GO:MIXER PRO X: Symptom: No Input Audio

The following article troubleshoots in the event that the GO:MIXER PRO X is not inputting audio in order to record audio in an app.

• POWER
  • Be sure that the POWER light is illuminated green.
  • Make the connection between the iPhone or iPad and GO:MIXER PRO-X before opening the phone or any apps.
  • If the POWER light does not illuminate, there may be a connection issue. A common reason for connectivity issues is that the phone's USB port, lightning port or headphone jack has accumulated dirt, lint or dust that is preventing the GO:MIXER PRO X from connecting. Check with the phone manufacturer for information regarding properly cleaning this port out--in order to make connectivity.
  • Be sure that the phone is charged and not low on battery.
• COMPATIBILITY
  • Be sure that a compatible phone is being used:

    (Scroll down to "Support Documents" and view one of the "Smartphone Compatibility" links)
  • Check that a compatible app is being used by referencing one of the "Smartphone Compatibility" pages from the link above.
• AUDIO SOURCE
  • Check that audio (such as music on the phone) can be played from the phone to the GO:MIXER PRO X and can be heard from headphones that are connected directly to the GO:MIXER PRO X.
  • If using a condenser mic, the PHANTOM POWER switch on the GO:MIXER PRO needs to be set to 48V. Note that the XLR input needs to be used if using a microphone that requires phantom power.
    • iPhone/iPad Users:
      PHANTOM POWER cannot be used when being powered by an iPhone or iPad. In this case, batteries will need to be installed, the BATTERY switch set to "ON" and PHANTOM POWER set to "48v."
  • If using an external audio device (e.g. guitar, keyboard, microphone) or a mixer, be sure that the volume of the external device is turned up on the device itself.
  • Test with a different audio source (i.e. a different microphone, audio device, etc) if one is available.
• CONNECTIONS
  • Be sure that only the included USB cable is being used--3rd party cables are not recommended.
  • Disconnect the USB cable from both the GO:MIXER X and the phone. Then reconnect both ends making sure that the USB cable is fully connected to both the GO:MIXER and the phone.
  • Test with a different audio cable (if applicable).

If the issue continues, test with a different compatible phone (using the link of the article above as a reference) to determine if the issue is due to the phone itself.
