Hi folks:

A lot of the early compressor-limiters used a feedback design (that it, the cobntrol voltage was derived from signals picked off after the gain control element: the Teletronics LA-2 and LA3, the UA 1176, etc. Feedforward compressors, as I understand it, didn't start to arrive until the 1960s and 1970s.

Why? Is there something about feedback compressors that makes them easier to design when part costs are limited? And were other early comp-limitters like the Federal, RCA and Fairchild also feedback?

Peace,
Paul
