Pearl Mini User Guide Multi-encoding and channel as a source
Choose Mono to have left and right stereo channels combined so that when you listen to the
streamed or recorded audio, the same blended sound comes through both the left and right
channels.
If you have only one mono analog input, use the left jack and select mono encoding to have
the same sound come from both the left and right channels. (If stereo sound is chosen, the
sound will only come through on the left channel.

we recommend 256 kbps or 320 kbps.

Multi-encoding and channel as a source
Pearl Mini lets you easily do multi-encoding so you can record and stream the same content at different encoding
settings. This is useful when you want to:
l Record a video at a high bitrate and frame size and live stream the same content at lower encoding
settings.
l Record the channel while also sending two (or more) streams of that channel using different encoding
settings for CDNs that don't use adaptive bitrates.
l Or record the same channel simultaneously at different resolutions, like full HD and HD.
For example, take a scenario where you want to record a video at 1080p and 8 Mbps, while simultaneously live
stream the same video online 720p and 1 Mbps. You can create your custom layouts and do all your switching in
one channel (i.e. Channel 1) and then configure Channel 2 to use Channel 1 as a source. That way, both
channel's have the identical program. All you need to do now is configure each channel for the encoding settings
you want.
Follow these steps:
1. Login to the Admin panel as admin, see Connect to the Admin panel .
2. Create Channel 1 with your video and audio inputs. Add all your live switching layouts.
3. Set the encoding and streaming settings for channel 1.
4. Create Channel 2 for your recording with just one layout and add Channel 1 as the video source. Stretch it
to fill the full screen.
5. For Channel 2's audio source, choose Channel 1 if not already selected by default.
6. Set encoding and streaming settings for channel 2.
