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.
