Convert stereo analog / numrique, AES / EBU or S / PDIF or ADAT (MODEL the current is more complete than that in the photo). The volume knob can be bypass via an internal switch.

OVERALL OPINION

I use it for over a year. The look is not very pretty, size 1 / 3 rack impractical. I do not care: the sound is excellent and that alone is important.
It is simply the converter as neutral as I know. Price intressant.
I availing oneself of other converters quality but I think the Mytek is more neutral.
