I am wondering about my options for adding a 3rd analog output from my computer for a subwoofer. For my secondary office setup I am using a Behringer UCA-202 to output analog stereo to a 2 channel amp, feeding my desktop speakers. I am going to be adding a subwoofer, and would like to be able to control the crossover, and perhaps some dsp within JRiver. As it stands now, I have no 3rd analog output. The plate amp i will be using has speaker level inputs, but that doesn't give me the xover/dsp control I want.
Would it be as simple as adding a second UCA-202 and directing the subwoofer signal to one of its outputs? Without a second soundcard on hand I can't verify this possibility, and the Audio Device menu doesn't suggest that this is an option. Any advice is appreciated.
Thanks.
Ben
