Professional 4x4 SDI Matrix Switcher

The Vszerda 4x4 SDI matrix switcher routes four BNC SDI inputs to four independent BNC SDI outputs. It is built for broadcast studios, security operations and training venues that need reliable signal distribution across multiple displays.

Signal integrity and SMPTE compliance

The unit handles SD-SDI, HD-SDI and 3G-SDI formats with compatibility across SMPTE 259M-C, 292M and 424M standards. Output signal level is maintained at 800mVp-p for consistent transmission quality.

Resolution support up to 1080P at 60Hz

Supported input and output resolutions include 480i, 576i, 720P and 1080i at 50 or 60Hz, plus 1080P at 24, 25, 30, 50 and 60Hz. Buyers needing 4K or higher frame rates should select a different matrix.

Questions about this item

How do I install the Vszerda 4×4 SDI matrix and which step is often missed?

Connect each source to the four BNC SDI inputs and each display to the four BNC SDI outputs, then attach the included US power adapter; the step often missed is verifying that every cable run stays within the 800 mVp-p output range so the signal arrives at the far end without attenuation.

What maintenance or replacement will this switcher need later?

The unit has no user-serviceable parts and no cooling fans; plan only to replace the external power adapter if it fails and to inspect BNC connectors for corrosion during routine rack checks.

What limit appears first during sustained 3G-SDI operation?

The 800 mVp-p output level is the first constraint; on long coaxial runs the signal will drop below spec before the switcher itself reaches any thermal limit.
