| DA4 12G HD-SDI | Four Output 12G-SDI
Distribution Amplifier |
60-1674-02 |
The DA4 12G HD-SDI is a compact four-output distribution amplifier for multi-rate SDI digital video signals. It supports all common serial digital video data rates up to 11.88 Gbps, while passing HDR, up to 16 channels of embedded audio, and other ancillary data allowed by the SMPTE and ITU standards. Automatic input cable equalization adds up to 984 feet (300 m) for SDI, 787 feet (240 m) for HD-SDI, 590 feet (180 m) for 3G-SDI, 295 feet (90 m) for 6G-SDI, and 230 feet (70 m) for 12G-SDI digital video, when using RG6 cable. The DA4 12G HD-SDI is housed in a quarter rack width, metal enclosure, providing integration-friendly mounting options into both new and existing AV systems.
