CS3308 Controls Tab
The CS3308 Controls tab provides a high-level intuitive interface to many of the configuration options of the
CS3308. Control over the state of the CS3308’s MUTE and RESET input pins is also provided.
The Master X Mask check boxes are used to map each channel to the master controls. These check-boxes
reflect the state of their associated Master X Mask bits; when checked, the channel is un-masked.
The sliders facilitate control over the Ch X Volume registers, providing gain and attenuation in ½ dB steps.
The +¼ dB Gain check boxes are used to add an additional ¼ dB of gain to the volume level displayed for
each channel.
See the CS3308 datasheet for complete internal register descriptions.
