Setting up audio

English Manual 21

Setting up audio

To set up audio, go to Frame / System / I/O / SDI.

Use this page to display information about in-

coming audio, select audio for processing and

change Advanced SDI settings.

SDI Status indication section

Lock status indicator

The Lock status field shows the top level status

of lock to an incoming SDI stream. When UpCon

is locked to an acceptable SDI stream on the SDI

input, “Lock” is shown. When no acceptable SDI

stream is available on the SDI input, “No Lock”

and a red LED will be shown in this field.

Format indicator

When the UpCon is locking to an incoming SDI

stream, the Format indicator field will show the

format – e.g. “1080i59.94 HD”. If the UpCon is

not locking to any incoming SDI stream, the For-

mat indicator field will read “N/A”.

Available Groups indicators

SDI with embedded audio carries up to 16 chan-

nels of audio, divided into four groups. Accord-

ingly, each group carries four channels of audio.

The four Available Groups indicators what audio

groups are available in the incoming SDI stream

for metering and processing. The on-screen LED

for each available group will light up in green.

If the UpCon is not locking to an incoming SDI

stream, all indicators are turned off.

Audio Groups selector

Use the Audio Groups selector to select audio

groups for metering and processing. Available

settings are “Groups 1+2” and “Groups 3+4”.

! Please note that the UpCon always receives

two of the audio groups in the incoming

stream. The unprocessed audio groups are

bypassed bit-transparently, as well as all re-

lated SDI packets such as video time code,

close captions etc.

Advanced SDI Mode section

The Advanced SDI Mode section contains SDI-

related settings that you would normally not have

to change.

Advanced settings switch

To change Advanced SDI settings, click the Ad-

vanced button in the Advanced SDI Mode sec-

tion of this page.

! Please note that switching off access to Ad-

vanced SDI settings will reset all parameters

in this section to their default values.

Clock Mode parameter

With SDI standards constantly evolving, chanc-

es are that upstream equipment treat audio and

video sync differently – e.g., a device may only

pay attention to one or the other. As this may

cause occasional disruption of sound, picture or

both, a problem may be difficult to trace without

measurement equipment monitoring SDI traf-

fic for weeks or months. To diagnose a poten-

tial problem, UpCon offers a diagnostic mode,

which may be tried after consulting TC support.

To activate diagnostic mode, set the Clock Mode

parameter to Diagnostic.

In Diagnostic mode, the UpCon will disregard

the audio clock information included in the audio

packets in the SDI stream and de-embed the au-

dio based on the video clock only.

! Use the Diagnostic setting for diagnostic pur-

poses only.

Audio Out Groups parameter

Use the Audio Out Groups parameter to define if

and how the group assignment of the processed

audio signals should be changed.
