What is a truss primarily used for in live events?

A truss is primarily utilized in live events to support and hang stage lighting, speakers, and other equipment. Its design allows for robust structural support, enabling it to safely carry the weight of heavy lighting fixtures and sound systems. By utilizing trusses, event organizers can efficiently position these elements above the stage or audience area, ensuring optimal visibility and sound distribution, which enhances the overall experience of the event. The use of trusses is crucial for achieving effective stage design and audio-visual presentation, contributing significantly to the production quality of live performances.

Other options mentioned do not align with the primary role of a truss. While equipment may need to be stored, that is not the primary function of a truss. Additionally, trusses do not create sound effects or provide power; they are structural components focused on support and safety in staging setups.
