Default vintage 670 compressor

Can someone enlighten me as to which control sets the attack time on this compressor. The controls are not labeled with the standard control names. Thanks.

Did you mean Fairchild Model 670 Stereo Limiter?

Because it is not your standard compressor.

  4. 2 s
  5. 5 s
  6. automatic function of program material 2 s individual peaks, 10 s multiple peaks
  7. automatic function of program material .3 s individual peaks, 10 s multiple peaks, 25 s for high consistently program level
Also from the manual

Positions 5 and 6 combine fast release with slow release and can be useful if a great amount of automatic level correction is required. These positions also make the limiter action less audible since they will reduce overall program level if continual limiting persists.
