Viewing and Adjusting the Local Output Volume
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, 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) ” on page 59).
1. Press the Esc button to clear any input buttons, output buttons, or control buttons that
may be lit.
2. To enter Audio mode, press and hold the Audio button until the button begins to blink
red, then release the button.
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 ”, 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.
NOTES: • Only the volume for the local audio outputs (outputs 1 through 4 [matrix
sizes 816, 168, and 1616] or outputs 1 through 8 [matrix sizes 1632,
3216, and 3232]) is adjustable. Outputs outside the local range cannot
be selected in step 3.
• 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 Video 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.
