Even in the Windows version, although you can find a switch to determine +4, Consumer or -10, these are just faders as well. The so called 'switch' just makes the faders jump to a predefined fader value. So you can still finetune those settings. And btw, IIRC the +4/-10 switch only works for the first input pair (XLR). But I'm not sure about this, I'd have to search the manual to be sure. >And thank you for your tip with the alsamixer.

The one which has me the most puzzled is the 'Volume Change Rate' in the 'Hardware Settings' tab. > In terms of sound quality, is it bad to amplify the input signal via the > Delta1010lt (with adc set higher than 124)? IIRC, 0db on the control panel is always '0dbFS (Full Scale)', which doesn't correspond to 0db VU in the analog domain. So there's absolutely no need to go exactly (or even too near) 0db. Leave yourself a little headroom so that you're still able to process your audio after the recording process. Digital clipping really sounds nasty to my ears. You can hear it more and more often in audio files downloaded from the net, and even on newer CD releases sometimes. But there are people on this list (Fons, Paul Davis, Norval, Dave Phillips, Ken Restivo and many, many others) which can surely give you better replies and/or scientific explanations on the subject. > Thanks for your help, > Markus You're welcome, Raphael ;) _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
