Audio Expansion Modules
Audio expansion modules increase the number of inputs and outputs, and expand the functionality of
the FS1 and XD1 modules. When an expansion module is installed beside an applications module, an
automatic connection takes place. The
Configuration
section of the user interface is updated, giving the
user setup, control and monitoring functions. Audio signals are automatically connected internally over
bidirectional high-speed buses, eliminating the need for external cables.
Up to two
audio
expansion modules can be placed beside an XD1 or FS1 application module. (Audio
expansion modules are installed to the right—in a
higher
numbered slot—beside an FS1 or XD1.) The
two audio expansion modules may be installed in any of the following configurations:
•
Digital
•
D Analog
•
D Digital
•
Analog
Analog expansion modules use the SEL-BM-AA back module, which connects directly to the front
module. However, SEL-BM-AESB AES back modules require an additional submodule, installed at the
rear of the front module.
If a SEL-BM-AESB digital back module is installed without this submodule, the expansion module will not
be damaged, but it will not provide a signal of any type. On the other hand, if a SEL-BM-AA analog back
module is installed with an AES submodule/front module combination, the product
will
act as an
analog
expansion module.
For a list of Audio Expansion Configurations, see Table.
