The RS-280 is a divider module with a wide frequency range. It can be used to output either clocks with different divisors or sub-octaves of audio signals.
The module contains one signal input and five outputs.
The input accepts any signal within the voltage range of ±10V. The outputs carry square waves from 0-10V. The first one has the input signal´s original frequency, the others have the divisors 1/2, 1/4, 1/8 and 1/16. Each output has a LED showing the frequency; beyond 20Hz they seem to light constantly.
