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.
Chapter 1: Introduction Main Features AVM-3901-B, -C, -B4, and -C4 modules have the following main features: • SDI video input with auto-detect • Two SDI video outputs • Internal video frame synchronizer • Two AES input channels (-B and -C versions) or four AES input channels (-B4 and -C4 versions) •...

External connections are not required for this feature. The AVM-3901-B, -C, -B4, and -C4 modules can be used as part of an audio tracking pair. To use this feature, install the AVM-3901-B, -C, -B4, and -C4 video modules directly above the audio module.
Firmware Firmware upgrading is a routine procedure that you must perform to install newer versions of software on the AVM-3901-B, -C, -B4, and -C4 modules. Pilot, Co-Pilot, or Navigator software applications are required for this procedure. You can use either the Discovery or the drag-and-drop method.
