To enhance audio and video signals

The purpose of a signal processor in an AV setup is to enhance audio and video signals, making option B the correct choice. Signal processors perform various tasks, including equalization, compression, and effects processing, which improve the quality and clarity of sound and image. By manipulating these signals, they ensure that the audio and video output is optimized for the specific environment and equipment being used. This enhancement leads to a more immersive and enjoyable experience for the audience by addressing issues such as frequency balancing and dynamic range.

Other functions, such as regulating power supply, routing signals, or providing backup power, do not fall under the main role of a signal processor. These tasks are handled by different components within the AV system, ensuring that the signal processor's focus remains on improving the fidelity of the audio and video signals.
