Viewing and Adjusting the Analog Output Volume
The level of each analog audio 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, USB port, or Ethernet control. The default
volume is 100% (no attenuation).
NOTE:
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)

3.
Press and release an output button to select an output that has analog audio. 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” below.

•
Only the volume for the analog audio outputs is adjustable.

There is one audio volume level setting per analog 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

Reading the displayed volume
This section is a detailed look at reading the output volume display on the front panel. If you
do not need to read the exact value of the volume setting, skip this section.
There are 65 steps of volume attenuation, with 1 dB per step (button push), except for 0-to-1,
which is 13 dB. At maximum attenuation, no input buttons are lit, 76 dB of attenuation is
applied, and the audio output is effectively muted. At no attenuation, all input buttons are lit
and the output volume is equal to the input signal plus any gain or attenuation that is applied
to that specific input using the input audio level adjustment (see
on page 48). Other than the minimum and maximum volume, the
matrix switchers indicate the volume differently, depending on the model (see the
page 56 to read the volume display for each display scheme).
