Chapter 1: Introduction
Product Description
AVM-3901-B, -C, -B4, and -C4 modules are multiplexer/synchronizers
designed for standard definition video.
AVM-3901-B and -C modules support two AES audio inputs and two
AES processed outputs in balanced (AVM-3901-B) and unbalanced
(AVM-3901-C) formats. AVM-3901-B4 and -C4 modules support four
AES inputs in balanced (AVM-3901-B4) and unbalanced
(AVM-3901-C4) formats.
All versions provide an SDI video input and two SDI video outputs for
video containing embedded audio, as well as an internal video frame
synchronizer and a genlock input with loopback.

Chapter 1: Introduction
In NEO frames, back modules are placed directly behind the front
modules. Back modules are designated by the suffix “-BM.” For
example, the back module of the AVM-3901-B is the
“AVM-3901-B-BM.” See Figures 1-2 to 1-5 for illustrations of the
AVM-3901-B, -C, -B4, and -C4-BM back modules.
