9035 PRODUCT MANUAL

9035-OM (V4.4)

DashBoard™ shows
Framesync Status error
message in 9035 Framesync
function submenu screen.

Specified Minimum Latency
Frames setting exceeds 9035
card buffer space for the
selected output video format

• Reduce the Minimum Latency Frames setting as

specified in the error message to correct the
error.

Note: Due to card memory limits, the maximum

available Minimum Latency Frames is
related to the output video format
selected.

For example, with a 1080i 5994 output,
the maximum setting is 5. For a 1080i film
(2398) output, the maximum setting is 3
(due to the increased buffer space
needed for the slower frame rate).
Conversely, greater maximum settings
are allowed for SD formats such as 525i
5994, where the practical maximum limit
is 13.

Video/audio synchronization or
delay noted.

Source synchronization
condition

• Use the Video Audio Delay Offset Control to

compensate for video/audio delay.

Refer to Framesync function submenu tab on
page 3-16 for more information.

Unsmooth, “jerky” motion
observed on video output with
Framesync set to lock to input
video.

Incompatible negative H/V
delay value user setting of
Vertical Delay or Hoeizontal
Delay controls

Negative vertical or horizontal delay values (using
the controls below) should not be used when using
Input Video mode. To add an offset in this case,
instead apply a positive value that results in the
desired net offset.

Analog VITC waveform
timecode not received and/or
processed.

Card erroneously set for
NTSC signal with 0 IRE of
setup with input containing
setup.

If analog VITC timecode source contains
7.5 IRE of setup, make certain
Video Signal Controls –> NTSC Contains is set
to 7.5 IRE of Setup.

If this is not done, analog VITC waveform may not
be received and processed by the card.

DashBoard™ shows red

Audio icon and Analog Input
Clipping message in 9035
Card Info pane.

• Card edge display shows

code

.

Analog peak audio input on
selected input exceeds +24
dBu level

• Reduce analog audio level at the source.

Note: 9035 audio gain controls cannot be used

to correct analog input overload condition.
The condition must be corrected at the
source.
