Tube compressor ..
Setting standard compression treshold / gain / gain Makeup. 2 switches for the release and attack. (Soft / hard)
An input gain and output gain.
A gate.
Jack and XLR connectors plus a side chain jack.
OFF switch facade
Analgique saw two meter needle

UTILIZATION

Simple config.
finer adjustment of the release and the attack would have been a plus.

SOUND QUALITY

for sound: quality = in sound quality ++.
no miracle, it does not change poor sound quality fighter.
first impression:

no difference to the ear (except an adjustment with a high treshold)
and ears become accustomed and smell the nuances. a very sweet very musical compressor for my taste,. The lamps have the ability to soften the sound.
A battery, perfect in Overhead or atmosphere.
Snare = ok for pop jazz blues
Snare = ditto
all except strong adjustment of treshold
do not expect a huge pumping, this is not the first quality.
The voice, it helps to bring out the mix (provided you have a quality decision I repeat).
Acoustic guitar in arpege ok in struming less on
Electric guitar: same.
After adjustment with a strong, we can do cruncher with a strong gain in face of gain guitar amp and management out as a volume gain amp. this is cruncher harmonics.
This is not his first vocation but the effect made to smear the sound is not unpleasant.

OVERALL OPINION

provided for use in studio home studio for 4 years.
very different from the pluggin I use (wave ... etc).
I remake that choice for that price ....
