Behringer CP3A-M Mixer (Unknown)
A Eurorack-format analog mixer module reproducing the circuitry of classic Moog modular systems.
Overview
The Behringer CP3A-M is a Eurorack synthesizer module built as a reproduction of the mixer circuitry in the Moog Modular 55, 35, and 15 series. It is sold as part of the Behringer System 55. It is a 4-input analog mixer with separate controls per channel, and it has two sets of outputs, one positive and one negative in polarity. The signal path is all discrete, with no integrated circuits, which is how Behringer goes after the vintage sound of the original Moog hardware. There are also two 1-to-3 multiples for splitting signals.

Design
The signal path is all discrete, with no integrated circuits, just like the original Moog CP3A mixer from the 1970s modular systems. The CP3A-M is meant to give the same sonic character and gain structure. It models the right-hand side of the Moog CP3A, which has a gain of two.
Context
The CP3A-M belongs to the Behringer System 55, a modern recreation of Moog's vintage modular synthesizer systems. It is a utility mixer in the Eurorack format, meant to copy the function and sound of the mixers in the original Moog Modular 55, 35, and 15 series.
