If your main switching device does not have a headphone jack or Lightning port, you can route audio into the device using the USB-C port.

This article outlines:

How to Determine if your Device has a USB-C Port

The USB-C port is the oval-shaped port on the bottom edge of your device that you use to charge the device. Compatible devices and USB-C port locations are shown in the diagram below.

If your device does not have a USB-C port, you'll need to follow these instructions for using a Lightning port.

Required Preamp, Cables, and/or Adapters

  1. Preamp with USB output: A preamp is an audio device that converts an external audio signal into a signal that your Apple device can recognize.
  2. Apple USB-C Digital AV Multiport Adapter: This adapter will allow you to plug an external USB preamp into your Apple device while also charging the device using the factory charger and cable.
  3. USB-A Cable. Regardless of what type of USB output the device has, you will need a USB cable that ends with a USB-A tip.
  4. XLR or 1/4" TS/TRS cable: You will need either an XLR or 1/4" TS/TRS cable to connect an external microphone or mixer to the preamp. The type of cable you need will be determined by the available outputs of the mixer or microphone.

How to Connect an External Microphone

  1. Connect one end of the XLR cable to the microphone and the other end to the preamp's input jack.
  2. Then connect the USB-A Cable to the preamp's output jack. Connect the other end of the cable to the Apple USB-C Digital
  3. Connect the Apple USB-C Digital AV Multiport Adapter to the Apple device's USB-C port.
  4. Your main switching device will now recognize the preamp and connected microphone as the main audio signal for your videos.

How to Connect an External Audio Mixer

  1. Connect external audio devices like microphones and laptops into your mixer.
  2. Connect your mixer's output into the preamp's input. Most mixers have a section labeled "main outputs" that are either 1/4" outputs, XLR outputs, or sometimes both. Depending on which mixer you have, you will need the appropriate cable to hook into your preamp.
  3. Connect the preamp's USB output into the Apple USB-C Digital AV Multiport Adapter using a USB-A Cable.
  4. Connect the Apple USB-C Digital AV Multiport Adapter to the device's USB-C port.

Note: Many mixers have both Left and Right audio outputs for stereo, but many preamps are not stereo. By default, plug your output cable into the Left output of the mixer. Some mixers default to mono if nothing is plugged into the Right output. Be mindful that if you have a microphone or other audio signal that is panned to the Right and you are only using the Left output, you will not hear that signal on your video.
