In this mode, the channels of the group are mapped directly to the bank channels. For
example channel 1 in the selected group is de-embedded to channel 1 of the selected
bank. Channel 2 in the selected group is de-embedded to channel 2 of the selected
bank etc.
Cycling through the banks using the BANK button, allows the user to determine which
banks are currently enabled for de-embedding and will also show the source group for that
bank.
Channel Mode
In channel mode, de-embedding is controlled on a per channel basis. So individual
channels within a group are selected to be output on a particular channel within a bank.
To de-embed a group channel of audio to a specific bank channel.
1
Select the output bank number using the BANK button.
2
Select the output bank channel using the BANK CHANNEL button.
3
Select the group to de-embed using the GROUP button.
4
Select the group channel to de-embed using the GROUP CHANNEL button.
To enable de-embedding to this channel, both the BANK and BANK CHANNEL must be
enabled. This is indicated by the button LED being lit green. If either are red, then simply
enable them by holding down the relevant button for two seconds.
Cycling through the banks and bank channels using the BANK and BANK CHANNEL buttons
respectively, allows the user to determine which bank channels are currently enabled for
de-embedding and will also show the source for that bank channel.
Deleting Audio Groups
If the SDI video signal contains audio groups which require deleting, then these can be
deleted on a per output basis. For example if the video input contained all four audio
groups then it is possible to delete all groups on output 1 and only groups 1 and 2 on
output 2.
The unit will also delete any ancillary packets marked for deletion and realign the packets
to make maximum use of the available ancillary space.
To delete audio groups the unit is put into a special group deletion mode. To enter this
mode press and hold the STATUS button for 5 seconds. The front panel button indicators
will change so that only the GROUP, GROUP CHANNEL and STATUS buttons are available.
The GROUP button and indicators are used to select the group number, the GROUP
CHANNEL button is used to enable or disable deletion on this group and the STATUS
button is used to select the output. Once the desired settings have been set, then using
the same method to enter the group deletion mode will exit it. The new settings will be
applied as soon as the unit returns to its normal operating mode.
