FS4 Frame Synchronizer/Converter v1.1
Chapter 1: Introduction
Overview
FS4 is AJA’s flagship frame synchronizer and converter, offering incredible versatility and
connectivity in a sleek and compact 1RU frame for all your 4K/UltraHD/2K/HD/SD
conversion needs. Offering huge flexibility and the power to adapt to meet the needs of
rapidly changing environments, FS4 offers two modes to deal with your 2K/HD/SD
multichannel needs as well as your 4K/UltraHD pipelines.
In Four Channel Mode, FS4 can be used as four separate Frame Synchronizers/Format
Converters for 2K/HD/SD projects with separate color correction and proc amp controls
for each.
In Single Channel Mode you can handle a complete 4K/UltraHD/2K/HD/SD feature set
including up, down, cross-conversion, 2SI compatibility and unparalleled video
connectivity with I/O options for 4K/UltraHD including Quad 1.5Gb, Dual 3Gb, Quad 3Gb
and 6Gb, 12Gb over optional SFP modules.
FS4’s extensive digital video connectivity is only matched by its expansive digital audio
flexibility. The growth of 5.1 and 7.1 audio has increased the number of audio channels
that must be managed in a production as well as needing to create stereo mixdowns
from 5.1 and 7.1 sources. The MADI standard provides a convenient way to transport
large numbers of audio channels along a single cable, simplifying the cabling demands
for broadcasters, mobile trucks and production. FS4 supports both fiber and coax
connections with 128-channel MADI input and output. An internal 277x208 audio matrix
allows full routing of MADI, mixdowns and all audio coming from SDI, fiber and AES
sources for an incredible amount of audio processing capability in a single box.
