Have you ever heard of Maryland Sound International? Well, they just pulled off what they think might be the “largest amplified event ever. Period.”
Pro Sound News covers the requirements for a presidential inauguration: JBL VerTec rigs hung on custom motorized portable poles dotted the National Mall. But the coolest thing (from a scientific perspective) is the time-delay required to make sure everyone hears the same thing:
Given the vast expanses needed to be covered, it took more than nine seconds for audio to travel from Obama’s microphone to the last loudspeaker, requiring that video fed to the many portable screens on hand be delayed to match the audio. Accordingly, MSI spent the last week working onsite, checking wires, listening to mixes and interacting with a government sound architect.
From what I can tell, everything went off without a hitch. Congratulations to MSI and all of their people for making a historic event sound great!
