Doepfer A-115 Audio Divider
- Order number: 120090
- Depth: 40
Fourfold frequency divider for creating up to four suboctaves. Separate controls for the level of the original frequency, 1/2 frequency (1st sub octave), 1/4, 1/8 and 1/16. The output signals are symmetrical square waves.
The potentiometers determine the level of the original signal and the sub-octaves:
- Orig. = original frequency
- F/2 = half of the original frequency = 1st sub-octave
- F/4 = one quarter of the original frequency = 2nd sub-octave
- F/8 = one eighth of the original frequency = 3rd sub-octave
- F/16 = one sixteenth of the original frequency = 4th sub-octave
From version "V2 2008" on on the PCB's top a jumper is available (JP3/Source #1) which determines if the ORIG control uses the original input (i.e. the unchanged input signal of the In socket, not converted into rectangle) or the rectangle signal (derived from the input signal) is used for the Orig. control.
In left position of the jumper (towards the front panel) the unchanged original signal is used. In the right position the derived rectangle is used.

A-115 @Doepfer
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
