11  Tables of Hex Codes for Audio Input/Output Gain Control 

Sections 11.1 and 11.2 contain the tables of hex codes for input and output 

signal gain control adjustment, respectively. 

11.1 

Tables of Hex Codes for Audio Input Gain Control 

Before adjusting the audio inputs gain, instruction 42, the AUDIO 

PARAMETER SETTINGS FOR INSTRUCTIONS 22, 24, 25 is sent

This command is sent once, and the “ audio inputs gain adjustment”  mode 

continues until instruction 42 changes to the “ audio outputs gain adjustment”  

mode. 
Table 8 lists the Hex values for the audio gain control of the 5 inputs.
