Doepfer A-100BS3P6 Basic System 3 in P6 Case
The Doepfer A-100BS3P6 Basic System 3 is a complete 6U Eurorack modular synthesizer system built around a carefully selected collection of classic and modern A-100 modules. Designed as an accessible but highly capable platform for analog synthesis, it provides oscillators, filters, VCAs, envelopes, modulation sources, mixing, waveshaping, switching, clock processing, utilities, and signal routing in a portable A-100P6 suitcase.
Two A-110-1 Standard VCOs form the core sound-generation section, allowing conventional subtractive synthesis as well as detuned, synchronized, and more complex multi-oscillator patches. Sound-shaping options include the A-108 multi-slope low-pass filter, A-121-2 multimode filter, A-137-1 Wave Multiplier, and A-184-1 multifunction module with ring modulation, sample-and-hold, track-and-hold, and slew processing.
The modulation section combines the A-140 ADSR, A-140-2 Dual Mini ADSR, A-147-4 Dual VCLFO, and A-171-2 VC Slew Processor / Generator. Clock division and sequential switching are handled by the A-160-2 and A-151, while multiple mixers, VCAs, multiples, and utility modules provide flexible routing throughout the system.
The system is capable of classic monophonic synthesis, complex modulation patches, percussion and drum synthesis, self-oscillating filter sounds, waveshaping, and even multi-voice paraphonic configurations. Blank panels are included so additional modules can be added later without replacing the case.
All modules are installed in the portable A-100P6 suitcase, providing two 84 HP rows for a total of 168 HP. The case includes two bus boards and the A-100PSU3 power supply, delivering up to 2000 mA at +12V, 1200 mA at -12V, and 4000 mA at +5V. A removable cover allows the system to be transported while remaining a self-contained modular workstation. Doepfer
