For specifications, see below, I have nothing to add.

if, may be sorry to have only two XLR inputs, but hey, for the price, do not push it either

UTILIZATION

Using ultra simple and intuitive ...
I do not have the user manual in French and I got out quickly.
when I got there, it means that even a hamster can do ....

SOUNDS

Nothing to say, it's super clean, and the effects of quality
the preamp may be a bit low for a voice ..

OVERALL OPINION

I use it for several years on tour, such as personal return table
I take great care, and I never had any worries, it is very reliable.

I really like the ergonomics, size, robustness, its comprehensive functions.

before 3100, I walk with a rack for the reverb (quadraverb2), a mackie (1402vlz pro) etc ... Now I have more than that and besides, it sounds better ...
I tried tables fostex digital ... beuahhh is worth avoiding so it sucks ...
I have since 3100, my pro 1402vlz stay at home and take dust, it is to say ...

the price of this little gem is more than interesting especially cars on Audiofanzine.

I remake this choice without hesitation, have pity there is no intermediary between 3100 and 7100.

I am so glad I bought another (pro version)

pity I can not make 20/10
