All it says on the product page.

But there is no exit / entry format digital cinch in addition to optical already present.

UTILIZATION

C simple just follow the doc, a couple of points to follow in the documentation provided and that's it, BUT ...
I had a problem, well yes, if that was too easy.
At the end of the installation of the driver interface switches Firewire disabled on the PC without being asked, to address this problem, simply go to the Device Manager and activate the device firewire interface in networks , after my memory and after more problems for life.

My PC is a Sony VAIO FS285 Laptop, Centrino 1.7GHz, 1GB RAM

GETTING STARTED

It is simple, even if the product is complete.

The on / off button is not very practical, AC was already said here and confirm.

Otherwise it looks solid all levels and it is small and well finished.

OVERALL OPINION

The sound quality is very good, not far from pro.

I tried the digital input, noon, analog inputs and I have not had a single worry or disappointment at the sound.

I did a lot of making his guitar => Strato US => amp lamps Mesa F30 => FA66 => Laptop / Sonar 4
And that makes him very well ...

It is in competition with the M-Audio Firewire 410 but you it seems boiboite satisfies me.
