The input LEDs display the selected output's audio volume level.
In this example, the lit input buttons indicate 40 to 41.5 percent of the applied audio

Figure 3-52 shows the same volume (41.5%) as in figure 3-51, but displayed on
a 16-output-button switcher, such as a CrossPoint 300 816 HVA.
In this example, the input buttons display an audio gain level of –39 dB.
