Procedure

Changing volumes and gains via external control is usually done using the csv (Control Set Value) command.  Alternatively, the csp (Control Set Position) command can be used. 

Note

External Control Protocol (ECP) is used herein as the example; however, there are equivalent methods in Q-SYS Remote Control (QRC) as well.

 

It is possible to do direct volume up or volume down commands using css (Control Set String). The formatting is as follows:

css NameofControl ++  

##(for a default increase of 1 dB)
css NameofControl --  

##(for a default decrease of 1 dB) 
##For other values:

css NameofControl ++x
css NameofControl --x
css NameofControl +=x
css NameofControl -=x

## where x is the value in dB of the desired increase or decrease.
