Interfacing Unity Intercom to Analog Intercom using Dante

We often get calls from customers looking to connect their existing analog intercom systems to the intercom solutions provided by Unity Intercom. This can be easily done by installing DanteĀ® Virtual Soundcard on the Mac running Unity Server. Then Dante Controller can be used to route any Dante audio to/from the Unity system.

Studio Technologies’ Model 44D Audio Interface is intended to be used to connect two channels of analog 4-wire intercom to a Dante network.

(https://www.nti-audio.com/en/products/minirator-mr-pro-mr2). While it was designed as a general-purpose audio generator with some test capabilities it ends up being fantastic for analog PL intercom work. It will directly measure impedance and DC voltage, independently from pin 2 to pin 1 and from pin 3 to pin 1, exactly what you need to understand a PL circuit’s characteristics.
