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 (-15 dB to +9 dB for MAV Plus 128 AV RCA) to
ensure that there is no noticeable volume difference among sources (figure 3-55).
The audio level can be adjusted from the front panel or under RS-232/RS-422 or
Ethernet control.
