Audio gain and attenuation

The SIS commands for setting audio gain and attenuation are case sensitive. “G” sets gain and “g” sets attenuation. Increment, decrement, and view are not case sensitive.

Set gain

X12

G

Aud

X14

Set gain for the selected input to

 

 

 

dB.

 

 

X12

Example:

3G

Aud+03

Set gain for the selected input to

 

 

 

3 dB.

Set attenuation

X13

gAud

X14

Set attenuation for the selected

 

input to

 

dB.

 

X13

Example:

15g

Aud-15

Set attenuation for the selected

 

 

 

input to -15 dB.

Increment level

+G

Aud

X14

Increase the selected input’s

 

audio level by +1 dB.

Decrement level

-G

Aud

X14

Decrease the selected input’s

 

audio level by -1 dB.

View audio level

G

Aud

X14

View gain for the selected input.

Example

G

Aud-03

The IN1508 reports that the

 

 

 

 

audio level for the selected input

 

 

 

 

is at -3 dB of attenuation.

Audio output volume
