Mute Capability of Audio Processor
The main channel and the sub channel of the TDA7411 can be muted after the Source selectors. This
mute (no soft mute!) must be started by I2C bus.
The digitally controlled SoftMute stages are placed in the speaker and allow muting/demuting of the signal
with an I2C-bus programmable slope. The mute process can either be activated by the SoftMute pin or by
the I2C-bus. The slope is realized in a special S-shaped curve to mute slowly in the critical regions (see
Figure 3).
Figure 3. Soft mute-Timing
Note: Please notice that a started Mute-action is always terminated and could not be interrupted by a
change of the mute -signal.
Using the IIC bus control the soft mute can be activated independently for FrontL, FrontR, Rear and Free.
For timing purposes the Bit 3 of the I2C-bus output register is set to 1 as soon as the soft mute of any
speaker is started until the end of demuting of all speakers. The Mute pin is able to work as monitor for
the same signal. The standard function of the pin is not influenced by the monitor function.
