Avid Pro Tools | HDX Core
Pro Tools | HDX is Avid's DSP acceleration card for Pro Tools Ultimate. Each PCIe card carries 18 DSP processors at 350 MHz, 6.3 GHz aggregated, plus two FPGAs, and runs real-time AAX DSP plugins and the mixer with 0.7 ms latency at 96 kHz and a 64-sample buffer. One card gives 256 voices at 48 kHz, and the Hybrid Engine raises that to 2,048 voices at all sample rates.
Two DigiLink ports carry 64 channels of I/O to Pro Tools interfaces such as MTRX II and MTRX Studio, and the DigiSerial port links Sync X for frame-edge sync. Up to three cards fit in one system for 192 channels of I/O. It installs in a PCIe slot or in the HDX Thunderbolt 3 chassis, and needs Pro Tools Ultimate.
