Are you trying to connect your cellphone to an audio mixer so you can have a two-way phone interview for your radio show, podcast, or live event?? In this article, we’ll explain exactly what you need to do to achieve this.

Quick Answer: Use a headset adapter cable to send audio from your mixer’s aux send to your phone. The same adapter also returns the phone’s output to your mixer for live monitoring, broadcasting, and recording.

Headset Adapter Cable

With this solution: 

  • The person on the other end of the call will hear what the presenter is saying through the studio microphone.
  • The guests in the room with you will hear the caller through the in-person sound system. All without creating a feedback loop!

The key to making this work is a headset adapter cable. It looks a little bit unusual, but it gets the job done. How does it work? We’ll quickly explain what the 3 connectors do.

  • TRRS: Connects to your phone as if you were using a wired headset.
  • XLR: Sends mic audio to the phone from an aux send on your mixer.
  • 1/8” Stereo Output: Delivers audio from the phone to the mixer.  

How To Connect Phone to Audio Mixer for Phone Call / Interview

Time needed: 5 minutes.

  1. Connect headset adapter to phone
    Plug the adapter’s TRRS connector into the headset jack on your phone. If your phone doesn’t have a headset jack, you’ll need an additional adapter. In the case of iPhones, use a lightning to headset adapter.
  2. Connect mixer aux send to headset adapter XLR connector
    If your mixer has an XLR aux send, plug in the adapter’s XLR cable. If your mixer has a balanced TRS aux send, use a TRS to XLR adapter to link them.
  3. Connect headset adapter stereo out to mixer
    Use a 1/8” to dual 1/4” adapter to connect the headset adapter headphone jack to a stereo pair input on your mixer.
  4. Aux send settings
    Turn up the aux send level on the mixer channels you want the person on the phone to hear. Make sure the zero the aux send for the phone audio return channel to avoid a feedback loop.
