In AV technology, what does the term "latency" refer to?

Latency refers to the delay between input and output signals. In the context of AV technology, this can manifest when a signal is transmitted through various devices and systems, such as microphones, mixers, amplifiers, and projectors. Any time a signal is processed, transmitted, or converted—from the moment an input device captures audio or video to the moment the output device presents it—there can be a measurable delay.

This delay can impact performance significantly, particularly in live sound environments, where timing is crucial for synchronization between sound sources and video displays. High latency can lead to noticeable discrepancies, affecting the overall experience of the audience, such as audio that does not sync with the video. Therefore, understanding and managing latency is crucial for AV professionals to ensure seamless and coherent experiences for users.

Other terms in the choices, like the speed of data transmission or signal quality, are related concepts but do not specifically define latency itself. Equipment setup time also is an unrelated aspect, focusing instead on the operational efficiency and preparation processes rather than the timing of signal transmission. Thus, defining latency strictly as the delay between input and output signals accurately captures its essence in AV technology.
