J-Tech Digital SDI Splitter 1x4 — 1320 ft SD/HD/3G-SDI

The J-Tech Digital SDI Splitter is a compact 1-input, 4-output signal distributor that repeats and equalizes SD, HD and 3G-SDI feeds for long runs up to 1320 ft (SD) using Belden 1694A cable.

This rugged metal-encased converter takes one SDI source and outputs four identical SDI streams while regenerating the signal to preserve timing and picture integrity. It automatically detects incoming SDI rates (270 Mbps, 1.485 Gbps, 2.97 Gbps) and provides wide DC input tolerance for flexible power options on location or in permanent installations.

How does the splitter maintain signal quality for long cable runs?

The unit includes an SDI repeater function that equalizes and re-clocks the incoming stream, reducing jitter and compensating for cable loss so downstream devices receive a stronger, cleaner signal. That regeneration is what enables extended transmission distances without adding complex signal processing gear.

• Re-clocking and equalization to restore signal edges and timing
• Supports 1320 ft for SD-SDI, 660 ft for HD-SDI, 330 ft for 3G-SDI over Belden 1694A
• Delivers four simultaneous, identical SDI outputs from one input

What video formats and rates are supported?

The splitter is compatible with standard-definition (SD-SDI), high-definition (HD-SDI) and 3G-SDI rates, covering common broadcast and professional camera outputs. It auto-senses the input format so you don’t need to configure modes when swapping cameras or sources.

• SD-SDI: 270 Mbps
• HD-SDI: 1.485 Gbps
• 3G-SDI: 2.97 Gbps
• Automatically detects and locks to incoming SDI rate

How is the device powered and installed in field workflows?

J-Tech designed the splitter with a wide DC voltage window (5–30 V) so it fits many on-site power scenarios, from small battery packs to centralized power systems. The metal enclosure withstands typical rack or field use, and the unit is plug-and-play—no drivers or setup required.

• Wide voltage input: DC 5V–30V (operates at minimum 5V)
• Durable metal housing for longevity in installs and transport
• Simple BNC connections: one input, four outputs for straightforward cabling

What support and warranty does J-Tech Digital provide?

Each splitter includes J-Tech Digital’s one-year warranty and complimentary lifetime technical support, so you can troubleshoot signal issues or installation questions with the manufacturer. The product’s simplicity and documentation make it suitable for quick integration into live productions or AV systems.

• One-year limited warranty from J-Tech Digital
• Free lifetime technical support for setup and troubleshooting
• Plug-and-play operation minimizes configuration time

Who is this for? The J-Tech Digital 1-in/4-out SDI Splitter is aimed at camera operators, broadcast engineers, AV integrators and event technicians who need a reliable, low-profile solution to feed multiple monitors, recorders or switchers from one SDI source. It fits compact OB vans, fixed installations and pop-up production rigs where long cable runs, flexible power and repeatable, clean SDI outputs are required.
