Monitoring audio and VU sensitivity

You can connect headphones to the 3.5 mm audio jack on the front panel of Pearl Nano and monitor audio for the channel. To monitor audio for the channel, make sure the Channel view is displaying on the front screen. The audio you hear depends on the channel's custom layout. That's because you can choose different audio sources on the custom layout. To monitor audio for a specific video source, make sure the screen for the video source is displaying on the front screen.

To adjust the headphone volume, use the up and down arrow keys on the control key interface when the Channel view or one of the video sources is displayed on the front screen. See Monitoring audio for details.

A VU meter on the front screen shows the audio levels for the channel. The value is displayed in dBFS (decibels relative to full scale). Colored bars represent the audio level.

Audio VU meter levels

Color	Decibel range
Red	0 to -9 dBFS
Yellow	-9 to -18 dBFS
Green	-18 dBFS and lower

You can also monitor the audio VU meters for all audio inputs from the Audio inputs screen. If you don't see the Audio inputs screen displayed on the front screen, press the left arrow key on the control key interface to cycle through the different views.
