Prampli is a lamp (12AX7B).
There is a gain and output volume.
Between an XLR Mic or Line in jack.
An output balanced or unbalanced on XLR jack.
A vumtre.

UTILIZATION

At first glance, it's super simple.
Well, the manual is in English, but normally the one who used the WO stuff sound understand the terms.

SOUND QUALITY

So the drama is, to quote another.
The blast produced by this machine is not the teacher, it is carrment unbearable, and makes its use impossible. I changed the lamp, has given nothing. I did 20 minutes heating before use, nothing.

OVERALL OPINION

I use it for two weeks. I had bought from Thomann, because I had hallucinated the price (44). Obviously, I never would do such a choice.
