I also have a BC780 and someone commented on the Tape Out jack
being constant volume at line level. Unless I accidentally plugged in
to the Speaker jack, I thought I remember that the Tape Out jack
volume varied with the Volume control right along with the speaker
output. I feed speaker audio in to my computer sound card, but I just
set the volume control and try not to bump it later. The only other
thing I remember is that you have to enable the recorder output on a
channel by channel basis. If there is a way to get a fixed level out
of that jack, I may revisit its use as it would make setting up the
computer to record much easier.
