Doepfer A-100 Basic System 2, 19" (PSU3)

The A-100 Basic System 2 contains all the components of BS1, but provides the Midi interface for those who want to integrate the synth into their MIDI setup. MIDI to CV/Gate connections are sent via an internal bus to the corresponding receivers (A-110 VCOs and A-140 ADSRs) unless connections with patch cords are made.

Nevertheless, prior to buying a per-configured basic system we´d rather give you a personal advice regarding your synth setup.

22 Modules in 6U 19" frame. Includes a power supply with 1200mA power. The note CV and the gate from the MIDI/CV interface are internally sent to the oscillators and the envelope generators via the CV/gate buss. 30 patch cords in mixed lengths are included.

The basic system 2 contains following modules:

• 2x A-110 standard oscillator
• A-114 ring modulator
• A-115 audio divider for creating up to four sub-octaves
• A-116 waveform processor
• A-118 noise and random generator
• A-120 24dB/octave Moog low pass filter
• A-106-6 XP filter, inspired by oberheim Xpander
• A-130 VCA with linear curve, for processing CVs
• A-131 VCA with exponential curve, for processing audio
• A-138a mixer with linear curve, for processing CVs
• A-138b mixer with exponential curve, for processing audio
• 2x A-140 ADSR type envelope with retrigger and inverted outputs
• A-145 standard LFO
• A-146 LFO with variable wave shapes
• A-148 sample & hold generator
• A-160 clock divider for dividing the frequency of a clock
• A-161 clock sequencer, an expander for the A-160
• A-170 slew limiter, for portamentos etc.
• A-180 multiples, a passive signal splitter
• A-190-1 MIDI/CV interface. Emits note CV, gate, and clock

The frame has a a strong power supply and two busboards, each with 14 module connectors.
The power supply provides you with:

• +12 V: 2 A
• +5 V: 4 A
• -12 V: 1.2 A
