SDAS: Source Select for Sound Effect (Tone Control, 3-D Sound, Notch Filter, Mono Mix)
Default value: 0
The PCM3793/94 includes sound effect circuits (tone control, 3-D sound, notch filter, mono mix) which can be
used to filter either the digital input to the DAC or the digital output from the ADC. This bit selects the signal
source of the sound effect circuit.
SDAS = 0
SDAS = 1
DAC digital input (default)
ADC digital output
3DEN: 3-D Sound Effect Enable
Default value: 0
This bit is used for enabling the 3-D sound effect filter. This filter has two independently controlled parameters.
3DEN = 0
3DEN = 1
Disable (default)
Enable
3FL0: Filter Selection for 3-D Sound
Default value: 0
This bit is used for selecting fron two kinds of filter type, narrow and wide. These filters have a different 3-D
effect performance.
3FL0 = 0
3FL0 = 1
Narrow (default)
Wide
3DP[3:0]: Efficiency for 3-D Sound Effects
Default value: 0000
These bits are used for adjusting the 3-D sound efficiency. Higher percentages have greater efficiency.
