When trying to record a mix from my vinyl turntables, to my laptop, I'm getting heavy distortion, especially during the heavy bass sections of the mix.
I'm running my turntables into a 3 channel mixer, then outputting via RCA "Record" ports, to a small headphone jack into my laptop's microphone port.
My mixer is a Numark DM2050 3 Channel Mixer
I've tried using Windows Sound Recorder and Audacity, but these both produce heavy distortion.
How can I avoid the heavy distortion caused? Someone has told me I'm supposed to use "line-in" on my laptop, but I only have headphone and microphone ports. What is the difference with "line-in" and is this what I should be using?
