Keep your Pro Tools system and connected devices in sync—no matter how complex your setup. Pro Tools | Sync X serves as the backbone of modern audio post production, providing reliable low-jitter clocking and near sample-accurate lock with frame edge alignment. It’s a critical component for dubbing, ADR, Foley, and other precision workflows and a must-have in every room of your facility that requires audio sync to picture.
Leveraging the patented DigiSerial Port technology connection to Pro Tools | HDX or HD Native, Sync X enables precise sync between audio sample position and video frame edge. In multi-operator mixing environments, where dialogue, music, and sound effects are handled by separate systems, that means all of your audio and video devices will sync and play at precisely the exact same spot you intended. Every time you press play or record.
Sync up all your devices
With support for all industry-standard clock sources (including Word Clock, Loop Sync, and AES3), positional reference formats (including LTC, Serial Timecode, and Bi-Phase/Tach), SD and HD reference formats, and pull-up/pull-down rates for film and video, Sync X is an easy fit into any studio environment. Plus, six Word Clock outputs make syncing to Pro Tools interfaces and devices easy.
Cut costs with the built-in video reference generator
No need to rely on video reference from an external device. Sync X provides an onboard video reference generator with four outputs to distribute signals to other peripherals, cutting complexity and costs. If you already have an external video reference generator, Sync X can receive video reference too, with automatic format detection.
Streamline dual operator workflows
Sync X enables each Satellite-linked Pro Tools system to sync in tandem to support multi-operator mixing environments, where dialogue, music, and sound effects are handled by separate systems. This eliminates any possible drift to maintain near sample-accurate lock to frame edge.
Control Sync X and other devices from Pro Tools
From configuring your audio clock and video reference sources, to selecting pull down rates and fine-tuning device speeds, all Sync X settings can be controlled directly in Pro Tools | Ultimate. It also offers a 9-pin connection, enabling you to control other devices from Pro Tools, like a video deck.
Designed to shine in the most mission critical environments, Sync X consistently delivers the tight frame edge sync you need with unwavering accuracy. And its high-fidelity, low-jitter clock preserves the quality of your signals for pristine audio capture and playback.
Lock to sources fast and flawlessly
With exceptionally low jitter JetPLL clocking technology, Sync X locks to external sources faster and more accurately than its predecessor, Pro Tools | SYNC HD (compare Sync X vs. SYNC HD). Its master oscillator runs at 100 MHz—a double resolution implementation that’s twice as fast as typical JetPLL-based clocks. And twice as accurate.
Get flexibility with 10 MHz and AES3id I/O
When working on scoring stages and other demanding recording situations where immaculate sound is a mandate, Sync X easily locks to high-end atomic master clocks through its 10 MHz clock input. In environments that require long cable runs, such as across large post facilities, you can send or receive AES3 or AES3id signal to supported devices, giving you greater flexibility.
Keep cool when production gets hot
Temperature fluctuations can affect a device’s pitch. With a temperature-compensated oscillator, Sync X always provides reliable clocking—even as temperatures vary—maintaining frequency accuracy to within ±1 part per million over its rated temperature range to keep things pitch perfect. And it can be racked up with other gear without fear that the heat will cause it to drift.
Get peace of mind with minimal downtime
For those who operate on constant deadlines, Avid offers an Extended Hardware Support Plan that extends your 1-year hardware warranty to 3 years. Available for purchase within the first 90 days of registration in your Avid Account (get it now), it also provides zero-downtime advanced hardware replacement with overnight shipping, so you can keep working—not waiting on a repair.
