It will mostly be a difference in output level of the microphones but
there may be some small difference in the character. If the Revox mic
is truly a rebadged M201 and not a microphone make for Revox, it may
be possible to change its output impedance by changing a tap on a
transformer inside. I've never been inside one, so I don't know for
sure, but it's worth a look. Otherwise, just use them as if they were
two different mics that sound pretty much alike.

Once you figure out how to take them apart (start at the XLR connector
end) you might find the wiring differences and find a different tap
on the transformer that you can use.
