I have some nice Grado headphones for monitoring, but becuase much of my voice-over work will now end up being distributed as streaming Flash audio, I'd like to listen to the mix on cheap consumer desktop computer speakers as well -- the kind of thing that comes bundled with a PC or that you'd pick up at Circuit City or Costco -- that's what most of my audience will have.

These computer speakers typically have a 1/8" stereo jack. But my new soundcard has 1/4" outs only.

Now, the lead-in, lead-outs, and background music are stereo. The voice-over is a mono track from a channel strip. So, the mix will up a single stereo track. Right?

So, I'm trying to figure out my options. I guess I could leave the old Audigy card in the machine and manually select it as the output device when I wanted to hear the speakers.

But I'd rather ditch the old card and just use the new one (Delta 66). So how do I physically adapt the 1/4" mono outs on the card to the 1/8" stereo input going to the speakers? Just a matter of finding an adapter or is there something else?
