I'm not sure but I expect that some do.

An alternative explanation for the reduction in volume:
It's possible that in your case the Left and Right channels are getting
slightly out of sync. with each other somewhere during the recording
process.  To see if this is the case you could record in stereo from a
source with two identical channels and then do an L-R comparison after
recording to the MD.  If they were out of sync. then this would tend to
reduce the amplitude causing what you are observing.

I've found the best way to do monaural recording is to unplug one of
the RCA connectors (for a tape recording whichever has the lowest
recording level-- there is generally some discrepancy 'tween channels)
and take it from there.  No L/R interference, easy to set up, worked
fine with an audiobook (better than letting my R3 convert the two
channels into mono).

Is the volume OK (maximum) - if so, the recorder is probably averaging the
two input levels to get a mono signal.

It's a pity that this isn't very easy with SPDIF :)
