The artists require to know the technical specifications of the projectors/LED walls (or both) in terms of resolution, input cable and layout of the various outputs (in the case where more than one is present).
Audio-wise the artists' only need is stereo speakers/mixer input.
Failing to specify these criterias can result in longer times to setup everything in time and correctly.
