3.3 Volume

Figure 3-6 shows the default volume in PPC3 GUI.

Note: The volume must be specified in decibels (dB).

An independent volume change for the left and right channel can be achieved by deselecting the Gang option.

The volume block is implemented using an alpha filter structure. As Figure 3-7 shows, when a volume level change is initiated, the volume block provides a smooth transition to the newly commanded volume level without producing artifacts such as pops and clicks.
