Although I am well pleased with the audio and build quality of my new
PreSonus FireBox, I am having trouble recording with it.

Everytime I put a mic on, I get extreme pumping of the level. It cuts
in and out in an oscillating wave like a compressor on crack. What can
I do? I've tried lowering the levels and different Fs, all to no
avail. Am I doing something dumb? It does it with both of the
programs I've tried it on, haven't tried it on Vegas yet.

I use a Dell 8100 PC 2.8P4/1GB with XP SP3 with Sound Forge 8 and
Cubase LE. I also have an Audigy2ZS PP but I got the FireBox for
proper balanced inputs.

Any ideas anyone?

TIA,
