Yes, in two different ways. The SF-12 sums to mono extremely well, so you can combine the outputs of both channels into one channel for a mono track. Or, being that an SF-12 is made up of two identical mono ribbon elements, positioned one above the other, you can use either side of the SF-12 as a mono mic with no negative effect. The mic cable is labeled "Upper" and "Lower", so just plug in whichever ribbon transducer you'd like to use.
