Tascam DR-40 has two external mic inputs. I believe I can record two stereo tracks on each input. I've been plugging in an XLR microphone into each of the two inputs and recording a podcast with two people. Then adjusting the audio in post.

But now we have a third person. I would like to add a third mic such that I get a separate (mono) track recorded for them as well. I imagine it's possible to "split" one of the inputs to the DR-40 such that one mic records to the left channel, and the second to the right channel. Is it possible? What's the (physically) smallest device that can achieve that? I know a mixer probably can, but that requires dragging around a mixer.

Sorry, I'm a total beginner to this. Because the podcast is on the move, I'm looking for the smallest solution. Here's the podcast (one episode is up) if you want to listen to the sound. It's taped in a gym.

The DR-40 is a four track recorder, but only if you count the two built-in mics. You can have at most, two external microphones. BTW, XLR inputs are inherently mono.

Record the built-in microphones with the XLR mic or line input for a four-track recording

Emphasis mine. From the website

I think it will still suffice in your three source situation however.

I would hand an external mic to both of your guests, and use the built-in mic yourself as the third. At least that way, you will be the one in control of the recording unit.
