Information On Muting Characteristics

The muting operation is performed by an AF mute amplifier, the gain of which decreases

with the increased gain control current applied to the pin 6. (The control current is supplied

by a muting drive circuit and change continuously the gain of an AF mute amplifier) But the

higher. The lower limit of the gain under this condition depends on a resistor connected

between the pin5 and the ground. And the more the resistance increases, the more the

gain decreases. Thus the maximum attenuation will be set by connecting the resistor

between the pin5 and the ground. Fig.1 shows the muting attenuation with different R

5

between the pin5 and the ground.
