I can't hear my voice while recording vocals with MBox 2 Pro

[ruper]

Hi all:

I was using an old MBox and I didn't have any problem to adjust the volume in the headphones higher than that of the mix, so that I could hear my voice while I was recording a vocal.

I recently bought an MBox 2 Pro, and I have not been able to figure out how to hear my voice louder that the mix in the headphones. If I turn the volume of the headphone louder then the mix also goes louder and I can't still hear my voice.The result is that I go out of tune since I can't hear my self.

I was thinking to buy a small mixer to blend the two headphone outputs (A & B) into a single one, but sending the output of the track where I an recording the vocals to, through the Output 3-4 at Headphone B.

How do you go about this with the MBox 2 Pro without having to buy extra gear?

There must be a simpler way to do this! It was so simple in the old MBox!

Thanks in advance for your feedback
