My choice for a 400 was for the quality of its converters
With Class A preamp, 2 Mic XLR jack that accepts mixed neutrik jacks, 2 between LIN / INST + 4 + 6 sortieligne line inputs and headphone output, MIDI X2, ENT / SORTSPDIF, Word clock and a superb mixer on virtual computer

UTILIZATION

Exelente a sound card with a stable driver and often updated, attention has updated the firmware (program of the case of RME) poor manip little screw up, exelente low latency but needs a good processor

GETTING STARTED

A manual clear, use relatively easy you will not Sousse

OVERALL OPINION

it's been over three years that I have and I'm delighted
After the M-Audio Delta T 1010 is the day and night, also the 2408 motu which was more specific MAC and I Prefair the RME, which has EXCELLENT converter which for me is vital for a sound card, a Class A preamp which is not bad and you will be useful
a good quality price with a little less on the firmware or install a engoisse I always make a bad manipulation, which could make the RME dead, what happened to me once arriverune
