The modular system once developed by Robert "Bob" Moog, including its development process, went through a long production period between 1964 and 1981. At that time, the novel, electronic instrument was an avant-garde pioneering work that still had to be explained to the public; but eventually found more and more interested parties. Behringer has transferred the generously dimensioned dimensions to the compact Eurorack format and paid close attention to the fact that sound and function are in no way inferior to the cult object.

The CP35 Attenuators from Behringer is a quad attenuator for control voltages and audio signals with normalized inputs. Due to the normalization, one input is routed to the subsequent outputs, thus you can distribute up to four targets with different intensities from one source. In addition, all inputs are output mixed on the summing outputs (+/- 6V). Functionally the module is completed by two independently usable 1 on 3 multiples.
