Introducing an appropriate amount of delay to the
Other types of delay to consider when establishing delay parameters are delays which occur naturally as a result of processing operations within the XAP 800. Propagation delay is an example. This delay is caused by operations such as the conversion of the signal between analog and digital formats.

Gain
Gain establishes the gain level for this channel. Select a level between
Min/Max limits
Use the yellow and blue upper and lower limit arrows on the Gain scale to create minimum and maximum gain level limits. These limits only apply when using relative gain commands; absolute gain commands can exceed the min and max limits. Min/Max limits apply to all serially connected control devices and prevent users from adjusting levels beyond the min/max levels, provided relative gain commands are used.
Optimizing process gain structure
How you adjust the processing gain directly affects sound quality. The optimal gain setting is one which is adjusted as high as possible above the noise floor without introducing clipping. Clipping can cause distortion which can damage amplifiers and loudspeakers.
To adjust the processing gain level properly, place a signal on the output at the maximum level it will generate. Adjust the gain until the peak level of the input, as shown on the Process meter, just begins to enter the red (clipping) zone, then reduce the gain slightly until peaks no longer climb into the red zone. This setting will ensure that the XAP 800 maximizes the
