Yes, the tactical fiber brand box *IS* exactly a ClearCom interface with an included VERY expensive adapter cable.
For reference, the EF-1M was replaced by the EF-701M but both units serve the same purpose, to interface a powered bi-directional ClearCom channel to a non-powered separate talk and listen circuit. This is exactly what the Studio Converter needs, well almost-read on.
You will have to get or make your own interface cable and connect the 4W in and out from the EF1M to the mic/headphone connections on the Studio Converter. The studio converter uses AES digital audio instead of the analog audio from the EF1M. You will need an additional converter like the Flying Cow or something to convert the Clearcom analog audio to BMD AES digital audio and vice versa.
The analog audio talk and listen from the EF-1M are available on both the RJ45 and DB-15 connectors on the rear of the unit, use either but not both. Connect the "Audio to party line" to the input of your AES converter, and the AES out to the BNC labeled Mic In on the SC2. The Headphone Out BNC from the SC2 should feed into a reverse AES converter, and the analog output connects to the "Audio from Party Line" on the EF-1M. Lastly, the XLR from the EF-1M connects to your existing ClearCom channel. If all goes well the ClearCom PL will now communicate with the camera converters connected to your SC2.
There are some adjustments required on the EF-1M to achieve optimal intercom performance/quality. Follow the user guide steps for nulling after you get it talking. I'd suggest setting the Send and Receive levels midway to start. Even with the interface adjusted perfectly, I was never happy with the way BMD intercom works/sounds. Good luck.
