Doepfer A-100 Basic-System 1, 19" (PSU3)


The BS1 is one of many exemplary systems which the manufacturer configured himself and offers at a special price. In this case the classic use of the modular system as an analogue synthesizer with typical or known sound forms is the main application. The fact that this system, thanks to modules like the trigger delay, already exceeds the possibility of hardwired comparable models by far, is self-understandable due to its great value components. We are happy to recommend a personal composition of a complete 6-unit framework for beginners. And we’re likewise happy to help with the enduring work of researching set ups.



23 modules in a 6U frame incl. power supply. Internal pitch CV and gate bus. The system comes with 30 patch cables (mixed).
