Analog Converters => digital and Numrique => Analog
The analog input / output jacks are symtrique 6.35 mm
Inputs / outputs are on numriques standard ADAT optical fiber
The case and a 19 1/2rack "a unit!
It has also taken on the 2prampli micro combi jack / XLR, rglage gain and phantom power supply gnrale.
There is a 3 position switch that allows the conversion rgler A => N to 44.1 kHz or 48kHz (Adcon is then in the master) and a position AD / DA (the Adcon is a slave)
I put 9 because there is no ON / OFF.

OVERALL OPINION

I use it for one week but I'm 3 days and 3 days of mixing taken since I have.
It is perfectly in sync with my RME Multiface I, and 16 analog inputs / outputs. I did not not of difference between a track recorded directly into the RME and even converted by Adcon.
I could not compare with other models converters.
In the beginners I wanted to buy a behringer ADA8000 ULTRAGAIN but as n'tait in stock and j'tais prss MODEL I took the only stock and in my budget. I am fully satisfied.
I put 10 as it is, IMHO, trs a good product for the price.
