Hello. Currently I have a ********* Control2USB monitor controller with 2 pairs of monitors and a sub-woofer. I also have an Amazon Eco Device hooked up to one of the aux inputs of the controller so if I want to listen to music there, I can without having worry about levels being off of even having my computer on.
I'm looking at the Central Station with controller to replace the Control2USB to free up some desk space. If I run my main sound card (in this case a Scarlette 18i20 3rd gen) to TRS 1 or SDPIF, could I connect my Amazon Echo to the Aux and have the aux signal run in parallel with the main sound card signal for listening to music and playing along?
