Portable PA system in ITE
I was at ITE Ang Mo Kio this afternoon and I came across this setup there. That is a huge flightcase with amplifiers, processors and a mixer mounted in it. Apparently, what these guys do is to wheel out this flightase and connect it via Speakons to a patch panel, which in turn is connected to some permanently mounted speakers above the venue. So, in a way, this is is a portable PA system. The amplifiers and electronics are stored in here and wheeled out and connected up when there is an event and after the event, you close up the flightcase after unplugging the Speakons and the 16A power cable. This is a very good idea and it helps to protect the electronic items from what is clearly an outdoor venue.
