Prampli 2 channels lamp trs simple to use: + gain volume. Attnuation of 30db and phase reverse on each channel.
Connectors: XLR, line (as in and out).
Rponse in frquence: 20 - 40 000 Hz. Max gain 70db.

UTILIZATION

Terrible simplicity of use. It ajouste volume and gain and go.

SOUND QUALITY

I use this with a micro pramp Rode NT2, the quality is irrprochable. Same with my first micro (Stagg) 150 euros this pramp sone terribly.
The resulting sound is trs color (perfect for use as I do: making voice, sax ...). It will not suit users looking for a transparant his trs (percussion enregristrement ...).

OVERALL OPINION

I use it for over a year. It is the heat given by pramp, the power of the signal gain and noise lev trs are the main qualities of this machine. I did not test much more expensive hardware so I do not know if it a big gal Focusrite or whatever, but it holds up without problem before my TL Audio 5051.
400 euros for a second-hand report quality price trs interesting.
I do it again this choice without problem.
