“Audio Input Gain and Attenuation”: Request: <input>*<gain>G

Response: In<input> Aud=<dB Value><CR><LF>

Action: Sets audio gain to a positive value

Request: <input>*<gain>G

Response: In<input> Aud=<dB Value><CR><LF>

Action: Sets audio gain to a negative value

Request: <input>G

Response: In<input> Aud=<dB Value><CR><LF>

Action: Increments audio gain by 1dB

Request: <input>g

Response: In<input> Aud=<dB Value><CR><LF>

Action: Decrements audio gain by 1dB

The “Audio Input Gain and Attenuation” commands are used to adjust the audio gains on specified inputs. This command is specific to input adjustment, and cannot be used to adjust outputs. Examples:
