Studio Converter for Live Production

The Blackmagic Design SWRCONVRCK2 is a 1RU rack-mounted studio converter that links up to four remote camera converters over single-mode optical fiber. It provides four 10-bit SD/HD-SDI camera inputs and one program input with embedded tally data, making it suitable for multi-camera outside broadcasts, studio floors or large venue productions where cable runs exceed copper limits.

Thermals Noise and Power Draw

The unit operates from 110 to 220V AC at 50 or 60 Hz and also accepts a redundant 12 to 31V DC supply for backup installations. An IEC power cord is required but not included, and no redundant power supply is bundled. The compact 1RU chassis relies on passive cooling, so acoustic output remains low in typical control-room or OB-truck environments.

Sustained Load Behaviour

Optical fiber links support signal transmission up to 28 miles without repeaters, maintaining 10-bit SD or HD video quality over extended runs. Four bi-directional converters handle continuous camera return feeds, talkback with select, volume and mute, and tally routing simultaneously. The converter is compatible with Mac OS X 10.7 or 10.8 and later, plus Windows 7 and 8, for long-duration monitoring and control sessions.

Questions about this item

How do I install the SWRCONVRCK2 in a rack and what is the step people get wrong?

Mount the 1RU unit using the built-in rack ears in an 18.9 inch deep rack; the step often missed is connecting the IEC power cord and the separate 12 to 31 volt DC redundant feed, both required for full redundancy.

What maintenance or replacement will the SWRCONVRCK2 need later?

The four LC single-mode fiber connectors and the 3-pin XLR audio pairs should be inspected and cleaned periodically; the internal power supply has no user-serviceable parts and the redundant DC input should be tested annually.

What limit shows up first on the SWRCONVRCK2 under sustained use?

The optical fiber signal range is rated at 28 miles; beyond that distance the SD/HD video path degrades before any thermal or power limit is reached.
