muP-controlled mixer board (1)
The audio mixer board presented in this article cannot be compared with any mixer board previously published in this magazine. In a way, it is the prelude in a new era in audio engineering. All controlls are operated by integrated digitally controlled amplifiers (DCAs). The position of the slide potentiometers is converted by a microprocessor into a control signal for the DCAs. It is even possible to do away with the potentiometers and microprocessor and leave the control of the mixer board to a PC, but this will be the subject of a future article.
