    2019 Mac Pro — crazy or not?

    Four streams of what? What kind of software? What kind of source? I've had four "streams" of video running off my 15" 2016 MacBook Pro from ProPresenter (live video and multiple discrete outputs, plus operator display) with no problems. And nine "streams" of 1080p video using Qlab and two...

    Broadcasting Legality Questions

    You'll have to contact whoever the music is bought from, and see what they allow. More than likely, they'll all say no. Some may allow you to buy rights to broadcast it however.

    Mac ProPresenter to iPad for Visually Impaired

    The app is intended for a presenter to control the deck, and do so very quickly. It does not transmit high quality graphics.

    Fog machine spitting fluid

    When's the last time it was cleaned? We run around 50 fog machines and that fixes a surprising majority of the problems we have. Including things like this.

    Mac ProPresenter to iPad for Visually Impaired

    Airplay is going to be miserable. Any connect/disconnect of a display is going to cause the Mac to refresh its displays, regardless of Mac mini vs iMac or physical vs AirPlay. And ProPresenter doesn't always follow those changes while running well. I might take a look at some of the different...

    3 Phase vs. 220 V for running revolve drive

    If you're driving a three phase motor on a single phase VFD, you'll need to derate the drive - generally by about half. Long feeds to the drive aren't necessarily bad, although you'll want to make sure you have a local service disconnect at the VFD if the (very) remote panel is more than 50' or...

    Control System for misters and LX

    Without any idea of the skills or budget available, I might suggest looking into Weigl hardware and VenueMagic software. The solenoids for the valves will determine what kind of IO you need to have available. VenueMagic allows for controlling and sequencing the solenoids in the same environment...

    No more GrandMasters on ETC consoles

    Personally, I never have events where a blackout from a GM is ever really a good response. I'd much rather have a panic button on a magic sheet that triggered a controlled fade to a decent look on stage. And for ease of training or quick action, you could very easily use the contact closure...

    Are 3D printed props worth it?

    I would say yes, if you're going to go with high end printers and continue to use it. If it's this thing off in the corner that isn't used because no one really knows how to use it, or because it keeps breaking, then find a different cool new toy and continue the partnership with the science...

    Need a Powered 8" monitor

    Powered K8's are ridiculously nice sounding for the size. Except as a monitor they're obnoxious because they don't have a way to set them sideways at an angle.

    Mixing Amp Fan Directions

    If the rack has rear rails and an open front/back, putting the RMX in backwards (mounted on the rear rails) would be the easiest. Then the air flow is all the same direction, even if it looks a little silly.

    Burr shoots Hamilton, Audience Panics, Three Injured

    There's a comment about the AED triggering an alarm. I know that's a pretty standard feature, however I'd argue that in a large assembly space that's not a good thing. It also makes me think having a building wide paging system is far more important from a life safety standpoint. Especially...

    Egress Lighting

    https://nationalfireinc.com/inspection-testing/emergency-exit-light.html Section 5-9.1.2 gives you 10 seconds from power failure to when the alternative source should supply power to emergency lighting. I will say personally that it's unacceptable to continue to operate without a working...

    2 loading galleries - physics and safety Q

    That was my immediate interpretation. Simply where the unused weight was being stored, based on where it's more likely to be used.

    Shoutout to ETC Customer Service and Sensor Upgrade

    You seem to have a lot of issues with lightning. If you’re going to have a large expenditure, the racks powered down, and electricians involved, it might be a good opportunity to also install some kind of surge suppression system.
