Behringer CP35 Attenuators

The first System 55, 35 and 15 synth modules came out in the early 70s and tended to be extremely expensive. They were mainly all discrete transistor designs as op-amps at the time were very high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like Keith Emerson, Stevie Wonder, Tangerine Dream and so many more, giving us some of the greatest records we’ve ever heard. Modular synths were a landmark development in electronic music and today, it’s about to get better.

Enter the Behringer CP35 ATTENUATORS Module. An authentic reproduction of the circuitry from the “Modular 55, 35 and 15” Series used by the world’s most famous pop, rock and jazz musicians. Now, musicians can build their very own, unique, synthesizer that can fit in a standard Eurorack case for a very affordable price. Mix and match specific modules to create your personal, unique synth to complement the music you play or go all out and fill a room, from floor to ceiling, with modules that’ll fulfill any synth geek’s wildest dream.

The CP35 features 4 passive attenuators with linked inputs and 4 separate outputs. Each attenuator knob can be used to adjust the level of the input signal passively from - ∞ to unity gain. Connecting a single signal to the first input will allow it to pass to all 4 outputs to have up to 4 variations of a single signal source. Introducing a signal into the subsequent outputs will break the chain from the previous input. For example, if you have a signal in input 2, then this will feed into input 3 and 4 leaving input 1 to feed out of output 1. Having multiple inputs allows you to attenuate 4 separate signals and be more flexible with your tone.

Along with the standard outputs, the CP35 also features 6-volt outputs. These outputs give a reference voltage of -6 Volts out of one pair and +6 Volts out the other. Also included are two banks of 4-point multiple circuits for you to be able to route multiple copies of input signals to other modules. The CP35 can be a powerful addition to your synthesizer rig by allowing you to have multiple sources output to multiple modules so you can shape and sculpt sounds that are sure to blow everyone away!

Installing the CP35 is simple as it was designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and screw in the module using the included screws. This allows for the CP35 to be mixed with other synth modules for a truly unique set up.
