Selecting the USBPre in Mac OS

The USBPre communicates with the Mac OS operating system and audio software through Apple's USB audio support in the Sound Manager. Audio  applications that communicate with Mac OS through the Sound Manager can use the USBPre for recording and playback. The USBPre functions as an outboard audio interface and does not require any built-in audio hardware to function.

To select the USBPre in the Sound Control Panel and test its connection:

  1. Connect the USBPre to the computer.
  2. Open the Sound Control Panel from the Apple Menu.
  3. Select Input settings.
  4. Select USB Audio (this is the USBPre). It will default to External Mic as the Input Source.
  5. Connect an audio source to an input of USBPre and select its input type via the front panel input selection buttons on the USBPre.
  6. Verify that the front panel level meters are responding to the audio.
  7. Select Alert Sounds, and record a sample alert sound to verify that the USBPre is recording to the computer.
  8. Play back the audio to verify that it has recorded.

Note: Do not plug or unplug the USBPre when actively recording or playing through the USBPre. The application and the operating system may become unstable. Unplug the USBPre only after exiting out of audio software.
