Prampli lamp with input and output jacks + XLR, SETTING THE gain and output level, gain boost of +20 db, since nitre-level output, LED cliping in between and a selector presets legalization (lgres).

UTILIZATION

I use it to plug my electric guitar on my computer.
I have a little to get galr SETTING THE Idaux levels between the gain, the output from the sound card, etc ... but we can not say whether complicated just plug and turn buttons.
The unit is quite heavy so it is well on the table, this is something that m'inquitait just seen the number of cables connected to the gizmo.

SOUND QUALITY

I find it fairly neutral. In my use (electric guitar), I find it leaves a little as it sends prs (with just the pramplification). The Difference diffrent positions show quite small, some are just saturate the previously well an rgl.
I am not as the creature did what I bought it pre-amplifies my guitar. But those looking to possibly variations in sound thanks to the selector will no doubt due, unless it is DIFFERENT on other types of sources.

OVERALL OPINION

I've had today, and I do not regret having bought. But as I have no other exprience on this type of product, I can not say whether it is better or worse than another, or if the price is justified.
Me anyway, for now I like it well this little gadget
