Audio output volume

N• Individual controls, offering finer trim adjustments (in 0.1 dB increments) for the right and left channels and group master offsets are present in the DSP and available through software control (see “DSP Configurator Program”, in chapter 5, “Switcher Software“). The results of these controls are not shown in the responses below.

•The table below the commands defines the value of each audio volume step.

Set the audio volume to a					X@*X^V			OutX@•VolX^]
specific value
		Example:			1*50v			Out01•Vol50]				Set output 1 volume to 79%.
Increment volume					X@+V			OutX@•VolX^]				Increase volume by 1 step.
		Example:			1+V			Out01•Vol51]
Decrement volume					X@-V			OutX@•VolX^]				Decrease volume by 1 step.
