Flexible 4-Channel HD/SD or Single-Channel UHD 4K Processing

The AJA FS4 provides a versatile 4-channel frame synchronizer and converter that can process four independent HD/SD signals simultaneously or be configured to handle a single-channel UHD/4K workflow. This makes it perfect for a variety of professional environments, from broadcast studios to live event production, where multiple formats need to be synchronized and converted reliably.

12G-SDI Connectivity for Simplified 4K Workflows

The FS4 supports 12G-SDI, 6G-SDI, and quad-link 3G-SDI connections, making it ideal for handling 4K/UHD signals with fewer cables and simpler setups. The 12G-SDI interface allows for single-cable 4K workflows, greatly simplifying the infrastructure needed for high-bandwidth 4K video transmission. This is a major advantage for broadcast facilities and live event producers working with UHD content.

Up/Down/Cross-Conversion for Versatile Applications

The FS4 offers up/down/cross-conversion between a wide range of formats, including HD, SD, 2K, and 4K. Whether you're up-converting SD to 4K for broadcasting, down-converting UHD content to HD for web streaming, or cross-converting between formats for multi-camera setups, the FS4 ensures high-quality, frame-accurate conversions. It is particularly useful for productions that require simultaneous management of different video formats.

HDR Conversion and Processing

With support for HDR (High Dynamic Range) workflows, the FS4 allows for conversion between SDR and HDR formats. This capability is essential for modern broadcasts and productions that need to deliver content across a variety of platforms with consistent color and brightness levels. The FS4 helps ensure smooth transitions between different dynamic ranges, making it perfect for post-production and broadcast mastering.

Advanced Audio Capabilities

In addition to its video processing power, the FS4 features 16-channel embedded audio support and AES audio processing, allowing for sophisticated audio routing and synchronization. Whether managing multi-channel audio from SDI sources or embedding external audio, the FS4 ensures high-quality audio processing to match its video performance, making it suitable for live events and broadcast productions.

Frame Synchronization for Stable Output

The frame synchronization capability ensures that all video inputs are synchronized, eliminating jitter, signal drops, or mismatched frame rates. This is essential in multi-camera live production environments, where different video sources need to be perfectly aligned for seamless transitions. The FS4’s frame sync ensures clean switching between inputs, making it ideal for live broadcasting, OB trucks, and control rooms.

Closed Captioning and Timecode Support

The FS4 supports closed captioning pass-through and timecode management, ensuring compliance with broadcast standards and regulations. Timecode conversion capabilities allow for accurate synchronization between different video and audio sources, making the FS4 perfect for multi-camera productions or environments where precise timing is critical.

Redundant Power Supplies for Mission-Critical Operations

Designed for mission-critical applications, the FS4 features dual redundant power supplies, ensuring continuous operation even in the event of a power failure. This redundancy is essential for live broadcasts, sporting events, and other high-stakes environments where downtime is not an option.

Remote Control and Automation

The web-based interface allows for remote control and configuration of the FS4, giving operators the ability to manage and adjust settings from anywhere with network access. Additionally, the FS4 supports GPI automation, enabling operators to automate specific tasks during live events or production workflows.

Compact 1RU Design for Professional Integration

Housed in a 1RU rack-mountable chassis, the FS4 integrates easily into broadcast racks, mobile production units, or post-production suites. Despite its compact size, the FS4 delivers high-end performance with support for multi-channel video processing, making it a powerful and space-efficient tool for professional production setups.

Ideal Use Cases

The AJA FS4 is ideal for broadcast engineers, live event producers, post-production teams, and AV professionals who need a reliable, multi-format solution for 4K/UHD and HD/SD signal synchronization and conversion. With its 4-channel HD/SD support, 12G-SDI connectivity, and HDR processing capabilities, the FS4 excels in multi-camera live productions, broadcast environments, and UHD post-production workflows.
