Audio Amplifier
Figure 20
Audio from the SSB is fed to the Audio Amplifier on the LSB. Left Channel Audio is fed to Pin 2 of 7702 while
Right Channel Audio is fed to Pin 5. Audio is output to the speakers on Pins 12 and 7. Left and Right outputs
are also fed to the Surround Sound Speaker Jack. The output of the Surround Jacks is the difference between
the Left and Right Channels. The Amplifier is powered by a 27-volt supply, which is present, as soon as power
is applied to the set. When the set is in the Stand By mode, a High on the Stand By line turns transistors 7710
and 7704 On placing a Low on Pins 11 and 3 of 7702. This turns the output stage of 7702 Off during Stand By.
When the User selects the Mute function, the SOUND-ENABLE line goes Low, turning transistor 7701 Off. Pin
8 of 7702 will go High, muting drive to the output stage. When Sound is present, the SOUND-ENABLE line is
High. When Power is removed from the set, the POWER-DOWN line goes Low, turning transistor 7711 On,
causing the SOUND-ENABLE line to go Low. This action mutes the audio output during Power Down to prevent
a POP in the speakers.
