SET DISCRETE PREMIX ATTENUATION
Command code: 0x58
Description: command used to set the system premix attenuation to a specified value
Input parameters –
Parameter 1 - 8-bit channel number, 0 = all channels, 1...8 is single channel
Parameter 2 - 8-bit integer value for desired attenuation, 0…100
Sending a value of 100 will set the attenuation to -100dB.
