UTILIZATION

The utilisitation is simple, no need for manual, just a good ear.

SOUND QUALITY

The big disappointment:
End of the first trial was extremely disappointing. In fact, I had a blast unbearable CONVRS the entire signal.
Troubleshooting:
I had not perceived that I had forgotten to turn phantom power off ...

Now that everything is in order, I find it just as it tends to blow, but this is certainly due to the fact that the signal to the input is not adequate.
Regarding the effectiveness of the equalizer, there is nothing to criticize. It's really effective.

OVERALL OPINION

I use it for a few days.
I will say more in a few months.
