The Level block controls the volume of an audio signal. The block includes a full-range level control from +12 dB to -88 dB. Provide end users with control over audio volume by linking a DR1 or DR3 Level control to the Gain control of the Level block. Limit the range of volume control by setting the Minimum and Maximum parameters. Selecting Off @ Min mutes the audio when the level control reaches the specified minimum value. A Mute switch in the Level block allows muting the audio without affecting the level control.
Use the Level block to control the volume of an audio signal.
