Digidesign Mbox USB A/D D/A digital interface

Very good condition, came from a working studio, guaranteed not to be DOA.  If memory serves, Pro Tools is required for use with this interface.  Interface only, no software or cables included.  

These specs may have changed, from the web:  

The front panel of the M Box 2 Mini features:

• Stereo quarter-inch headphone jack socket.
• Monitor/headphone volume control.
• 'Mon Mute' button: this does what it says, muting the monitor outputs on the rear but not the headphone output on the front. This is a new feature for the M Box family and is very useful for preventing feedback in the monitors when recording with a microphone.
• Mix control: this gives the same zero-latency monitoring as its counterpart on the M Box and M Box 2, balancing the levels of input and playback signals at the output. It's a shame that this control is not more clearly labelled, though.
• USB indicator to show that the M Box 2 Mini is powered and connected to the computer.
• Level controls for inputs one and two.

On the back panel we have:

• Two analogue inputs, but only one suitable for a microphone. Input one has an XLR mic input with 48V phantom power option. There's also a mic/DI switch and pad, which I found slightly confusing at first, as the mic/DI switch selects either the XLR and the jack input, but the pad works on both the mic input and the line input.
• Input two is a DI or line and has a pad switch to select between these two input types.
• Stereo quarter-inch jack outputs. There are no fixed line-level outputs on the M Box 2 Mini, the monitor output jacks are fed from the monitor/headphone volume control on the front panel. As with the rest of the M Box series, the signal level of these outputs is lower than the normal professional level of +18dBu for 0dBfs.
• USB port.
