Projector

More than likely your setup has a cable plugged into the Audio Out port on your projector which takes the HDMI audio in, and sends it to your speakers. You will need to split your audio at this point using a 3.5mm Audio splitter.

You will:

  1. Remove the audio cable from the Audio Out port on your projector

  2. Plug the splitter into this port

  3. Plug the audio cable that you removed into the splitter - this will reconnect your speakers to the projector

  4. Connect your audio cable for the FM/DM system to the splitter

  5. Plug the audio cable into the FM/DM transmitter.

You may need a longer cable than normal for this, especially if this is a permanent installation.

This is diagram shows the end result that you should end up with in this scenario.
