Viewing and adjusting the output volume
The audio level of each output can be displayed and adjusted through a range of
100% (no attenuation) to 0% (maximum [85 dB] attenuation). The audio level can
be adjusted from the front panel or under RS-232/RS-422 or Ethernet control. The
default volume is 100% (no attenuation).
N Output volume is protected when front panel Lock mode 2 is selected. You can
view the volume in Lock mode 2 but you cannot adjust it from the front panel.
