The “CS53L30-1 ADC” and “CS53L30-12 ADC” tabs contain the controls for the ADC settings, including notch filter enable,
high-pass filter configuration, noise gating, volume controls, and input type. The controls on the left correspond to ADC1,
and the controls on the right correspond to ADC2.
• Disable digital notch filter—Disables the digital notch filter (applies to both channels of the ADC).
• High-Pass Filter—Controls for the high-pass filter (applies to both channels of the ADC).
• Noise Gate—Controls for the noise gate.
• Channel volume controls—Controls for mic preamp gain, PGA volume, digital volume, +20 dB digital boost, and
signal inversion (Channel A and Channel B have independent controls).
• Input channel type—Configures the CS53L30 for either analog or digital inputs (applies to all input channels).
• Enable soft ramp on all digital volume changes—Enables an incremental ramp on all digital volume changes
(applies to all input channels).
• Refresh—Reads all registers in all devices and updates the values in the FlexGUI.
• Reset CS53L30-1—Sends a reset pulse to CS53L30 #1.
• Reset CS53L30-2—Sends a reset pulse to CS53L30 #2.
