Which component helps to maintain signal integrity over long cable runs?

Line drivers play a crucial role in maintaining signal integrity over long cable runs by amplifying the signal and minimizing degradation that can occur due to distance. When an audio or video signal travels over a long distance, it may suffer from attenuation, which results in a weaker and potentially distorted signal reaching the receiving end.

Line drivers counteract this issue by boosting the signal strength, allowing for longer distances without compromising quality. They are specifically designed to provide a strong, clean output to ensure that the signal remains consistent and preserves fidelity, regardless of the length of the cable run involved.

While other components like matrix switchers, amplifiers, and peaking may serve different purposes in an AV setup, they do not directly address the need for signal integrity specifically over long distances with the same level of effectiveness as line drivers. Matrix switchers are primarily used for routing signals, amplifiers can enhance sound pressure, and peaking refers to adjusting frequency levels rather than directly addressing the integrity of the signal across long runs.
