In XLR mode, the interface owns the headphones and monitoring. USB mute and processing do not automatically affect the XLR signal.

Choose it if…

  • You want a direct USB computer input without a separate audio interface.
  • You want to hear your own voice through headphones while you play.
  • You can match your stand or arm to 5/8-27 thread · Adjustable arm mount · Removable desktop stand.

Before choosing this model

  • USB and XLR have different controls. Select the connection in the checker; do not assume USB mute or DSP reaches the XLR output.
  • Check the stand, thread and desk position before ordering a mount. Include attached shock mounts and adapters in the total weight.
  • Check the included cable against the available data port. Add only the adapters or headphones your chosen path needs.

  3. Check speaking level and mute with headphones on. Change only one gain, sensitivity or suppression control between tests.
