This is a very basic review of the processes of recording, tracking and mixing fully analog. From recording to a 2" tape 24 track, analog recorder, mixing on an analog mixing console through analog outboard gear to a 2 track 1/4" mastering deck.
Ampex ATR-124, the ultimate analog multitrack tape machine. This particular machine was used for Sesame Street in the 80's. It has been meticulously restored and performs even better than the impressive original specs. This machine is FOR SALE on ebay.
