(6) Soft mute operation
The LV3328PM have a soft mute function for low switching noise, when this mute function set operation.
(mute/unmute function select)
The Soft mute time can be selected by send to I²C control. (0.6ms, 5ms, 40ms, 80ms)
A soft mute function can be implemented by set to soft mute on. (Set to mute on/off)

(7) Cautions for input switching (method to reduce the switching noise at a time of channel setting)
When switching the input channel, carry out soft muting beforehand. After completion of muting, carry out channel
switching. Then, cancel muting (canceling through soft muting ), and complete input switching (recommendation by
SANYO).
Note also that, regardless of whether each input channel is set to ON or OFF, the external input voltage is less than the
maximum input voltage (VCL) in all input channels.
