I never saw a Cedar  unit in any radio station i was associated with, however  almost every audio rack in master control had a "Dynafex" processor in the studio chain.
Great unit that provided a variable hi frequency band with based on apmpltude and hi frequency content. 
The quietier the  content the hi frequecies were reduced thus masking surface noise or  tape hiss.  The unit also had an aural exciter to preserve the brilliance of the  remaining signal... this was user  adjustable from the front.
I still have one of these in my studio......
