Datavideo VP-633 3G-SDI Re-clocking Distribution Amplifier 1x3

When a single SDI feed must reach multiple destinations without signal degradation, the VP-633 steps in with active re-clocking and equalization that preserve integrity over long cable runs. Unlike passive splitters that weaken the signal, this 1x3 distribution amplifier regenerates the SDI stream for each output, ensuring every connected device receives a clean, stable signal.

Highlights

• Distributes one 3G/HD/SD-SDI input to three identical outputs
• Active re-clocking and automatic equalization for long cable runs
• Supports data rates up to 2.97 Gbps (3G-SDI Level A/B)
• Metal housing with ESD protection for reliable field or studio use
• LED indicators for power and input lock status

In daily use

The VP-633 is a compact, dependable tool for broadcast, live event, and post-production environments. Connect a camera, switcher, or router output and feed monitors, recorders, or additional switchers without worrying about signal loss. Automatic format detection handles SD, HD, and 3G signals seamlessly, while the built-in cable equalizer compensates for attenuation up to 100 meters on 3G-SDI, 150 meters on HD-SDI, and 300 meters on SD-SDI using Belden 1694A cable. The included 12V DC power supply keeps it running, and the optional RMK-2 rackmount kit allows for tidy installation in a standard 19-inch rack.
