with FLEXSOUND Technology
The IC’s speaker amplifiers accept input from the stereo DAC and the line inputs. Configure the mixer to mix any combina-
tion of the available sources. When more than one signal is selected, the mixed signal is attenuated by 6dB for 2 signals,
9.5dB for 3 signals, or 12dB for four signals.
