audio, like a phone line; in a four-wire system one pair sends audio out while the second pair receives incoming audio.

The "textbook" solution, if you are using an RTS system, would be to use their SSA-324 system interface. The connection would be like this:

1) Plug the RTS party line XLR feed into the SSA's 2-wire I/O jack;

2) Connect the headphone out from the Blackmagic interface to the SSA's 4-wire in;

3) Connect the SSA's 4-wire out through an attenuator pad to the Blackmagic interface's mic in (the attenuator drops the SSA's line level down to mic level).

The SSA has two sections (A and B), so you can use this to separately tie to two Blackmagic converters.
