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 [98 dB] attenuation). The audio level can be adjusted from the front panel or under RS-232/RS-422 control.

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 (>) and View (<) buttons to increase and decrease
	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.
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 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 LEDs to both RGBHV and Audio lit.

•Pressing the Enter or Preset button also exits Audio mode. Pressing the Preset button changes to Recall Preset mode.
