Instrument preamp and dual mono transistor, there is a lamp for fun.
It amplifies!
Indeed until now I used the preamps of my sound card (Scarlett 18i6), it does not have much to see ...
There converters and SPDIF digital output.

UTILIZATION

Easy to use, nothing special.

I liked the default settings to démmarrage machine can be defined, which will save me 2 sec each time, but this is just details.

There is still a true default:
The signal first passes through a transistor amp and a lamp and a second small amp transistor.
The level LED indicates the level after the second transistor amp, so far ok, it can manage its levels out of the machine.
The problem is that there is no viewing level before reaching the lamp, therefore impossible to know how it is close to the saturation of the light (which is not very pretty, it has more the sound of a saturated transistor that lamp), which spoil some taken.

SOUND QUALITY

The sound of the lamp is not very interesting.
The sound made me look good, but I have not tested many external preamp is the same one I used.

OVERALL OPINION

I use it for about 6 months, I did not try the other model by the preamp of my sound card.
I like the digital output, the ability to amplify an honest manner (not like the basic sound cards)
I do not like the light that saturates when I not expect, and that bothers me to adjust the levels properly.

I remake that choice or price I got: 350th on clearance, which gives it a very good price / quality ratio.
