Avid Pro Tools® | HDX Core (PCIe card) is the hardware engine extension of Pro Tools | Ultimate™ software, delivering the DSP power, scalability, and reliable performance that make the most demanding music and audio post-production workflows possible.

With HDX Core as the basis of your Pro Tools | Ultimate system, you’re set to add some I/O and weave your magic. Don’t forget, if you’re not using a Windows or Mac ‘tower’, you’ll need to house HDX Core in a Thunderbolt 3 Chassis (either desktop or rack version).

Talk with us when it’s time to jump in and pick the best I/O for your studio situation – including HD I/O and/or MTRX Studio and more.


Whether tracking a 5-piece band, full orchestra, or re-recording a theatrical Dolby Atmos® mix, you can scale the system’s DSP and physical I/O to any project requirement. Connect multiple Pro Tools hardware I/O interfaces to a single 64-channel HDX card. Install up to three HDX cards in a single system for more demanding projects, supporting up to 768 voices and 192 I/O channels while delivering smooth, uninterrupted performance.

Pro Tools | HDX is the industry’s most powerful DSP platform, providing 18 TI FPGA chips per card and 6.3 GHz aggregate processing, so you can handle the largest, most complex sessions with confidence. Record and mix thousands of tracks and plugins in real time. Monitor your system performance, so you always know if you have the headroom to add more AAX DSP plugins to your mix.
