List of Levels is not a type of control link. It is simply a type of control available on some DRs (for example, the DR3), making it easy for you to use one DR to dynamically control the volume in one of several different locations.
You are designing the audio system for a very large restaurant that includes a large lounge area. The lounge includes many entertainment options for its patrons—big screen sports from a satellite TV feed, a variety of music channels fed into a powerful speaker setup, and, on occasion, live rock or acoustic music concerts. There are, therefore, many different sources requiring volume control. The restaurant owners want the lounge personnel to have easy control over the volume of each of these sources. On some evenings, one source is more important than the others. For example, during the NCAA March Madness, the TV sports take precedence.
A DR3 works nicely for this scenario. The end user turns the DR3 knob to highlight a level control in the list on the DR3 LCD. The end user then adjusts the volume knob, which changes the volume for the highlighted source.
For this procedure, we assume you have already configured your Processing Map for the different audio sources and that your map includes some form of Level control for each source. For the purpose of this example, we will use actual Level blocks, although the Level control could be in another type of processing block such as an Output or Mixer block.
In the Processing Map, locate the relevant Level blocks and open their properties dialog boxes by double-clicking each block.
tip: To avoid visual clutter and more easily track the changes in all relevant participants, it is helpful when testing to place the properties dialog boxes for a single link's participants in close proximity to one another.
