The What: Extron Electronics has introduced the new DA4 12G HD‑SDI, a compact four‑output distribution amplifier for multi‑rate SDI digital video signals.
The What Else: It supports all common serial digital video data rates up to 11.88 Gbps, while passing HDR, embedded audio, and other ancillary data allowed by the SMPTE and ITU standards. Automatic input cable equalization adds up to 984 feet (300 meters) for SDI, 787 feet (240 meters) for HD‑SDI, 590 feet (180 meters) for 3G-SDI, 295 feet (90 meters) for 6G-SDI, and 230 feet (70 meters) for 12G-SDI digital video, when using RG6 cable. Automatic output reclocking reshapes and restores signal timing at each output for added headroom when connecting multiple devices.
"The DA4 12G HD-SDI supports the latest SMPTE standards and compliments our growing 12G-SDI product line," said Casey Hall, vice president of sales and marketing for Extron. "Customers now have a convenient option for sending 4K capable, multi-rate SDI long distances to multiple locations in broadcast, production, medical imaging, and other demanding applications."
The Bottom Line: 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.
