OPERATION NOTES

The UTC BA3308 has a built-in power-on mute circuit to prevent generation of a “pop” sound when the power is

applied. The generation of the “pop” sound is prevented by the DC blocking capacitors C3 and C4 connected to pins 1

and 9, and the charge time required for the ripple filter capacitor C8 that is connected to pin 6.

To ensure correct operation of this circuit, use the values given in the application circuit for C3, C4, R3, R4, C8 and

R8.
