Week 10: Signal Path
Creating the signal path when setting up a PA or lighting system can be a challenge. Consideration must be taken in to account for many different input sensitivities. The rated sensitivity can vary greatly between different manufacturer's for everything from DMX protocol to powered speaker systems and standard amplifier racks. And not all of them have volume or sensitivity adjustments. Modern systems require multiple outputs set at varying levels. It pays to have a clear understanding of these principles and have an ability to create a plan for your signal path that is flexible and redundant. In addition we will review specific diagramming techniques for documenting signal path and some of the conventions and rules that these documents follow. We originally examined some of these techniques in Chapter 7 of the SRH will review block diagrams and schematics as well.
