What can negatively affect system performance?

In audio-visual systems, several factors can negatively affect overall performance, and the most comprehensive answer includes all of them, as options represent common issues faced in AV setups.

Signal distortion refers to any alteration in the audio or video signals from their original form, which can lead to a degradation in quality, making the output sound or look less than ideal. This could be caused by poor signal routing, interference, or inadequate equipment support.

Cable quality is another crucial element; low-quality cables can introduce noise and excessive attenuation, which can further degrade the signal. Properly shielded and high-quality cables are essential for maintaining fidelity in transmission, especially over longer distances.

Equipment malfunction is also a critical component that can impact performance. If any piece of AV equipment such as projectors, speakers, or mixers is malfunctioning or not set up correctly, it will directly affect how audio and video signals are processed and displayed.

By recognizing that each of these factors—signal distortion, cable quality, and equipment malfunction—can independently compromise system performance highlights the interconnectedness of these elements in maintaining optimal functionality in AV systems. Thus, the correct answer effectively reflects that all specified issues can collectively impair performance.
