4 - DISCAS Demystified w/ Chuck Espinoza (2 of 2)

AV with JB

If you’re a Pro AV Integrator still using the old 4:6:8 Rule for calculating screen sizes in your projects, this is for you. After hearing me complain on LinkedIn about trying to make sense of AVIXA’s “new” (as of 2016) DISCAS Standard, Chuck Espinoza offered to answer all my questions over a Zoom call. Since he’s a Sr. Trainer w/ AVIXA, I decided to hit “Record” and share this informal training with you. This is Part 2 of the 2 part call that ensued. Hope you find it useful.
