UTILIZATION

The configuration could not be easier! Not need the manual ...
Out of the box connect, test, and off you go!

SOUND QUALITY

I use it to amplify my microphones and instruments before going into my sound card Terratec Phase88.
The sound is very clean and I see no breath!
I do not have to get the gains to get a good reception (Some milimettres enough).

OVERALL OPINION

I use it for two weeks just so I can not give advice on longevity.
What I like most is the price! € 150 is really not steal!
Then the phantom power on each track separately controllable it is still the foot!
What I like least? ... Heuuuuuu ... Beinnn heuuuuu ... How to say ... Knobs may be plastic but hey, I do not see what the problem is ...
Before using this preamp, I used a Behringer Eurorack mixing desk, which broke down 3 times and whose control of the phantom was small (two point) ...
Frankly this preamp is really worth!
