One of TT's finding in Indiana was that they had no understanding of the structure's limits which made it challenging for event organizers to understand where the cut-off threshold needs to be in spite of any meteorology reports they may have been receiving. That's in no way any excuse, but it...

Ballasts were water tanks. Hard to know how many were there in total since they were tugged by the collapse and possibly cleared away as part of the rescue operation.Eye-balling it from other images, the video wall appears maybe >2x the size of the one at Sugarland, which is a considerable...

Appears there were a fair number of guy wires, but how adequate they were is impossible to know -- and all the guy wires in the world won't do much if that video wall is swinging in the wind like a sail. The direction of wind looks like it hit that video wall square on.

In the video below you can see it was steadily windy before the failure and the video wall was kicking forward before the collapse. Looks like there was a sudden violent gust that did the structure in.Toggling through the historical weather data, not only did this happen yesterday, but it...

In that case, I would strongly recommend performing due diligence on a hoist solution. Fewer structural implications and safer/easier to operate. Not having to schlep bricks around also makes it a little faster to do turnarounds if the space is being used as heavily as it sounds like it is...

"Substantial" may or may not be a big deal here. It really depends on the original structural design and the margins the original structural engineer designed into that structure.One of the primary benefits of lineshaft winches or compression tube hoists would be that you're minimizing the...

What's the existing rigging configuration in the MS?

Depends on the end pin and pad. Mass and contact area doesn’t factor in much when the energy tuning forks from the body of the instrument.Yeah. Maso/Hardboard is better than vinyl, but hardwood is better yet.Lot of factors though. Subfloor construction, sleeper spacing, if it’s a sprung...

There is no simple answer to this question.Generally -- a wood stage floor versus a vinyl dance floor on top of that wood stage floor will perform the same in terms of decay time within the room. They're both equally reflective in terms of airborne sound. Keyword -- airborne.However -- for...

Easiest way is probably doing RDP for a remote desktop from a mini PC with the capability to drive 3 monitors. Video quality may be a little degraded but most of the heavy lifting is still happening on the primary PC and just streaming video and control to your remote PC. This is probably the...

At some point it becomes more a hobby-into-retirement than a business.I know several guys that aren't comfortable going cold into retirement but keep their businesses alive on a low-flame -- not necessarily because it pays the bills anymore, but because it's a thing they do to pass the time...

Is this an official ETCP practice question? A question referencing "Source 4 Lekos" shouldn't be anywhere near an accredited exam.

Look for used D20 modules on eBay.As groups retire touring racks and do relay module swaps as they upgrade from tungsten to LED, there is a surplus of fair-condition D20's on the used market. The demand for D20's is only shrinking so as the used market is flooded with these modules, the prices...

ETC's Colorsource relays allow this function.
