What does sACN/Art-Net refer to in lighting systems?

sACN (Streaming Architecture for Control Networks) and Art-Net are protocols used for transmitting DMX512 lighting control data over Ethernet networks. These protocols are specifically designed to cater to the needs of lighting fixtures and control systems, allowing for a more extensive and flexible approach to managing stage lighting compared to traditional DMX cabling.

Utilizing Ethernet networks enables multiple fixtures to be addressed and controlled without the limitations that come with physical DMX cabling distances and connection limits. This capability is essential in modern stagecraft, where complex lighting setups are often managed via computer software, making sACN and Art-Net vital components for professionals in lighting design and stage production.

In contrast, the other options represent unrelated concepts in stagecraft and lighting systems. The type of lighting bulb refers to physical light sources, a type of stage light fixture denotes the specific hardware used to project light, and a system for sound amplification pertains to audio equipment rather than lighting control. Thus, understanding the function of sACN and Art-Net is crucial for anyone working with contemporary lighting systems in stagecraft.
