MUTE

When the mute pin is connected to the GND, all of outputs signal will be muted immediately.

Connecting the external R/C components on here could prevent the power–on “POP” noises, the mute

function also can be active by the external DC voltage.

Due to the built-in pull down resistor (150KΩ), a larger value series resistor connecting to the mute pin

may causes mute malfunction because of mute voltage divided by the resistor network. For the

detailed connection description please refer to the application circuit.

The attenuation of mute is relation with CB, we suggest CB must be higher then 10µF, the recommend

value is 47µF. Higher CB will have better mute characteristic.
