Pro Audio Support

Q:
My MBox2 powers off or loses communication with ProTools when I enable phantom power. The Mbox2 is connected to an Apple Powerbook.
 
A:
Phantom power should only be engaged after the Mbox2 is connected and Pro Tools is launched. If phantom power is on when the Mbox2 is first connected to the CPU, it will drop offline. So in these cases, the following steps are encouraged:

1. Connect the Mbox2 to the USB port with PHANTOM POWER OFF
2. Launch Pro Tools
3. Connect any phantom-powered microphones
4. Turn phantom power on

These steps should keep the Mbox2 online.

This issue is normally isolated to specific PowerBook models. Detailed information can be found at www.digidesign.com
