2.2.4. EMR-OP48-AA Analog Audio Output Module
The EMR-OP48-AA is an analog audio output card for the EMR. It supports 48 stereo analog pairs (96
mono channels). Additionally, there is one MADI output, which can carry up to 64 additional channels of
audio giving a total of 160 channels of audio.
Note: Analog OP card will accept a TDM signal and will convert it to analog.
The latest firmware version de-multiplexes 160 channels of audio from 1 of 2 TDM input streams. One
stream is the primary and the other is the redundant. Either TDM stream can be used as the primary
since they are identical. The system can be configured to default to the redundant stream if the primary is
missing.
There is also one video monitoring output which can be used to visualize the audio levels using level
meters for each channel. This monitoring output is a 720p/59.94 signal that provides a visual confirmation
of audio presence and levels.
The EMR-OP48-AA rear panel occupies 2 slots in a frame and has 50-pin D-Sub female connectors as
shown in Figure
2-15. The analog outputs are interfaced by the six 50-pin D-Sub female connectors.
Each connector supports 8 stereo pairs of analog audio. The pin out for each connector is shown in
Table
2-9. All other I/O signals use DIN 1.0/2.3 connectors. The control of the monitoring ports is not
currently supported.
The connectors labeled TDM1 and TDM 2 are the main and redundant TDM inputs respectively, TDM 6 is
the video output and the connector labeled MADI1 is a MADI output.
