Auxiliary (Analog) Input Level Control 

There are two independent ways to manage the overall auxiliary (analog) input gain: 

Gain Settings: 

• Gain settings refer to the "pre-gain" added by the Auxiliary (analog) Input codec 

• Gain settings are defined in dB 

• Gain settings range from 0.0 to 24.0dB in 3dB steps 

• Default gain is 0dB (i.e. unity gain) 

• Increasing gain will decrease input dynamic range 

Level Settings: 

• Level settings refer to the "digital" gain added by the internal DSP 

• Levels settings are defined in dB 

• Full level range [value] is from –100.0 to 12.0dB 

• Default level is 0.0 dB (i.e. unity gain) 

• minLevel default is –100.0dB 

• maxLevel default is 0.0dB 

• Trying to use set command to set the level outside of the minLevel and maxLevel commands will result in a bounds error from text processor 

• No attempt at setting or incrementing gain will go outside bounds of minLevel and maxLevel

If the input source is USB Audio, then the following commands will execute successfully, and the gain will be adjusted but will not take effect until the input source is changed to auxiliary input or auxiliary and USB mix mode. 

Get the auxiliary (analog) input gain 

AnalogInput get gain 

Gets the level of the auxiliary input gain setting. 

Example command: 

AnalogInput get gain 

Expected return: 

+OK "value":6.0 

Set the auxiliary (analog) input gain 

AnalogInput set gain [value] 

Sets the level of the auxiliary input gain using [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput set gain 3.0 

Expected return: 

+OK 

Get the auxiliary (analog) input level 

AnalogInput get level 

Gets the level of the auxiliary input. 

Example command: 

AnalogInput get level 

Expected return: 

+OK "value":-6.0 

Set the auxiliary (analog) input level 

AnalogInput set level [value] 

Sets the level of the auxiliary input using [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput set level –3.0 

Expected return: 

+OK 

Increment and decrement the auxiliary (analog) input level 

AnalogInput increment level [value] 

Increments or decrements the level of the auxiliary input by [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput increment level 1.0 

Expected return: 

+OK 

Example command: 

AnalogInput decrement level 1.0 

Expected return: 

+OK 

Get the auxiliary (analog) input minimum level 

AnalogInput get minLevel 

Gets the minLevel of the auxiliary input. 

Example command: 

AnalogInput get minLevel 

Expected return: 

+OK "value":-100.0 

Set the auxiliary (analog) input minimum level 

AnalogInput set minLevel [value] 

Sets the minLevel of the auxiliary input using [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput set minLevel –40.0 

Expected return: 

+OK 

Increment and decrement the auxiliary (analog) input minimum level 

AnalogInput increment minLevel [value] 

Increments or decrements the level of the auxiliary minInput by [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput increment minLevel 10.0 

Expected return: 

+OK 

Example command: 

AnalogInput decrement minLevel 10.0 

Expected return: 

+OK  

Get the auxiliary (analog) input maximum level 

AnalogInput get maxLevel 

Gets the maxLevel of the auxiliary input. 

Example command: 

AnalogInput get maxLevel 

Expected return: 

+OK "value":0.0  

Set the auxiliary (analog) input maximum level 

AnalogInput set maxLevel [value] 

Sets the maxLevel of the auxiliary input using [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

analogInput set maxLevel –6.0 

Expected return: 

+OK 

Increment and decrement the auxiliary (analog) input maximum level 

AnalogInput increment maxLevel [value]

Increments or decrements the level of the auxiliary maxInput by [value] - note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput increment maxLevel 10.0 

Expected return: 

+OK 

Example command: 

AnalogInput decrement maxLevel 10.0 

Expected return: 

+OK 

Get the auxiliary (analog) input mute state: 

Command: 

AnalogInput get mute 

Expected return: 

+OK "value":false 

Set the auxiliary (analog) input mute: 

AnalogInput set mute [true or false] 

Mutes or unmutes the auxiliary input, note that these changes only take apparent affect when in Auxiliary or Auxiliary and USB mode. 

Example command: 

AnalogInput set mute true 

Expected return: 

+OK 

Toggle the currently auxiliary (analog) input mute: 

AnalogInput toggle mute 

Toggles the mute state of the auxiliary input. 

Example command: 

AnalogInput toggle mute 

Expected return: 

+OK
