Reference Levels
NDI Sources can sometimes be too loud for an SDI environment. As such,
Reference level can be used to attenuate (reduce) the audio level for a particular
Channel/Group. For example, choosing the value "20" will attenuate the audio for
that channel/group by 20dBu.
Setting Reference Levels
To set the reference level, click the Audio Reference Level drop-down control and
select 0, 6, 10 or 20.

Audio Channel Number Default
8 audio channels is the BRIDGE NDI 3G system default. This can be changed to
either 16 channels or two channels depending on your workflow.
NOTE: Some NDI receivers (hardware or software) have problems when receiving 16
audio channels. To avoid this, use 8 channels or 2 channels as your system preset.

As you configure your BRIDGE NDI 3G device, consider how each Bank will be
used, i.e., as individual HD Channels, 4K/UltraHD Groups, Video + Key Groups, or
some combination thereof.
