Avid Pro Tools HDX Thunderbolt 3 MTRX Studio Rackmount System

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 768 voices. 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.
