Create an IFB using Dashboard 2. Dashboard will assign a mix resource at two locations (primary and secondary) 3. Add a source (mix minus from console) 4. Add a destination (IFB Transmitter) IFB 5. Destination will subscribe to primary MC address 6. Mix Minus is routed to primary IFB mix 7. Destination hears mix minus 8. Add IFB key to Intercom panel(s) 9. Panels can talk across IFB feed – mixer will ‘duck’ mix minus per configuration Example: What happens when I create an IFB? 239.123.456.7890 239.123.456.7890 I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 Thank you Thank you to our Media Partners Martin Dyster, The Telos Alliance martin.dyster@telosalliance.com +44(0)7900 584066 22 Dashboard Advanced Lectrosonics IFB TX Telos Analog xNode IFB IFB LAN
