Overview
The SRG-4400 is designed for high stability Master Sync operation. The product can provide a
wide range of accurate reference signals including analog composite video, analog composite
black-burst, tri-level sync, SD, HD and 3G serial digital (SDI) video, and SD, HD, and 3G SDI
black. Additionally, there are AES/EBU digital audio outputs, an external frequency reference
input, and a GPS input.
The SRG-4400, in its base configuration, is supplied as a Composite SPG with multiple Color
Black and SD-SDI outputs. The Color Black outputs are configured to be capable of providing
tri-level syncs. A sub-module also provides an interface for additional signals including
AES/EBU digital audio outputs, analog audio outputs, LTC outputs, a GPS input, and an external
frequency reference input.
Additional options above the base configuration are enabled using special Option Keys. These
options are: GPS (SRG-4400-GPS) and NTP (SRG-4400-NTP). The connectors and associated
hardware for these options will already be present, the Option Keys simply enable the GPS or
NTP option.
The SRG-4400 comes standard with a dual power supply unit (PSU) configuration which has two
PSU installed into the front of the unit, and can be “hot-swapped” should problems be
encountered.
A companion automatic changeover unit, the ACO-4400A, is also available.
