2.2.3. EMR-IP48-AA Analog Audio Input Module
The EMR-IP48-AA is an analog audio input card for the EMR. It supports 48 stereo analog pairs (96 mono
channels). Additionally, there is one MADI input, which can carry up to 64 additional channels of audio
giving a total of 160 channels of audio.
The EMR-IP48-AA consists of two identical half modules to reduce the failure block of the analog
component. The latest version of firmware takes the 48 channels of audio from each half module and the
MADI input, and multiplexes them onto 2 TDM streams. One stream is the main and the other is the
redundant. Either TDM stream can be used as the primary since they are identical.
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-IP48-AA rear panel occupies 2 slots in a frame and has 50-pin D-Sub female connectors as
shown in Figure
2-13. The analog inputs 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
All other I/O signals use DIN 1.0/2.3 connectors. The control of the monitoring ports is not currently
supported.
The TDM 1 and TDM 5 connectors are the main and redundant TDM outputs respectively. TDM 3 is the
video output and the connector labeled MADI2 is a MADI Input.
Please Note: It is necessary to set the IP address on both half modules. Also, the user
must load code on both half modules. The left module’s IP address will be used for
Winsetup & VLPRO.
Please Note: Cards will talk to one another through a link on the rear plate.
