Re: Weak SPDIF signal

2003-09-27 by vibesart

My understanding is that the baseline level for the SPDIF signal is
set where it is to allow for the extreme bumps in level that can occur
when employing various quantities in Resonance thru the filter
section. If you play around with those features (filter.freq.res.) you
will hear what I mean. Since it is a 20 bit D/A there should still be
plenty of quality signal there - but you may have to adjust it with a
digital mixer function - whether in or out of the DAW. However - thru
a good gain stage and converter the analog signals sound great. Thru a
bad converter they will sound....bad. The stuff that I tracked from a
Command station/P2000 thru an Apogee converter sounds really fantastic.
