Anti-Radiation-Filter

An Anti-Radiation-Filter is implemented to suppress the radiation at the SC-clock-frequency and its har-

monics. This radiation is only present if the stereo decoder is selected and/or SC-Filters are active

(<>0dB). If not, the filter can be switched off in order to optimize the noise-performance.

Speaker Attenuator

The speaker-attenuators have exactly the same control range like the Volume-stage. Every stereo speak-

er stage has an implemented independently I2C controlled and Mute pin controlled SoftMute stage (see

section mute capability of AP).
