Two sound sources - one set of powered monitors

[thermsb]

I have an Mbox 2 and want to A-B with CDs. Of course, since the ASIO drivers only accept one source at a time I have a second sound card for CDs, mp3 etc... and want to CHEAPLY route the signals from both sound cards to my Event ALP5 monitors whick only accept one input (balanced XLR L/R). SO, long story short I am looking for a device (hopefully NOT a full blown mixer) that I can feed two balanced (four TRS cables) and have it output one balanced signal to my monitors. Any product or suggestions on solving this issue?

Thanks - this board is amazing!!!

You can go with an easy stereo A-B switch (you can probably build one with parts from Radio Shack) or go with something more elaborate like the Presonus Central Station (~$499.00) or Mackie Big Knob(~$279.00). There are others out there like the Samson C-Control (I think that's the name of it) for ~$99.00. I think Grace Designs also make a high end unit that does this.

Are you trying to listen to PT and A/B it against a CD? If so you could always browse through the Workspace window to the CD and listen to it through PT.
