Input + C 10uF r r 1M This IC requires 0.1uF capacitor between INPUT and GND, 1M resistance between INPUT and GND for clamp type input at mute mode. Input C C 0.1uF r r 1M This IC requires 0.1uF capacitor between INPUT and GND for bias type input at mute mode. Input C C 0.1uF When the power supply voltage is not impressing, please do not impress voltage to the control terminal.
