4.3.9 Audio Levels

Setup (System) > Inputs > Audio Levels

Figure 79. Audio Levels

The Audio Levels screen is used for these functions:

 Set the levels. You can turn on the pink noise on any single channel to check and adjust the

level. This assumes that you have a SPL meter. The adjustment is usually made when the

Master Volume control is set to -15.0dB.

 Check channel phase. This is done by enabling the pink noise on more than one channel

and checking the difference in sound level with an SPL meter or RTA.

 General testing or troubleshooting. The installer may diagnose a problem by muting

selected channels while playing content, or playing pink noise on selected channels.

 Setting digital volume level.

Note: The lighter blue areas contain settings that are saved in the configuration file. The

darker areas contain settings that are not saved.

At the top right of the screen, the current Input and current Output preset are displayed.

 Pink Noise – Select to turn pink noise on for a selected channel (1-16). Pink noise is

cleared when exiting the screen.

When operating with Pink Noise Multi Chan selected you can enable pink noise on

multiple channels.

When operating with Pink Noise Multi Chan unselected, only one channel may be selected

for pink noise, and any previous selection is cleared. Also, the analog level button for the

pink noise channel is automatically selected to simplify adjusting the gain after selecting

the pink noise.

 Analog Level for channels 1-16 – This affects only the analog output signal, not the digital

output. The value is the same as that shown in the EQ screen. Range is from -20dB to

+10dB in .5 dB increments. To change, first select the control, then use the front panel

adjustment knob to adjust up or down.
