support passing NOM information. Enable

NOM

if you want to place this output in

a constant gain mode. Default is on. When enabled, the NOM button light

illuminates green.

Gain

The Gain slider on the selected output in the Outputs 1–12 window is used to adjust

output gain level.

• Use the Gain slider to adjust output volume level.

You can also enter the level

directly in the 0.0dB box. If you select any level below -60dB, the signal will be

muted. The

Level

meter, when enabled, shows the signal level when a signal is

present.

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 output gain structure

How you adjust an output’s gain directly affects sound quality. The optimal output

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 output level properly, place a signal on the output at the

maximum level it will generate. Adjust the output gain until the peak level of the

input, as shown on the Level 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 signal-to-noise ratio without clipping

the signal.
