Appendix A: If This Is Your First Digital Console
A digital console's main function is also to combine and process multiple signals, but all of this work is done strictly
in the digital domain, meaning that analog input signals must first pass through analog-to-digital converters
(ADCs) and all analog output signals must first pass through digital-to-analog converters (DACs). (See Figure 2)
