AV Discipline: Show Operation

AV Jargon: InterCom, Comms, Head Set


A Talk Back system is a communication network that is used by Show Operators to share vital aspects of an event, ensuring all actions are performed in unison. With Show Operators positioned throughout a function space, you will find them wearing a headset allowing them to listen to the show call and contribute to the flow of information. Go video #3! Stage lights up! Microphone #2 up! These are all examples of the talk back communication.

The system comprises of any number of headsets and belt packs, which are allocated to each Show Operator including but not limited to camera, sound and lighting operators. At the heart of the system is the base station, which is typically located at the Control Desk for a central point of access.

The Talk Back system is capable of distributing multiple channels which allows for isolated communications. By allocating different channels, this helps to keep the information flow focused and relevant for the Show Operators. For example the audio operator does not need to hear the call for the Camera Operator to pull focus and change their shot.
