The URS A series is a Class AB classic in every sense of the word. Each band offers 7 switchable filter frequencies spanning 4 to 5 octaves. The URS A series is unlike any other equalizer you will ever use.

Many EQ’s today offer a huge assortment of complex features, but the URS A series provides the engineer with just what is needed. The four bands overlap for track sweetening or specific problem solving. The low and high bands are selectable peak or shelving.
