Hi

I bought one for I88X m 'ADAT interface with my AW4416, that was the only sound card and ADAT 16 channels for a reasonable price: 500 euros in Playback
It is connected either on my Mac mini with panther in Logic Express 7 or in stand alone on my ADAT by AW4416

UTILIZATION

Installation:
1 hour to download on the Yamaha website has the driver days
2 minutes to install
30s to start autoconnect
and after we play and we forget
No problems installing or operating

GETTING STARTED

No malfunction or stability of drivers
the plugs supplied (after updating Internet) are friendly and very musical
I have transferred projects under adat and no problems
I have tested the pure audio config and no problems

OVERALL OPINION

I have since 2 weeks and I love the direct monitoring
The sound of the first 2 tracks are very good, better than my AW4416, the other channels are in the middle, largely as good as my AW4416

My mini mac n 'bear in the second one probably not, but for my AW4416 I will be buying a second to replace my 2 racks / O ADAT.

Small edit after 4 years of faithful service is now connected to an iMac and Logic Studio 8, and still no problems
never stall, never the slightest glitch.
I give 10 as a note because even though the specifications appear to date it remains an incredibly stable map, after 4 years the pots do not even crachouillent, latency: 18 entries to 2ms latency!! . Only regret is the lack of worldclock
