This device has two sets of inputs and one set of outputs . You’ll need one set of inputs and two sets of outputs like the rs-2. Where is your trigger coming from?I have a DAC with XLR feeding my headphone amp in my office and I'm going to be adding powered monitors to my setup. I assume this would be the type of device I need? The price seems excessive... but I probably don't need all the features since a manual switch would be within my reach?
