Sir, your answer is in worth of gold! I have never heard my recordings in this kind of quality! I really appreciate your answer!
For someone reading this you need to set AudioBox as a recording device in your PC. I use Audacity and everything seems to work just great by following the steps shown in the answer! Just one more question to make things more clear:
Can I use DJM 800 outputs with XLR cables for my Booth monitor speakers NOT AudioBox output (TRS cables). Does something change if I'll use AudioBox output for Booth monitors instead of DJM output?
Just recorded a small sample with the way I described here but I can hear a little distortion on Kick sound in a track. Could it be because I did not use AudioBox as a output (the input levels did not peak)? And what does the 'vampire tap' mean? Will AudioBox act as vampire tap only in case if I use it as audio output for Booth monitors?
Thanks in advance!
