Description
Product Overview
The 3G-SDI 1x4 Distribution Amplifier is a broadcast-grade, pure hardware video splitter designed to seamlessly distribute a single 3G-SDI input into four identical, synchronized 3G-SDI outputs without signal loss. Built for maximum reliability, plug-and-play simplicity, and compact portability, this high-performance splitter is engineered to support demanding, continuous broadcast and professional AV operations.
Equipped with an advanced internal re-clocking chip, automatic cable equalization, and signal amplification, it ensures rock-solid, ultra-high-definition video transmission over long distances (up to 150 meters). Beyond the standalone mini-chassis form factor, it supports multi-channel high-density rackmount deployments—scalable to 4x16, 8x32, or 16x64 configurations in standard 1U/2U/3.5U chassis.
Key Features
- 1-in-4-out Distribution: Effortlessly splits 1-channel 3G-SDI input into 4-channel 3G-SDI outputs.
- Re-Clocking & Signal Amplification: Integrated SDI re-clocking and automatic cable equalization maintain pristine signal integrity and extend 3G-SDI cable runs up to 150 meters (492 ft).
- High-Density Scalability: Flexible architecture supports standalone box deployment as well as high-density 1U, 2U, and 3.5U centralized rackmount systems (up to 16x64 distribution).
- Embedded Audio & ASI Support: Fully supports embedded SDI audio pass-through, audio-video synchronization, and ASI-SDI signal distribution.
- Full HD Resolution: Supports resolutions up to 1080p@60Hz, with backward compatibility for lower SD/HD formats.
- Plug & Play / Hot-Swappable: Pure hardware architecture with no driver required; supports hot-swapping for uninterrupted production workflows.
- Wide Voltage Input: Designed with a 5V–12V wide-voltage DC power supply for enhanced stability and operational safety.
Target Applications
- Designed specifically for mission-critical visual environments, including:
- Broadcast & Live Production: Non-linear editing (NLE) suites, broadcast studios, control rooms, and OB vans (outside broadcast trucks).
- Pro AV & Staging: Live event broadcasting, multimedia displays, and staging demonstrations.
- Enterprise & Security: HD video conferencing, centralized display management, and high-definition surveillance monitoring.
