Question about playing stereo wav files on mono channels

Sorry if this was covered somewhere - I looked!

How will the S2400 handle wav files in different formats? In particular, I have a lot of 16 bit “stereo” drums samples that are really the same in both channels. How will the 2400 play those on mono channels? Sample rate convert? Mono-ize them? Pick one channel?

Thanks! Can’t wait to receive mine.
