Why do I get so much bass feedback when I switch to Live Input on Traktor Scratch Pro
When I play my timecoded vinyl on track deck mode in TSP, everything is fine, but when I play my real vinyl records and switch to Live Input, I get a shit load of Bass feedback, why is it like this? What can I do to fix it?
Have you tried different needles?
Play real vinyl through DVS and you shouldn’t get that problem…just map a button to change deck to live input so you can record mixes with real vinyl too…
There is a slight difference in output volume which is most likely what you are experiencing. Phono is always louder
Your tables aren’t properly isolated. What do you have them on? What’s happening is the bass is causing your table/stand to vibrate and that vibration is picked up by the needles causing a feedback loop. You need to better isolate the tables from the stands. If that makes sense.
My turntables are on a wooden table that has a drawer inside (hollow) and my subwoofer is underneath it. That’s probably what it is 
i assume they’re grounded properly?
what do you mean by grounded?
The ground wire off of the turntables… Make their connection to the mixer is good.
Ha I didn’t read the original post right… Vibrations can give you that trouble like dude said above…
You should place your sub in corner of room and you should be ok
