OK, now I'm REALLY confused.
From what I've read on the reflector, and what others have told me, it
is OK to insert a mono plug into either the front or rear phone jacks.
It was also made very clear that inserting a mono plug into the rear
SPKR jack was a big no-no, even if the settings were set

Hi Don,

Hi Ken,
That is not my intent. What I'm trying to do is combine both LR audio

output is also mono. I then want to be able to connect my stereo

Hi Rick,
I would suggest the Keyspan USB to Serial adapter over the KUSB. With the
KUSB, I always had problems with it when using programs like HRD or DM780.
I believe that was due to the drivers being used. OTOH, the Keyspan unit
works very well and does not seem to add any additional noise
Don, yes I do recall now that the drivers were for the Prolific chipset.
That cable never worked properly for me, and I ended up ditching it in favor
of a Keyspan which uses the FTDI chipset.
