Control Modes
There are two modes available to control the de-embedding channel routing process.
These are the BANK mode and the CHANNEL mode.
Bank Mode
In Bank mode, audio is routed on a per bank basis, so when controlling de-embedding a
group of audio is selected to be sent to a bank.
Channel Mode
In Channel mode, audio is routed on a per channel basis, this allows for maximum flexibility
when de-embedding, allowing any channel within any group be sent to any channel of any
of the available audio output banks.
Changing Control Mode
To switch between Bank and Channel control modes, simultaneously press and hold
the GROUP CHANNEL and BANK CHANNEL buttons for 5 seconds. The mode will switch
after this time and the button can be released. Bank mode is in use when both the BANK
CHANNEL and GROUP CHANNEL button LEDs are not lit. Conversely, when Channel mode
is in use these two LEDs are lit.
When switching from Channel to Bank mode, all channel mappings are reset to default.
When switching from Bank to Channel mode, the channel mappings are retained to allow
for further modification.
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 whole groups are
selected to be output on a particular bank.
1
To de-embed a group of audio to a specific bank.
2
Select the output bank number, 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.
