2 Dynamic cutterhead EQ compensation. Precision is your friend

In this video I show a practical method for linearising the frequency response of dynamic disc-cutting systems using iterative EQ compensation. The process combines: • cutterhead response analysis • RIAA encoding • repeated correction passes • playback measurement through a cartridge • broadband EQ compensation • real-world music verification The idea is simple: Instead of trying to force the system into perfection in one step, we allow it to reveal its behaviour gradually through repeated cuts, measurements and corrections. This workflow is aimed mainly at: • dynamic cutterheads without feedback coils • DIY and semi-professional cutting systems • lathe enthusiasts • experimental mastering engineers • anyone interested in the physics of disc recording Topics covered: • playback system setup • cartridge alignment • calibration to 7cm/s • diameter loss • pink noise analysis • EQ matching • iterative compensation • groove safety • wow & flutter considerations The examples in the video use TDR Nova, but similar EQ matching tools should work as well. ------------------------------------------------------------ DOWNLOAD FILES: https://mega.nz/file/6kQGhAJb#OSfxhrf... ------------------------------------------------------------ RELATED VIDEO: Setup for a Fixed Pitch System    • 1 Setup for a Fixed Pitch Sytem   ------------------------------------------------------------ Thank you for watching.
