Viewing and adjusting the output volume
(systems with audio BMEs)
On MAV Plus audio BMEs, the audio level of each local output can be displayed
and adjusted through a range of 100% (no attenuation) to 0% (maximum [76 dB]
attenuation). The audio level can be adjusted from the front panel or under
serial port 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.
See “Setting the front panel Locks ( Executive modes)” on page 3-43.
1 . Press the Esc button to clear any front panel button indications that may be lit.
2 . To enter Audio mode, press and hold the Audio button until the button starts
blinking red, then release it.
3 . Press and release an output button to select an output. The input buttons
display the volume level for the selected output. As a general rule, the more
buttons that are lit, the higher the volume. The fewer buttons that are lit, the
lower the volume.
For a more detailed analysis of decoding the displayed value, see “Reading
the displayed volume (audio models)” on the next page.
4 . Press and release the Esc ( > ) and View ( < ) buttons to increase and decrease
the audio volume.
5 . Press and release the Audio button to save the audio settings and exit the
Audio mode. The Audio button stops blinking.
N • There is one audio volume level setting per local output. The audio level
setting is shared by the left and right audio inputs.
• The audio volume levels are stored in non-volatile memory. When power is
removed and restored, the audio level settings are retained.
• Exiting Audio mode by pressing the Audio button always returns the I/O
buttons to RGBHV (CrossPoint) or Video (MAV Plus) lit green and Audio
lit red.
• Pressing the Enter or Preset button also exits Audio mode. Pressing the
Preset button changes to Recall Preset mode.
