Before I mixed Dialogue
In my 20's I used to DJ (who didn't circa 2001) Vinyl and Technics 1210s were my tools.
Looking back it has certainly helped me with dialogue mixing, being able to blend audio sources, timing and pace, slow and hard cuts.
I have retired my decks my but all of my mixes are online.
