be patience to the heavy load.
Famous “Fairchild’s Conax model 602” first high freq instantaneous limiter.
Originally designed for studio applications
but most for LP’s disk cutting head. Immediately broadcasting engineers place it
successfully at on air audio processing side chain just to avoid over modulations due the
pre-emphasis works. Thus the “Conax” became the “father” of stereo pre-emphasis
limiter for broadcasting application. Incorporate with 2band super fast attack &
release times’ pre-emphasis limiter with clipping and high-pass filtering.
“Conax” is still effectively for HF limit applications on many today's studio
productions together with reference units from the past like Gates or Collins as May you
see on following photos.
