manual) will be embedded into the HD stream.

5.11. SELECTING AUDIO DELAY (TOP BOARD)
DIP switch 6 on the top card controls the audio delay through the card. Since the Evertz 7771CS does not
delay the audio to synchronize it with the video a longer delay is needed in the 7771DS when the 7771CS
is it’s SDTi source. If a Sony generated SDTi source is used a shorter audio delay is needed since the
SDTi input to the 7771DS will then have the audio and video in sync.

5.12. SELECTING THE ANALOG AUDIO SOURCE CHANNEL (TOP BOARD)
The 7771DS supports two groups of audio or 4 stereo pairs however only has one stereo pair of analog
monitor output. DIP switches 7 and 8 on the top card select which of the four stereo channels transported
is output to the analog monitor channels.

5.13. SELECTING HOW THE AUDIO WILL BE OUTPUT (BOTTOM BOARD)
Up to 2 groups of 4 audio channels can be de-embedded from the 270 Mb/s SDTi bit stream and either be
re-embedded on the HD video output or output as AES audio. DIP switch 1 on the bottom board controls
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 1 DIP 2 DIP 3 Audio Group 1 Destination
Off --- --- AES outputs 1 and 2
On Off Off HD Output group 1
On Off On HD Output group 2
On On Off HD Output group 3
On On On HD Output group 4
Table 10: Audio Group 1 Destination Selection Switch Settings
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.

5.14. SELECTING IF AUDIO GROUP 2 IS ENABLED OR DISABLED (BOTTOM BOARD)
DIP switch 7 on the top 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.

5.15. AUDIO OUTPUT AUTO/MANUAL SELECTION (BOTTOM BOARD)
DIP switch 8 on the top 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.

5.16. ANALOG AUDIO MONITOR VOLUME
The toggle switch is used to control the volume of the analog audio outputs. Pressing the switch up (away
from the card ejector) increases the volume, and pressing the switch down (towards the card ejector)
decreases the volume.
