fons, gene,

thanks for your insights, particularly about the problems of AC rms
meters at audio frequencies - i was totally ignorant of this, and i'd
have shot myself in the foot with this eventually.

fons, after i read your remark i asked around, and yes, the ff800 does
indeed use servo-driven outputs, so the voltage difference is
intentional and no cause for concern. i'll definitely investigate the
level differences between channels, but as you said, i'd better do that
with a sound card rather than a meter.

gene, would love to follow your scope advice (particularly for the
beneficial effects on gonads), and i'm looking out for one, but i'm not
really prepared to pay much. in any case, it's way sexier than one of
those usb sampling gadgets sold for a scope these days... maybe i'll
find a nice, simple one in a dumpster somewhere.

nice to get you two guys into another discussion about signal
transmission - very instructive!

best,

jörn

btw: yes, the folkwang address seems to have expired at last. the la*
lists were the last things i used it for, and i have now resubscribed
from my own mail domain. so please ditch that old one from your address
books if you want to get in touch off-list.
