I assume every speakers play individual audio, if some of them are playing same audio, you may use audio DA. here one of the post talking about multi-channel audio, please have a look. http://forum.dataton.com/topic/114-watchout-5-and-successful-surroundmultichannel-audio-setup/page-2?do=findComment&comment=1414 you can use mentioned hardware to play up to 8 channels per display pc. hope this help.

I think you can connect the Artnet DMX (Kissbox) to the network switch

Thanks for the feedback, Peter & Leonard!

I use Kissbox for LED control. you may try the following suggestion: 1.use Kissbox Editor to monitor the output singal, make sure the universe set to correct setting, and receive correct signal 2. make sure you set LED channel and value are correc, for example, channel 1 is Red channel 2 is Green channel 3 is Blue channel 4 is Intensity if you turn on 1,2,3, but channel 4 is 0, the LED wont bright up. every LED have different setting, please check the manual. 3.you need "ONLINE" to see the output/effect.

after i google "gigabit lan speed" i found an interesting article "Gigabit Ethernet: Dude, Where's My Bandwidth?" http://www.tomshardware.com/reviews/gigabit-ethernet-bandwidth,2321.html please have a look! i think it explain very clear.

25-30mb per second for 1 computer? how do you find out this number? when you online, watchout will upload required files to all display PC at the same time. may be this is the reason share the "bandwidth"?

make/modify the mask in Photoshop. then use Refresh(CTRL+R) then Update(CTRL+D) in Watchout.
