Module A-115 (DIVIDER) is a four-way frequency divider. The frequency of a signal at the input is halved (half frequency = first sub-octave), quartered (1/4 frequency = second sub-octave), and so on. In this way, the DIVIDER produces four sub-octaves (F/2 down to F/16). At the output, the A-115 produces a summed mix of the original and the four sub-octaves. There are attenuators to control the amount (ie. Amplitude) of the original signal and each of the sub-octaves. Bear in mind that the sub-octaves output by the A-115 are all true square waves. If you put, eg., a sawtooth into the Divider, it changes it into a square wave before the frequency division takes place (using the SchmittTrigger system, if you’re interested). At the output, therefore, there are always four square waves and the original signal available.
