We were asked to provide sound for the TEDx Sacramento Conference and we were very excited. This was the first time we used our new JBL VTX system. We brought in our JBL Rep, Keith Erickson to tune the system to this massive, 3 balcony venue with an overall height of 60'. The arc of the array had to be rather steep to reach the upper balcony and we used 4 JBL VRX speakers along the downstage edge as front fill. The 3 JBL G28 Subs were placed in a cardioid pattern to keep bass frequencies off the stage. The system ran perfectly and the sound was amazing in every seat.
