1. An audio system, comprising:
an audio device; and
a control device operationally connected to the audio device and configured to set a frequency of the audio device to a first radio frequency corresponding to a selected radio broadcast and receive a first broadcast signal,
wherein the control device is configured to:
receive a second broadcast signal for an alternative frequency associated with the first broadcast signal with receive sensitivity of predetermined first reference sensitivity or more than the predetermined first reference sensitivity while the first broadcast signal is received through the audio device and verify and store a second radio frequency for transmitting a same broadcast as a radio broadcast of the first radio frequency based on a comparison between the first broadcast signal and the second broadcast signal;
receive a third broadcast signal for the alternative frequency, in response that the first broadcast signal with receive sensitivity less than the predetermined first reference sensitivity, but greater than or equal to predetermined second reference sensitivity is received, and change the frequency of the audio device from the first radio frequency to a third radio frequency corresponding to the alternative frequency based on a comparison between the first broadcast signal and the third broadcast signal; and
change the frequency of the audio device based on the second radio frequency, in response that the first broadcast signal with receive sensitivity less than the predetermined second reference sensitivity is received.
