AJA FS4 Synchroniseur de trame et convertisseur 4K/UHD

The AJA FS4 is a 1RU frame synchronizer and up/down/cross converter that handles 4K/UHD, 2K/HD, and SD video formats. Its strongest capability is simultaneous processing of four independent 3G-SDI channels or a single 4K/UHD signal, with full audio and ancillary data support.

Advantages

The FS4 combines frame synchronization, format conversion, color correction, and HDR support in a compact 1RU chassis with dual redundant power supplies. It offers flexible connectivity with 4x 3G-SDI and HDMI 2.0 inputs and outputs, plus comprehensive audio I/O including AES/EBU, MADI, and analog. Control via Ethernet, RS-422, or front panel ensures easy integration.

Suitable for

• Broadcast and production facilities requiring multi-channel SDI processing
• 4K/UHD workflows needing frame sync and HDR conversion
• Live events and OB vans with space and power constraints
• Post-production suites needing color correction and audio routing
