What is the consequence of failing to match frequencies in audio equipment?

The consequence of failing to match frequencies in audio equipment primarily leads to no audio signal being transmitted or received. When the frequencies of transmitting and receiving equipment are not aligned, the devices cannot effectively communicate or process the audio signal. This lack of frequency matching creates a barrier preventing any sound from being heard, resulting in a total absence of audio output.

In contrast, while unclear audio recordings may occur due to various issues such as interference or distortion from mismatched settings, the immediate and most significant effect of frequency mismatch is the absence of a recognizable sound. Other consequences, like equipment overheating or malfunctioning permanently, are not directly related to frequency issues but could stem from other factors within the equipment's operational parameters.
