Can I bypass the preamps in Duet 2 (USB)?
YES! Duet 2's preamps can be bypassed if you'd like to connect a line-level input source such as an external microphone preamp or mixer.
Here are the two things you'll need to do:
- Connect the device's line level output to Duet's combination input jack using an XLR cable.
- Go to the input tab in Maestro or Apogee Control 2, depending on which software you've installed (found in your Applications folder), and change the input selection from "Mic" or "Inst" to "+4 dBu" or "-10 dBV".
The line-level selection will depend on the type of gear you're connecting. Professional audio equipment most often uses +4 dBu, while consumer audio gear is set to -10 dBV.
