About: AJA FS1 Universal Frame Synchronizer/Converter.

FS1 is a powerful and flexible frame synchronizer and high quality converter that helps you work with mismatched signal types to establish a consistent format for post production or broadcast.

Flexible input, flexible output

Featuring a flexible input, output, and control architecture, the FS1 Universal HD/SD Audio/ Video Frame Synchronizer and Converter can simultaneously work with both HD and SD video all in full 10-bit broadcast quality video and 24-bit audio.

Supporting virtually any input or output, analog or digital, HD or SD, FS1 can up or down-convert between SD and HD, and provide simultaneous HD and SD outputs. Up, down, cross-conversion between HD formats are also supported, with simultaneous output of both formats.

AJA hardware conversion technology

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

  • 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

Digital and analog I/O flexibility

FS1 is loaded with comprehensive I/O that lets it handle the widest range of analog and digital signals - and convert between them.

Perfect for use in broadcast and post production environments, FS1 features Dual HD/SD-SDI inputs and outputs, comprehensive multi-channel audio connections and I/O for analog video equipment, including HD and SD component.

For audio, FS1 supports 8-channel AES, balanced analog, or 16-channel embedded audio with full flexibility and audio processing controls. You can choose from any of the 4 groups of embedded audio for 8-channel output on the AES or analog audio.

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, FS1 can also receive external GPI commands to trigger a variety of functions, such as freezing an input source.

Closed caption conversion

FS1 supports closed captioning and the conversion of closed captioning between SD and HD formats - including full conversion of CEA-608 captions to the CEA-708 standard. FS1 can preserve closed captioning even when converting between formats, removing the need to re-insert closed captions after conversion.

Active Format Description

Automatically sets Active Format Description information to match the converted signal. This means AFD information does not have to be inserted after conversion and provides accurate information for devices that understand AFD.


FS1 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 outputs simultaneously.

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

Extensive Connectivity

FS1 has a wide range of analog and digital inputs and outputs to allow integration into virtually any environment, featuring HD-SDI, analog component, composite and S-Video inputs and outputs and comprehensive embedded, digital and analog audio I/O with full routing capability. is a Canadian authorized AJA retailer.
