Xenon lamps have taken over from the carbon arc to give longer continuous film running times. Sound equipment has become more sophisticated since the introduction of Dolby sound systems.
Automation also plays a big part in the operation.
Today, preparing film programmes for this equipment, including 70mm, needs a great deal of care and attention for a smooth running operation with presentation to an acceptable standard that a modern audience demands. It is vital that staff responsible for operating and maintaining this equipment are properly trained. In most cases they work on their own and need to have the ability to solve technical problems quickly and efficiently. They are also responsible for all aspects of the cinema technical operation outside of the projection room, including lighting, heating and ventilation, fire alarms and equipment, electrical, water and gas supplies. They must also have a knowledge of the current local licensing requirements and Health and Safety legislation.
