A-100

“In the A-100, Doepfer have produced a capable and versatile analog modular synthesizer, built in the style of the classic modular systems of the seventies. The renaissance of analog synthesis in the last few years shows that analog sound production has a vital place alongside sampling and digital synthesis, and can produce sounds that are unobtainable by any other means. In addition to the unique sounds of its oscillators, filters, amplifiers, phasers, frequency shifters, and so on, analog synthesis can provide almost unbounded modulation opportunities, conventional and unconventional – limited only by the number and variety of modules available.
In designing the A-100, our priorities were: good sound quality; diversity of modules available; ease of integration into a MIDI system; and, maybe most important of all, affordability.

A-108 VCF8 – 6/12/24/48 dB Lowpass

A-108 VCF8
6/12/24/48 dB Lowpass

“Module A-108 is a completely new voltage-controlled low pass pass filter based on the well-known transistor ladder (Moog ladder). The module has internally an 8 stage low pass filter with different slopes available: 6, 12, 18, 24, 30, 36, 42 and 48 dB per octave. In addition it features an band pass output (i.e. band pass with transistor ladder). In the factory the 4 low pass outputs of the A-108 are internally connected to the filter stages 6, 12, 24 and 48dB. From our first A-108 audio tests this seems to be the best output combination as these outputs generate audible different sounds. E.g. the audible difference between the 48dB and 42dB or between 42dB and 36dB is very little. But if desired any of the filter stages can be connected to one of the outputs.
