2. From the Channel menu, select a channel and click Encoding . The encoding configuration page opens.
3. In the Audio settings, ensure that Enable audio is checked to include audio in the channel.
4. From the Audio format drop down, select an audio codec (AAC, MP3, or PCM).
5. From the Audio channels drop down, choose mono or stereo (default).
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 XLR / RCA 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.)
6. From the Audio bitrate drop down, choose a birtrate. For guidance, see audio bitrates . For stereo
audio, we recommend 256 kbps or 320 kbps.
7. Click Apply .
Multi-encoding and channel as a source
Pearl-2 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
