Processing
For detailed information about the use of Dolby and DTS Neural options, see Advanced
Audio Processing on page 65.
The Input Audio Select parameter selects the audio source to be routed to all audio
outputs. This pre-empts individual audio controls. The default Map Through option routes
demux audio to mux and HDMI outputs, and AES audio to AES and analog outputs.
Figure 3-21 on page 52 shows the audio routing in the X50.
The AES Present, Analog Present , and DMX Channel Present read-only parameters
display the status of the incoming audio feeds. When you select these parameters, each of
the eight channels is displayed as a symbol.
The AES Present parameter has a unique feature that notifies you when an AES signal is
available for that channel (visible as a P symbol on the channel), but the channel has been
set to an analog input.
See Figure 3-20 on page 50 for an explanation of these symbols.
Note: The analog audio output of the X50 is always low-impedance. To ensure that you do
not overload the audio output, always connect to high impedance downstream.

Metadata
The audio metadata feature de-embeds audio metadata from various sources and then
re-embeds the audio metadata into multiple outputs.
The audio metadata source may be one of the following:

Metadata embedded in SDI (Methods A and B)

Input of the serial port

Metadata generator

AAP 1 Dolby E Decoder Output (when a Dolby E decoder is configured in AAP 1)

AAP 2 Dolby E Decoder Output (when a Dolby E decoder is configured in AAP 2)
