USB-B Interface Specs

Hey there!

Loving the cq20b!

I was looking for the specs on the USB-B interface and I am not finding them. I’m probably just overlooking it somehow.

What is the max resolution? I see the fx engines are running at 96khz, but what about the USB interface? 44.1? 48? 96? 192?

What is the max bit depth? 16? 24? 32?

What is the latency??

How would I find all of this out?

Thanks!

Chris

Latency is a harder one to answer - it very much depends on your system and what you’re doing with the signals. I would expect anything between 7-20ms to be fairly normal for a USB round trip - but it does depend.

Thank you Mark!

I was pretty sure it was in there.. I apologize for missing it and I appreciate the quick assist!
