Viewing and adjusting the input audio level (audio models)
On models with audio, the audio level of each input can be displayed and adjusted
through a range of -18 dB to +24 dB to ensure that there is no noticeable volume
difference among sources (figure 3-56). The audio level can be adjusted from the
front panel or under serial port or Ethernet control. The default audio level is 0 dB.
