From Avid
Power to push limits.
In recording studios and on soundstages, Pro Tools | HDX Systems make the world’s biggest productions possible. Engineered for the highest performance, customization, and expansion, they enable music and audio post professionals to deliver their most demanding work. Without constraint.
HDX ENGINE
Uncompromising performance.
Pro Tools | Ultimate is the platform. The HDX hardware accelerator is the engine. And it is built to perform. 18 DSP processing cores. Up to 2,048 voices with the Hybrid Engine. Up to 192 I/O channels. 0.7 ms latency. From recording the biggest bands to mixing Dolby Atmos, against the tightest timelines, this is the power to remove barriers so you can create your greatest work.
The HDX PCIe card. Finely tuned.
With 18 DSP cores and two high-performance FPGA chips, the Pro Tools | HDX PCIe card is a powerhouse. And it’s finely tuned to process thousands of audio streams at staggering speeds. The central FPGA rapidly routes signal around the card—one sample at a time—with no latency. While the DSPs handle mixer and real-time plugin processing at an amazing 6.3 GHz aggregate clip. The result? Dedicated horsepower to mix the biggest sessions. And immense performance to record directly into them—with real-time effects.
Capability you can count on.
The HDX Engine matches its phenomenal performance with rock-solid reliability. A second FPGA guarantees 256 voices per PCIe card. And it streams audio to and from your host CPU at uniform 32-bit float precision, preserving the highest possible audio quality throughout the system’s gain structure. So when the work is mission critical and you press record, you’re backed by exceptional, unwavering capability. You can depend on it.
Power. Plus more power.
HDX Systems support up to three PCIe cards, so you can meet the scope of any project. Record orchestras. Mix immersive audio. And expand to the extremes with access to 2,048 voices with the Hybrid Engine. It’s extraordinary, scalable capability to make the most demanding music and audio post productions possible.
DigiLink and DigiSerial. High-performance ports.
The HDX PCIe card connects to Pro Tools hardware over uniquely designed connectivity formats. Two DigiLink ports provide 64 channels of I/O and ensure the highest fidelity audio in and out of the HDX Engine. DigiLink also allows Pro Tools to automatically compensate for hardware insert delays. While the DigiSerial Port is part of a patented technology, providing unmatched sample-accurate synchronization of video frame edges with audio.
