It is a tube preamp
it has a phase reverse, limiter and of course a phantom power supply.
can enter and exit XLR or jack.
as is a small box, it is not rack

UTILIZATION

Simpler, we can not, you plug and it works, it lacks an on / off button but hey you can not have it all.
I use it just for the phantom power supply and it served its purpose.
The manual is clear.

SOUND QUALITY

I have often heard that there was breath and well with this box, I do not even know what the word means breath: there is not the slightest breath coming out, even the sound of back of my sound card is gone!
So, I'm an angel, that stuff is perfect!
for coloring, I do not know because I never used my microphone no.

OVERALL OPINION

I've had four days.
the +, simplicity, and (for me) the quality of its output
the - for what I did, no -
this is my first model but is excellent value for money, to do over time.

So I do it again because this choice for the price, the result is!
