• HD output
Audio Insert: insertion of audio in the HD output signal may be set to Auto or OFF. When set to Auto,
only the audio groups containing at least one audio channel will be embedded at the output. When set
to OFF, no audio is embedded in the HD output.
• SD output
Audio Insert: insertion of audio in the SD output signal may be set to Auto 24 bit, Auto 20 bit or OFF.
When set to Auto, only audio groups containing at least one audio channel will be embedded at the

3.4.8 The Audio Out (AES) panel
This panel provides additional audio processing for
the 4 discrete AES outputs.
Operation Mode (Off, A, SUM(A+B), Mix): This
menu allows the source of each output channel to
be selected – a single channel, the sum of two
channels or a mix of two channels.
Off: The output channel is muted.
A: The output channel is the channel source
(ABUS Select and Channel) selected in sub-
menu SOURCE A.
SUM (A+B): The output channel is the sum of
the two channels sources (ABUS Select and
Channel) selected in sub-menus SOURCE A
and SOURCE B.
• If you select this option, the SUM (A+B)
Level pull-down is activated, allowing you to
reduce the level of the summed output
(0dB, -3dB or -6dB).
Mix: The output channel is a mono mix of the
(ABUS Select and Channel) selected in sub-menus SOURCE A and SOURCE B.
