hi guys i m new to serato scratch live , before this i m a traditional vinyl and cdj user , recently i had purchased ttm57sl and 2 pcs of stanton t.92 usb equip with ortofon scratch , can anyone guide me to do perfect settings on the setup cause i cant really find any guide on the web . Here is the few problem i have .

1.) Serato Setup Screen show that i have heavy vibration on both my turntables , but it solved when i put both tt and mixer to phono but problem is not sensitive , if i put line on both it become super sensitive . I tried to calibrate by holding estimate , but no matter how i adjust the tone arm forever it goes to left side . Is it my turntable cant make it ?

2.) My Tunes tempo always up and down not stable compare to traditional vinyl .

Thanks for helping
