EXT-3GSDI-441 specifications

The Gefen EXT-3GSDI-441 is an advanced SDI (Serial Digital Interface) splitter designed for professional broadcast and production environments. It is a versatile solution that allows a single SDI input to be split into four identical outputs, making it an essential tool for video distribution in high-definition applications. This device supports 3G-SDI, which allows for high-definition video transmission at 1080p resolutions, ensuring that the output remains crystal clear and free from signal degradation.

One of the primary features of the EXT-3GSDI-441 is its support for dual-link and single-link SDI formats, offering flexibility for various production needs. It can handle different video formats, including standard definition (SD) and high-definition (HD), making it suitable for a wide range of applications from live broadcasting to post-production environments. The device is also backward compatible with older SDI formats, allowing it to seamlessly integrate into existing setups.

In terms of technical specifications, the Gefen EXT-3GSDI-441 supports a maximum data rate of up to 2.97 Gbps, facilitating the transmission of uncompressed video signals. The unit features active circuitry that ensures signal integrity over longer distances, typically handling cable runs of up to 300 feet (90 meters) at high-definition resolutions without the need for additional signal boosting.

The EXT-3GSDI-441 is designed with the operational needs of professionals in mind. It includes status LED indicators for power and signal presence, allowing users to easily monitor the functionality of the device. Additionally, its compact rack-mountable design is convenient for integration into equipment racks, maximizing workspace efficiency while maintaining a clean setup.

Another notable characteristic of the EXT-3GSDI-441 is its robust construction, which ensures durability in demanding environments. The device operates quietly and efficiently, generating minimal heat during usage.

Overall, the Gefen EXT-3GSDI-441 SDI splitter is a reliable and feature-rich solution for video professionals looking to enhance their workflow and manage multiple outputs from a single source, making it an invaluable addition to any broadcast or production facility.
