Denon DN-S1200 Volume

Hi, I have a pair of Denon DN-S1200’s with the outputs recording into audacity. I am trying to find a way to reduce the volume of an individual device so i can do smooth transitions between 2 different CDs and scratch on one without it being too loud . For example using the pitch shift faders would be an ideal way to control the volume.

Using a mixer would be wise…

It certainly would, but as I don’t currently have one I hoped there was a temporary way around it. I can assign pitch fade as crossfader/master in Mixxx and that works fine but it only seems possible in MIDI mode.

How are you feeding two stereo analogue outputs into your computer?
