Pearl Nano User Guide Add an audio source to a layout
l
The XLR L/R audio inputs and the RCA L/R audio inputs are linked within Pearl Nano. If you use both
at the same time, their audio is mixed. If the two audio sources share the same audio signals, the
common audio signals are amplified. To avoid this, you can disable one or the other audio port, see
Assign audio sources to an input .
l
If a channel is selected as the video source for a layout, the corresponding audio for that channel is
added automatically.
l
You can add multiple audio sources to the same layout. However, if the two audio sources share all
or some of the same audio signals, then the common audio signals are amplified.
l
Selecting multiple loud audio sources in the same layout may cause audio clipping on that layout.
Before going live, always check the volume levels for the layout and adjust the volumes at audio
sources to avoid clipping, see
Adjust audio gain and delay .
l
If audio encoding is not configured for a channel, no audio signal is processed or sent with the
video content when recording, streaming, or confidence monitoring, see
Configure audio encoding .
l
If an audio source is added to a layout and then the audio device is disconnected from the input
port on Pearl Nano, some residual noise may be detected in the layout. Remove the audio source
from the layout.
