To enable embedding to this group and channel, both the GROUP and GROUP 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. Embedding will
only take place if the GROUP is enabled. If the GROUP CHANNEL is enabled and the GROUP
is not, then no embedding will occur.
Cycling through the groups and group channels using the GROUP and GROUP CHANNEL
buttons respectively, allows the user to determine which groups are currently enabled for
embedding and their sources.
SD & 24-bit Audio
The Redbox embedders provide full support for 24-bit audio embedding in SD by making
use of the extended data packets as per SMPTE-272M. By default the unit embeds 20-bit
audio. To enable the full 24-bit embedding, this must be set through the remote control
port.
Before enabling this option, ensure that any receiving equipment is capable of handling
the extended data packets.
De-Embedding
The unit is always de-embedding, automatically reading all the audio data contained in the
video signal as it appears to the de-embedding block. Using the front panel controls the
user can control which of these channels or groups within the video input are routed to the
analogue outputs.
If an SD video signal is being received and extended audio data is detected, then the unit
will automatically use this to reproduce full 24-bit audio data and no user intervention is
required.
Bank Mode
In bank mode de-embedding is controlled on a per group basis. So groups are selected to
be output on a particular bank.
To de-embed a group of audio to a specific bank.
1
Select the De-Embed function using the FUNCTION button.
2
Select the audio bank, using the BANK button.
3
Select the group to de-embed using the GROUP button.
The BANK button LED will show whether the bank is enabled. To enable de-embedding to
this bank, press and hold the BANK button for two seconds, until the button turns green.
This indicates that de-embedding is enabled to this bank. To turn off de-embedding, then
hold the BANK button down until the button turns red. The bank number indicator will
blink to show that the change has been applied.
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.
