Description
The EVS XT3 is a professional live production server engineered for broadcasters and production companies requiring multi-channel HD and 4K content capture, management, and instant replay capabilities. With 8-channel simultaneous I/O, the XT3 delivers synchronized recording and playback of high-bitrate video streams at up to 1.5 Gbps per channel, making it ideal for live sports, news, and outside broadcast van operations. The server features flexible input/output configuration supporting HD-SDI, 3G-SDI, IP via Fiber and Ethernet for seamless integration into hybrid SDI and modern IP-based broadcast infrastructures. Real-time ingest, advanced metadata tagging with searchability, and native timeline-based editing enable operators to assemble highlight reels and execute instant replay with variable speed control during live events. The XT3's configurable modular storage architecture scales from HD through 4K UHD at 60fps, with multi-channel record and playback operating simultaneously for true production flexibility. Its proven reliability and performance make it the industry standard for premium live broadcast production worldwide.

FAQ
What SDI generations and IP protocols does the XT3 support for integration into existing broadcast chains?+
The XT3 supports HD-SDI, 3G-SDI, and IP-based connectivity via Fiber and Ethernet. For IP workflows, verify firmware version and licensing for ST 2110 compliance with your systems integrator, as protocol support may depend on configuration. This flexibility allows integration into both legacy SDI infrastructures and modern IP-based OB vans. Confirm port assignments during pre-sale design to match your router and control infrastructure.
Can the XT3 simultaneously record and play back across all 8 channels, and what are the bitrate limits per channel?+
Yes, the XT3 supports multi-channel record and playback simultaneously. Recording bitrate reaches up to 1.5 Gbps per channel. At full 8-channel capacity, total aggregate throughput must be managed within your storage and network architecture. For 4K 60fps workflows, confirm your SAN or modular storage configuration supports sustained throughput before committing to production schedules, especially in high-action sports scenarios.
What storage architecture does the XT3 use, and how is capacity configured for OB van deployments?+
The XT3 features a configurable modular storage architecture; capacity is not fixed. Exact SSD or HDD modules, RAID configuration, and total GB/TB depend on your order specification and intended session length. For mobile units, work with EVS and your integrator to calculate storage needs: bitrate ร duration ร channel count. Redundancy options and hot-swap capability should be confirmed during system design to minimize downtime in live event environments.
How does the XT3 integrate with external control surfaces, CCUs, and routing infrastructure?+
The XT3 provides advanced metadata support and networking integration for control. Integration with CCUs, RCPs, and routers depends on control protocol compatibilityโtypically Ethernet-based APIs and industry-standard interfaces. Verify with EVS and your control system vendor that your specific mixing console, routing switcher, or production control surface supports XT3 automation and metadata exchange. Timeline-based editing is native; external triggering requires protocol confirmation.
What frame rates and video formats are supported, and are there constraints for 4K at highest speeds?+
The XT3 supports HD, Full HD, and 4K UHD up to 60fps. At 4K 60fps, bitrate per channel approaches or meets the 1.5 Gbps ceiling, reducing simultaneous channel capacity if all channels run maximum format. Plan your I/O mix carefully: consider running lower frame rates (24p, 30p) on some channels to preserve bandwidth for critical 4K feeds. Firmware and codec options (if configurable) should be verified during specification phase.
What are the connectivity and power requirements for integrating the XT3 into a mobile production unit?+
The XT3 integrates SDI, IP (Fiber and Ethernet), and networked control. Exact power consumption and cooling requirements depend on configuration; confirm total watts and thermal output with EVS before sizing generator and ventilation for your OB van. Fiber connectivity reduces cabling weight and EMI in tight mobile spaces. Plan for UPS backup on control and metadata networks; live replay cannot tolerate control interruptions. Work with your integrator on cable routing and redundancy.
Is the XT3 suitable for unlimited instant replay sessions, and what are operational limits on clip length or number?+
The XT3 delivers instant replay with variable speed control and real-time editing. Practical limits depend on available storage, bitrate, and frame count. A complete workflow requires defined session templates, metadata indexing discipline, and timeline management. Operators must clear or archive completed clips to maintain headroom for live capture. For 90-minute live sports broadcasts, confirm your modular storage handles sustained ingest, multiple replay playouts, and edit cache simultaneously without performance degradation.
What redundancy and serviceability options are available for mission-critical live broadcasts?+
The XT3 supports multi-channel architecture, enabling some degree of operational redundancy through channel isolation. Full redundancy (dual servers, hot standby) is a deployment choice, not native to a single unit. Modular storage supports hot-swap components. Maintenance and serviceability specificsโincluding spare parts availability, MTTR, and field upgrade pathsโmust be confirmed with EVS and your support contract. For critical events, plan dual-XT3 architectures or integrated failover workflows with your systems integrator.
How does the XT3 handle metadata tagging and searchability in a multi-operator, fast-paced live sports environment?+
The XT3 includes advanced metadata tagging and searchability capabilities, enabling operators to mark highlights, scoring moments, and editorial flags in real time. Searchability depends on consistent metadata discipline and backend integration with your MAM or NLE system. Timeline-based editing leverages these tags for fast clip assembly. In high-tempo sports, confirm user interface responsiveness, keyboard shortcuts, and metadata template automation to avoid operator bottlenecks during live coverage.
Are your used / ex-demo units tested and warranted?+
Yes. Our used and ex-demo units undergo a full functional inspection โ sensors, video outputs, control signals, optics and mechanics โ including a colorimetry and sensitivity test. Each product is tested by our technicians and comes with a 90-day warranty. Contact us for the specific warranty terms of the unit you are interested in.
