Duet 2 ships with a peel coat on the top panel to protect it during shipping. Be sure to remove the peel coat before operation.
There are several remedies for audio that is distorted, choppy or otherwise compromised:
1. Hotplug Duet
2. Toggle sample rate (in your DAW or, in the case of iTunes, Audio MIDI Setup)
3. Reload DAW driver (for example, in Logic choose Logic Pro > Preferences > Audio. Click
on the Devices tab, then the Core Audio tab. Uncheck Enabled, then re-check it.
4. In iTunes, stop then re-start audio playback.
1) Verify the unit is properly connected and recognized by the Mac. You should see 4 icons on Duet’s OLED (input 1, input 2, speaker out, headphone out).
2) Select Duet USB as your Mac Sound Output device in System Preferences/Sound or in Audio MIDI Setup (Applications/Utilities).
3) If you have chosen Mixer for the output selection in Maestro, then the Software Return fader must be raised to send audio software application outputs to Duet’s outputs.
On the Input tab of Maestro, be sure to set Analog Level to Instrument (Inst).
When the inputs are set to XLR line, the encoder is disabled.
The white “A” indicates that USB is disconnected. Connect USB, try a different USB cable or a different Mac USB port.
