3U Modular

Modular Systems are a design approach that subdivide a 'system' into smaller parts called modules, that can be independently created and then used in different systems. A Modular System can be characterized by functional partitioning into discrete scalable, reusable modules; rigorous use of well-defined modular interfaces; and making use of industry standards for interfaces. Besides flexibility in design, modular systems offer other benefits such as augmentation (adding new solutions by merely plugging in new modules) and exclusion. 

Modular Synthesizers offer the user the musical equivalent to the Modular Systems. Modules such as VCO's LFO's and VCAs provide the building blocks used to build a Modular Synthesizer.

A given combination of, amongst many factors, physical dimensions, power supply voltages and inter-module connector types, are known as a format. There are currently 3 major size formats being 3U, 4U and 5U with each of these having various sub-formats.

EuroSynth-4 combines the power and flexibility of a true modular design with the patching power of 4mm banana jacks

4mm banana jacks offer a more robust patching system comprising a single solid 4mm 'pin' that has a much larger contact area than the standard 3.5mm (1/8") jacks, ensuring a longer-term reliable patch connections along with true stacking capabilities..
