The Portal provides a revolutionary metering display that allows for multiple
channels of metering on a single circular display. The Dolby Lake Processor provides
four Portals on the front panel, as shown in Figure 4-3.

Figure 4-3 shows a variety of Portal output-channel meter views, including four-way,
two-way, and three-way crossover modules, and a three-auxiliary-output module. As
this figure illustrates, each Portal represents all audio channels that are part of a given
processing module. Each custom LCD Portal display provides three ten-character
user-configurable text displays, two 104-segment rings, 16 mute and soft-function
buttons, arrow keys, and one
ME
button for Portal control and parameter adjustment.
