COMBINER
mixing of signals, audio-rate or control
Through extensive studies of various modules found in dig AG-105, we have realized that one of the most basic practices was the combination of signals together, what was called at the time “mixing”. Signals that produced audible outputs were mixed; signals that controlled other signals (“control voltages”) were mixed; in short, the mixing and combining of signals together was a constant need. Because of this, it’s no surprise that we would also find in this dig many examples of the aptly-named “COMBINER” module.
COMBINER is quite basic: there are three knobs at the top, three jacks for inputs, and one jack for an output. Input signals flow through the jacks, and the corresponding knobs would control the levels of the input signals. Based on these levels, the output would be a weighted sum of the inputs. Simple as that.
Such a module, however, required power to properly sum the signals together. While the summing could occur without power, power was needed to keep the sums at appropriate levels for further transport within the complete system.
These are the measurements we have for the COMBINER module, in the units of the time:
ARCHIVAL NOTE: As with all of the modules from “selestium modular” very little written text is found on the front of the modules; instead, custom iconography is present, the basics of which are found at the beginnings of each chapter in the selestium for the modules.
While the COMBINER module can combine both audible signals as well as control voltage signals together, it often does not make sense to combine an audible signal with a control voltage signal. It’s best to combine like signals with like, although nothing prevents you from mixing them up in specialised circumstances.
You can purchase COMBINER from the selestium vending website.
