Introduction
9374-Series Cards Functional Description
In this manner, the particular inputs and outputs required for a particular
application can be accommodated using a Rear Module that best suits the
requirements. The required input and outputs are broken out to the industry
standard connectors on the Rear Module; the unused inputs and outputs
remain unterminated and not available for use.
The full assortment of 9374-Series Rear Modules is shown and described in
9374-Series Card Rear Modules (p. 2-4) in Chapter 2, “Installation and
Setup”.

Embedded Audio
The 9374-Series cards support all four groups (16 channels) of
embedded audio at full 24-bit resolution in both SD (with extended data
packets) and HD for each of the card’s SDI streams.
Discrete AES Audio (AES-3id)
The 9374-Series cards can accept 16 channels (8 pairs) of discrete
AES audio on 75
Ω
BNC connections (maximum total of inputs and
outputs). Sample rate conversion is employed to accommodate sample
rate differences in the AES stream and the input video stream.
AES-3id outputs can be sourced from any SDI embedded channel,
MADI input, or other AES-3id inputs received by the card.
MADI Audio (AES-10)
The 9374-Series cards have a 75
Ω
BNC input and output connection
that supports the MADI standard of up to 64 channels input and output.
MADI outputs can be sourced from any SDI embedded channel,
AES-3id inputs, or other MADI channels received by the card.
(1) All rates displayed as frame rates; interlaced (“i”) field rates are two times the rate value shown.
(2) All inputs must be synchronous (e.g., all frame synced to same reference) to assure clean audio cross-routing between SDI
streams. Multiple simultaneous formats are supported on a limited basis (e.g., HD on SDI Inputs A/B and SD on SDI Inputs C/D).
AES-3id and MADI should also be synchronous with selected SDI stream(s) to ensure clean audio cross-routing.
