The AUDIOARTS D-75 console utilizes line input modules with interchangeable daughter cards for Analog and Digital audio inputs. Each input has A and B channel inputs as well as integrated logic controls for that fader. All these functions are done with the use of DB-25 connections allowing logic and audio to ride on the same hardwire backbone. The console featured expandable mic inputs with an additional quad mic preamp card, a ‘Superphone’ module with 2 caller channels, a line preselect, and tape remote modules.
