Re: [xl7] recording from SPDIF output?

2003-04-22 by Kris Musard

I am using the MP-7 through a Tascam US-428 to Cubase
5.1.  I thought something was wrong with my setup at
first because the recordings had no waveform.  After
about 30 minutes of fiddling around I hit play and
heard that they actually did record.  I had to stretch
the display to its maximum track size just to see a
little bit of waveform.  Thats when I normalized the
recordings so that I could see the waveforms for
editing.  I did not notice any additional noise, but I
just wanted to see if anyone else has experience with
this.  If SPDIF does not have a noise floor I think
that it would be simpler and quicker to just normalize
everything on the PC rather than adjust each preset
manually to get a hot signal without clipping.  It
also saves preset slots for me since sometimes my only
modification is to increase AMP VOL.
