Passthrough Input Channel Mapping
Selects one or sums/mixes the analog input signal into the passthrough Amplifier. Each bit of the
PASSx_SEL[4:1] word corresponds to individual channels (i.e. PASSx_SEL1 selects AIN1x,
PASSx_SEL2 selects AIN2x, etc.).
Ch. x Analog Soft Ramp
Configures an incremental volume ramp from the current level to the new level at the specified rate.
Ch. x Analog Zero Cross
Configures when the signal level changes occur for the analog volume controls.
Note:
timeout period of 1024 sample periods (approximately 10.7 ms at 48 kHz sample rate).
Passthrough Channel B=A Gang Control
Configures independent or ganged control of the passthrough channel settings. Mute is not affected.
