transmitted. Therefore, with a mono transmission, there is  
no audio output at pin 7. When the signal level at pin 15 is  
greater than typically 1.0 mV (RMS value) mute is  
switched off.  
Second sound carrier mute  
The output of the second FM demodulator is muted when  
the signal level (signal and/or noise) at pin 15 is less than  
typically 0.5 mV (RMS value). This avoids an incorrect  
stereo or dual sound identification when a mono signal is
