Add an audio source to a layout
Using pixels
If you need to specify an exact amount in pixels (rather than percent) you can type a pixel value in any of
the positioning value squares followed by the characters px (e.g. 56px). You can mix and match pixels and
percents changing only the boxes you want to use pixel values. At any time you can switch back to
percents by typing a percent. See
Resize and position items using percents or pixels
for more information.
Add an audio source to a layout
You can add multiple audio sources to the layouts for a channel using the Admin panel. By default, audio
is enabled for the channel on the channel's encoding page.
Pearl-2 and Pearl Mini
- Each layout can have the same audio sources in them or you can choose
different audio sources. An audio source has the same gain no matter how may layouts the audio source
is added to, or if you've added just the one audio source or several audio sources to the same layout.
Important considerations
l
For SRT, RTSP input sources, there's no need to manually add the audio sources separately to your
channel. When the network stream is connected to your Pearl device as an input source, a
corresponding audio source is automatically added to the list of audio sources for your channels,
even if there is no audio in the stream.
l
The XLR-B audio inputs and the RCA audio inputs are linked within Pearl-2. 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
.
l
The Pearl Mini audio from the connected HDMI video sources (HDMI-A or HDMI-B) is automatically
selected as the audio source for the HDMI-A and HDMI-B channels on Pearl Mini by default.
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. This can happen
with Pearl-2 if two in-phase microphones are placed in close proximity to each other.
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
