4x1 SDI Switcher

This SDI switcher routes up to four BNC serial-digital inputs to a single BNC output. It accepts SD-SDI, HD-SDI and 3G-SDI formats at speeds from 143 to 2,970 MB/s. Professional video crews, broadcast facilities and security operators use it to select one live feed for monitoring or recording. The unit ships new with a US power adapter and a user manual.

Suits multi-camera productions

Ideal for operators who need to toggle between several SDI cameras or sources on one monitor. Not suitable for workflows that require simultaneous multi-view output, format conversion, HDMI or DisplayPort connectivity, or IP-based routing. Buyers needing more than four inputs or integrated scaling should look at a different class of router.

SMPTE 424M, 292M and 259M-C compliance

The switcher meets SMPTE 424M, SMPTE 292M and SMPTE 259M-C standards, guaranteeing compatibility with 480i, 576i, 720p and 1080p signals at 24, 25, 30, 50 and 60 Hz. Verify that every source and the destination device follow these same standards before purchase.

Questions about this item

Does the BNC SDI input ports on this 4x1 switcher need periodic cleaning or replacement?

The four BNC SDI input ports are passive connectors; they only need occasional dust removal with compressed air and do not require scheduled replacement.

What is the first limit reached when running four 3G-SDI streams continuously at 2970 MB/s through this switcher?

The 2970 MB/s SDI speed ceiling is the hard bandwidth limit; sustained 3G-SDI traffic cannot exceed this rate on the single BNC SDI output.

How much heat and fan noise does the unit produce when powered by the US adapter and switching 1080p60 signals all day?

The 0.57 kg metal chassis runs passively with no fan, so it stays warm to the touch but generates no audible noise during continuous operation.
