Table 37.
The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital
zero-crossings no clicks will be audible.
Table 38.
The STA326 includes a soft volume algorithm that will step through the intermediate volume
values at a predetermined rate when a volume change occurs. By setting SVE = 0 this can
be bypassed and volume changes will jump from old to new value directly. This feature is
only available if individual channel volume bypass bit is set to 0.
