I've just had a meeting with the various contractors for this project.

Turns out they had an expert on board, but they did not really know what

we, specifically, were looking for (I got brought into this process late).

Guy works for a company called "Syracuse Time & Alarm". As in time punch

clocks, fire alarms and security systems. Who knew they did AV stuff?

Nobody in this town did, apparently, except this general contractor.

Anyway this guy assured me that they can do a wireless system encompassing

video and audio, in which the only wireless connectivity involves the

actual video and audio signals. They can supply spitter switches to enable

ganging two or more projectors to one source, but each projector will

operate on its own wireless frequency so we can have three presentations

running at once. They can supply a channeled audio system that will allow

separate audio for each room but allow them to be ganged together when the

moveable walls are down. This will also accommodate an RF assistive

listening system that will work separately in each room (and when the walls

are down, the same audio gets sent to the three separate systems).

The wireless will work off a USB stick plugged into the laptop. It doesn't

require any installation of software. But I don't know if this is

OS-agnostic. We use Windows here, and it didn't occur to me to ask about

Macs. We want people to be able to bring in their own laptops and some of

those may be Macs. It's a good question. I will pass it on.

The only other unanswered question for me is, can their equipment

accommodate the option of plugging a USB stick into the projector remote to

allow for PowerPoint presentations without a laptop? They are looking into

it; the guy did not know that such remotes exist.

Thanks, Ted.
