Hi Eric.
Till now I didn't use the nodes extensivly, in a large venue. The way I will use them will vary, I wanted an flexible solution to extend my universes, (locally) and also want to be able to use them on longer distances instead of using multiple dmx-lines on a long distance.
For both the way of configuring is very easy, the showtec can be configured on the node itself and via a browser, the lightshark only via browser. Both is very easy.
Both have external powersupply, Via adapter. showtec 12V and Lightshark usb 5.0 V . The Lightshark can be powered via PoE if you want, the showtec i'm not sure.
I tested both directly connected to the desk, and via a 19"switch. All worked well. I used the SaCN protocol.
My own projector-kit involves Clay Paky's and Elations,and some ADJ pro. (and dimmers of course, zero88, liteputer, and TTL) ) if I need to rent it is often CLF and Rogue.
I do not own or have used any Lyre Led till now.
So far for now, I will keep you informed if I notice anything of interest to share.
greetings! Ed
