Codec Analog Output Volume Tab
The “Codec Analog Output Volume” tab provides high-level control of the CS42L56 class H output amplifier,
HP/Line output volume levels, charge pump frequency, DAC channel limiter, and overall master volume lev-
el. A description of each control group is outlined below.
Class H Controls
- Controls for defining the digital and analog advisory volume, charge pump frequency,
and adaptive power supply mode for the class H control to determine the appropriate power supply for the
HP/Line amplifiers.
Headphone/Line Amplifiers
- Controls for configuring mutes and for setting the volume of the signal from the
headphone/line amplifier and controls for the HP/Line mux.
Limiter
- Configuration settings for the peak detect and limiter in the CS42L56.
Master Volume Control
- Sets the volume of the signal out of the DSP.
Update -
Reads all registers in the CS42L56 and reflects the current values in the GUI.
Reset
- Resets the CS42L56.
