What is an important consideration for audio management at a face-to-face venue?

A central sound board is a critical element for managing audio at a face-to-face venue because it allows for effective control and distribution of sound throughout the space. This centralized system enables the audio technician to adjust sound levels, equalization, and various inputs from microphones and other sound sources, ensuring that the audio is clear and consistent for all attendees. With a central sound board, the event can accommodate different types of audio requirements, such as speakers, presentations, and video content.

Other options, while they may have their merits in specific contexts, do not provide the comprehensive audio management that a central sound board does. For example, a portable microphone can be useful for specific situations or speakers but lacks the capacity to manage an entire audio environment effectively. Streamed audio only may be relevant for digital events but does not address the needs of an in-person setting where live sound is essential. Finally, designating 'no audio needed' dismisses the importance of sound in enhancing the attendee experience and conveying crucial information during an event.
