Viewing and adjusting the output volume (HVA models)
On HVA models, the audio level of each input 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
control. The default is 100% (no attenuation).
Output volume is protected when front panel lock mode 2 is selected. You can
view the volume in lock mode 2 but not adjust it from the front panel.
1. Press the Esc button to clear any input LEDs, output LEDs, or control LEDs
that are lit.
2. To enter the Audio mode, press and hold the Audio button until the LED
begins to blink, then release the button.
3. Press and release an output button to select an output. The input LEDs
display the volume level for the selected output. The switchers indicate the
volume differently, depending on number of input LEDs, but as a general
rule, the more LEDs that are lit, the higher the volume. The fewer LEDs 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 (

the audio volume by 1 dB per each push of the button or press and hold the
button to change the level at a rate of 3 dB per second until the button is
released or the upper or lower limit is reached.

Audio mode. The Audio button stops blinking.

• Exiting Audio mode by pressing the Audio button always returns the I/O
LEDs to RGBHV and Audio lit.
