Abstract:
1. An audio system that provides a plurality of speaker output signals to a plurality of loud speakers, the audio system comprising: a FM receiver that receives an input signal and demodulates the input signal to provide an audio output signal, and also provides a control signal indicative of the reception quality of the audio output signal; and a multichannel sound reproduction system that receives the audio output signal and the control signal, and provides the plurality of speaker output signals where the sound reproduction associated with the plurality of speaker output signals is set by the multichannel sound reproduction system as a function of the control signal, such that multichannel sound reproduction is provided when the control signal value is greater than a first threshold value, stereo reproduction is provided when the control signal value lies between the first threshold value and a second threshold value and pseudo-stereo reproduction is provided when the control signal value is less than the second threshold value, the first threshold value being greater than the second threshold value; where the multichannel sound reproduction system provides mono reproduction when the control signal value lies below a third threshold value, and the second threshold value being greater than the third threshold value.
