I am the AV Director for a church. We just purchased 3 Sony DXC-D30 cameras from a local TV station that upgraded cameras.
The 3 DXC-D30's came with CCU-M5 camera control units with 165 foot 26 pin cables, and beyerdynamic DT-108 headsets with 3.5mm cables that connect to the cameras' intercom connector.
My question is the intercom. We need the ability to communicate with the camera operators running the cameras in the sanctuary back in the control room. I know these cameras have internal intercom systems that run between the camera and the CCU's. Is there a way to "daisy chain" all three CCU's together so all three camera operators can communicate with each other and the director back in the control room that is wearing a headset connected to one of the 3 CCU's?
