The modular system once developed by Robert "Bob" Moog went through a long production period between 1964 and 1981, including its development process. At that time, the new, electronic instrument was an avant-garde pioneering work that still had to be explained to the public, but ultimately found more and more interested parties.
The CP3A-M from Behringer is an audio mixer with four level-adjustable inputs. The outputs are dual and available with positive and negative amplitude; this allows a waveform to be reversed. The CP3A-M is functionally enhanced by two 1 to 3 multiples.
