With dual-channel conversion and frame synchronizing in a slim 1RU space, FS2 can do the work of two separate devices or combine both processors together for maximum flexibility.

Dual video and audio processors

Offering huge flexibility and the power to adapt to meet the needs of rapidly changing environments, FS2 offers unprecedented conversion and frame synchronization power in a single 1RU space.

FS2 can be used as two separate Frame Synchronizers/Format Converters, or the two channels can be linked with the internal FS2 keyer to do the work of three or more devices - for example HD sidebar keying where both the video and background graphics are up-converted and combined.

AJA hardware conversion technology

AJA's powerful hardware conversion technology ensures the highest image quality for your productions. Key conversion features include:

  • SD/HD up/down-conversion
  • SD/SD aspect ratio conversion
  • HD/HD cross-conversion (720p/1080i)
  • Up/down/cross-conversion with both the input and converted formats on SD/HD SDI outputs (both synchronized)
  • HD cross-conversion with simultaneous down-converted SDI output

FS2 can up or down-convert between SD, HD, and 3G HD (1080p50/60), and cross-convert between HD formats including 3G HD. Additionally, FS2 has full input and output signal routing, allowing any I/O port to be assigned to either processing channel.

Digital and Analog I/O

Capable of simultaneously working with two independent streams of 3G/HD/SD 10-bit broadcast-quality video and two independent groups of 16-channel AES audio, each FS2 video channel supports virtually any input or output: analog component or composite, 3G-SDI, Dual Link (1.485 Gb), Fiber and HDMI I/O.

For audio, FS2 has two audio processors, each supporting 16-channel AES/EBU digital audio, 16-channel embedded audio, and 8-channel balanced analog audio with a variety of controls for maximum flexibility. The output of each processor can be embedded in its respective video processor output (SDI, Fiber, or HDMI), or sent to the AES or balanced outputs. For 3G and Dual Link inputs, the audio processors can have access to all 32 channels.

Remote configuration and control

FS units are network ready and support SNMP monitoring and web-based remote control. Units can be connected to any Ethernet network via the built-in 10/100/1000MB Ethernet port, allowing control and configuration of multiple FS units from any web browser on a connected computer. Configurations can be saved and applied to multiple units, ensuring consistency and quick configuration in large installs.

To integrate smoothly with the existing automation of a facility, FS2 can also receive external GPI commands to trigger a variety of functions, from freezing an input source to switching between saved presets.

Fiber I/O option

FS2's Fiber I/O option allows fiber cable runs of up to 10 kilometers to be connected directly to the FS2 without the need for separate fiber to SDI conversion.

Fiber connector supported:

  • Single-channel LC connector modules
  • Single-channel SC connector modules
  • Dual-channel LC connector modules


FS2 is designed to meet the demands of broadcast engineering and live event production while providing incredible flexibility. Select any of the various inputs for conversion and route to all available outputs simultaneously.

Dual, redundant power supplies ensure uninterrupted power even in the event of a power supply failure.
