My use:
To listen to music on my PC to send to my sound system.

Choices: Ease of use is plug and play. Tested in Win XP Pro 32 bit and Seven no difficulty in both cases.

I was looking for a small mixer USB power added one or two microphones.

UTILIZATION

Generic windows USB drivers.

Not yet tested for use in a DAW.

SOUNDS

As stated earlier no problem installing.

For the config, if it knows how to use a mixer is not very difficult!

I have not opened the manual.

OVERALL OPINION

Received today.

Tested his arrival. Not tested the preamp. For use as mine, it must send a sufficient level of PC for not having pushed the hand of the volume pot to its limits (creates a bit of breath to run and put a lot in the last quarter.

The pros: price, plug and play, the overall quality.
the -: no 2 track input to easily add a CD, MP3 ...

I would do this safely select for my use.
