I ran one for a while, worked great! I wanted to stream all 6 TTB Beacon shows last year from the loge rail
and i did it and a few others and gave it away to another taper. It was fun, the first night 100 users...the last night with Trey 1200
my standard rig line out/headphone out >sonicport > iphone 6 lightning port in. Sonic port comes with it's own lightning cable. (and 30 pin for older phones)
Mixlr iphone app to broadcast. I used a $20 month account, so i could stream on consecutive days with running into any time limit issues.
