X*]
This command sets a specific volume level for the audio output at either the display device or via an optional auxiliary Extron switcher. X*
= volume level (0 to 100). Default
volume = 25. When no switcher is detected at the MLS port, the maximum volume level is limited by the max. volume range command (
X?
*47#).
N
The MLC responds with an E14 (not valid for this configuration) error if you attempt to set a discrete volume level while
the MLC is in increment/decrement volume mode (volume mode 1). This command works only when the MLC is in volume mode 0. See the 46# volume knob mode SIS command.
