I'm using this together with a Tascam US20x20 to get 18 Line In, instead of the 10 that the US20x20 provides.
At first i was confused because ch.1 on the unit (what i believed to be digital channel 11 when looking at my Tascam Inputs) did not give out any sound. What i should have been connecting internally (Cubase) is actually digital ch.13 since ch11-12 are coax.
Overall it was very easy to connect, i was expecting the routing etc to be troublesome, but so far it works well and the sound seems excellent. Recommended.
