whether group 1 will be output as AES1 and AES2 or embedded on the HD output. When DIP switch 1 is
set for HD embedded audio, DIP switches 2 and 3 are used to select which group on the HD output will be
used to embed the audio according to Table 10

DIP switch 4 on the bottom board controls whether group 2 will be output as AES3 and AES4 or
embedded on the HD output. When DIP switch 4 is set for HD embedded audio, DIP switches 5 and 6 are
used to select which group on the HD output will be used to embed the audio according to Table 11.

5.6. SELECTING IF AUDIO GROUP 2 IS ENABLED OR DISABLED (SET B)
DIP switch 7 on the bottom board allows the second audio group to be output or not (whether embedded
in HD or output as AES). When audio selection is manually controlled this switch should reflect the
encoders setting.

5.7. AUDIO OUTPUT AUTO/MANUAL SELECTION (SET B)
DIP switch 8 on the bottom board controls whether the destination for the embedded audio data is
determined automatically or by DIP switches 1 through 7 on the bottom board. Note: if VANC transport on
the encoder is turned off or an SDTi stream from another product is input and this switch is set to auto (off)
then group 1 will be embedded to group 1 of the HD output video and group 2 if it is present will be
embedded to group 2 of the HD output video.
