About automatic channels Auto A and Auto B
To get you started as quickly as possible, Pearl-2 comes pre-configured with two channels: Auto A and Auto B.
Simply plug a source into one of the "A" inputs and a second source into one of the "B" inputs. Pearl-2
automatically configures the channel's frame size to match the source resolution and configures a frame rate
and bit rate. Audio, if present, is automatically added to the channel.
Default audio setup for the auto channels is always as follows:
Video Source Audio Source
SDI SDI Audio
HDMI (DVI) HDMI Audio (no audio for DVI)
USB video USB audio
