Module A-115 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. 

At the output there are always four square waves and the original signal available.
