Albalá Ingenieros | Manual AEM3000C01
• The AEM3000C01 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Power considerations
The UR3000 and UR3100 mounting frames can house as many AEM3000C01 modules as
will fit in them.
3.5. Module configuration
Before installing the module in the mounting frame the input signal level must be
adjusted for its full scale value. Each of the four analog audio input channels has a
program jumper for setting the full scale value to between 15 and 28dBu in 1dB steps.
The AEM3000C01 comes from the factory programmed with full scale values of 22dBu.
The AEM3000C01 also includes a block of DIP switches for selection of the desired
operating mode upon startup. This configuration can be changed later using the control
software if the mounting frame where the module is installed also has a
communications controller.
- Switch 1 is used to deactivate the insertion function. When no audio is embedded
the SDI video at the output of the module is exactly the same as the input being
received.
- Switch 2 activates the function that erases all the audio groups embedded in the
incoming SDI video signal.
- Switch 3 is used when a single AES/EBU stream (two audio channels) is to be inserted
into one group.
- Switch 4 is used for selection of the bit length of the audio when it is embedded.
When 24 bits is selected then extended audio packets are used to embed the 24 bit
signals obtained from the A/D converters.
- Switches 5, 6 and 7 are not used and can be left in either position.
