AVID 9900-74104-03 Sync X Synchronizer and Master Clock for Audio

Synchronize Pro Tools and External Devices with Precision
The Avid Pro Tools | Sync X is a professional-grade synchronization interface that ensures rock-solid timing between your Pro Tools | HDX or HD Native system and any external video or audio device. Built for audio post-production environments that require frame-accurate alignment, Sync X delivers low-jitter clocking and maintains near sample-accurate synchronization, whether you're working on ADR, Foley, dubbing, or full-scale film scoring. It’s the solution trusted by post facilities that can’t afford drifting clocks or timing errors.

Achieve Perfect Frame Edge Lock with DigiSerial Technology
Sync X utilizes Avid’s proprietary DigiSerial Port technology to maintain accurate sync between Pro Tools sessions and external video playback devices. This enables perfect alignment of the audio sample position to the video frame edge—critical when multiple engineers are working simultaneously on dialogue, sound effects, and music stems. Whether you’re mixing a commercial or an entire feature film, this level of precision ensures everything stays exactly where it’s supposed to.

Support for All Major Clock and Reference Formats
With support for Word Clock, AES3, Loop Sync, LTC, Serial Timecode, Bi-Phase/Tach, and a wide range of SD and HD video references, Sync X fits seamlessly into any professional post-production workflow. It also offers six Word Clock outputs to easily feed multiple devices in your studio. For film and television work, pull-up and pull-down rate compatibility ensures smooth operation across different playback formats and delivery specs.

Built-In Video Reference Generator for Simplified Studio Design
Sync X eliminates the need for a separate video reference generator by offering four video ref outputs directly on the unit. These outputs allow signal distribution to other devices without requiring additional hardware. Sync X can also receive and automatically detect external video reference signals, providing flexibility without complicating your setup or increasing your equipment costs.

Designed for Multi-Operator Post Workflows
In dual-operator environments, Sync X enables multiple Satellite-linked Pro Tools systems to stay perfectly synchronized without drift. Each station—whether managing dialogue, music, or effects—locks to the same reference, allowing collaborative workflows to operate as one coherent unit. This functionality is essential in modern post facilities handling multichannel audio and large-format video simultaneously.

Full Integration with Pro Tools and External Control
Sync X settings can be managed directly inside Pro Tools | Ultimate, giving users full control over clock sources, reference inputs, and pull-down configurations. A built-in 9-pin port also provides external device control, enabling Pro Tools to operate video decks or other machines through standard protocols. This makes Sync X not just a timing interface—but a central hub for your entire post-production rig.

Superior Clocking and Flexible I/O for Demanding Environments
Equipped with JetPLL technology and a 100 MHz master oscillator, Sync X offers exceptional stability and faster lock times than previous generation units. For complex scoring stages, its 10 MHz input supports locking to atomic master clocks, while AES3id I/O ensures clean signal transmission across longer cable runs. With temperature-compensated components and precision clocking, Sync X maintains frequency accuracy in variable environments.
