Problems Recording DJ Mix


I’m using HP envy 14 notebook PC with serato SL2 and I’m trying to record a mix but am having trouble recording, I have a RCA cable running from the microphone port on my PC to my mixer (Pioneer DJM 250) using its 2nd Aux space on the back.

My mixer is connect to my 2 technics SL-1210mk2 as well as my marrantz pm6004 amp

I am using audacity 2.0.5, I have my stereo mix set as default for my recording device in windows settings.

In audacity I have the audio host as MME the playback as Microsoft sound mapper, the recording as stereo mix and the line in as 2 stereo input channels.

When I record I get really a quiet recording that’s fuzzy

Yet I can play music from my laptop through my speakers using the RCA from the laptop to the mixer and the sound is perfect.

Any help would be greatly appreciated.


Not recommended.
A typical microphone signal is around 1000x smaller than “line level”. The signal from a mixer is typically around “line level”, so it is likely to massively overload a mic input and cause bad “fuzzy” distorted sound. You need to connect the Aux to a “Line” input. Many laptops do not have a “line in”. The usual solution is to use a USB sound card that has stereo line in connections. I use a Behringer UCA 202 with my mixing desk and that works very well for me. Other brands and models are available.
