Inputs
FS1 and XD1 modules support embedded-audio input, AES audio input, and analog audio input (when
using an analog audio expansion module). In addition, they process embedded audio from the SDI video
input in SD, HD, or 3G (Level A and Level B-DL) formats, and include two independent audio de-
embedders—each supporting sixteen mono channels. Any de-embedded group may contain
compressed audio, linear PCM, or a combination of both.
When used separately, the XD1 supports up to eight AES inputs.
Note
: AES inputs can be disabled by the
Green-Power Save
control (
Misc > Green-Power Save
). If an
AES input is grayed out in the user interface, check its power save status.
Audio Expansion Modules
Optional analog and AES expansion modules are available to provide additional audio capacity. The AES
SELOPT-DAEX-AESCS and SELOPT-AAEX-AABS expansion module supports eight AES inputs, and the
analog SELOPT-AAEX1-AABS audio expansion board supports four channel pairs of analog input. Each of
the sixteen mono audio channels can be swapped.
In the parameter lists of the FS1 and XD1, expansion module options appear with the prefix
Exp
. When
expansion modules are not installed, these parameters are not visible.
CAUTION:
Audio expansion modules and application modules such as the XD1 work as a system. To prevent audio
"pops," ensure that you do
not
perform the following actions when using a live application module:
•
Insert or remove an expansion module
•
Change the power status of an expansion module
Outputs
The FS1 and XD1 outputs up to 72 audio channels, including the following:
•
16 embedded channels from Embedder 1
•
16 embedded channels from Embedder 2
•
16 channels for up to 8 AES inputs
•
16 channels for up to 8 AES inputs from the optional AES expander module
•
8 analog mono inputs from the optional analog expander module
Additionally, up to 32 channels are available from the optional Advanced Audio Processing block.
Any of these source channels can be routed to any destination.
