about setting gain structure
There are two approaches the system designer can take in setting up gain structure
depending upon where output volume is controlled. The output volume of the DMP 128 is
controlled by either of the following two gain blocks:
•
Volume (e)
•
Pre-mixer gain (b)
notE: While the pre-mixer gain control is not in the output signal chain, it can
be used to control program level independent of mix-point levels.
In the following instructions, setup is described for output volume or pre-mixer gain when
appropriate.
