"The UCX's are connected to the computers via USB. But there are two UCX's per machine, and those two are connected via ADAT to each other which multiplies the outputs and inputs available to each USB connection as you now have two interfaces for each machine. So 4 total UFX's split into two sets working in tandem, one set per machine," said Tycho in a reply on Facebook, outlining how the UCX is used in his setup.more
Often people ask: How does this interface sound like? RME did the best job to make it disappear behind your signals. The UCX brings enough inputs and outputs to wire up all your project studio gear and comes with a great routing and mixing program that lets you set up individual monitoring for headphones and all outputs.
The DSP effects are great for low-cutting a mic, compressing a headphone mix or putting some reverb on the no-latencie monitoring for your singer. It's also possible to reloop computer intern signals to an input, so you can record the funny sample you found on the net.
Best working interface I had so far.
