Despite a manual in English it is very simple to use this filter because all functions are easily identifiable. A big advantage is that is frquence interrieure Determines the device, it prevents the wandering hands of the go or they can not. The rev limiter is ffective and we just choose to use or not and with adjustable threshold.

An amazing quality not even a single breath on four tracks of "super acute" and is heard no movement when the signal limiter into action.

The unit I possde in 1992 and is always on top with its always good, no sign of weakness.
Again if it was our era, I would opt more for a type BSS MODEL numrique but will always remain a "rolls" of the filters
I advice those who do not have a budjet trs important because even if it cost the era equivalent of 800 one can find second-hand price is affordable and it all remains a sure value much better than some filters present
