What is the typical symptom of a faulty RCA cable in an audio system installation?

A faulty RCA cable typically manifests as "No channel audio" in an audio system installation. This symptom can occur due to a complete break in the wiring within the cable or a poor connection, resulting in a loss of signal transmission. When the audio signal cannot pass through the RCA cable, the channels associated with that cable will not produce any sound, leading to silence in the output.

The scenario described points toward a total failure of signal transmission, which is why 'No channel audio' correctly characterizes a symptom of a defective RCA cable. It is essential for RCA cables to maintain proper connectivity to facilitate audio signal flow from the source device to the amplifier or speaker.

Other options do not describe the typical symptoms of a faulty RCA cable. For example, 'Intermittent audio output' often suggests a connection issue or a partially broken cable, where sound may come and go rather than being completely absent. Meanwhile, 'Static noise' could indicate ground loops, interference, or issues with the audio source itself rather than directly a fault with the RCA cable. 'Increased sound quality' contradicts the implications of a faulty cable since such a situation would not enhance audio quality, but rather degrade it.
