AVID 9935-71763-00 HDX PCIe Core Card with Pro Tools (Ultimate Software)

Real-Time DSP Audio Engine for Pro Tools Ultimate Systems
The Avid Pro Tools | HDX PCIe Core Card with Pro Tools | Ultimate Perpetual License is the high-performance backbone of professional Pro Tools environments. This package includes the HDX PCIe Core Card and a full perpetual license of Pro Tools | Ultimate, giving studios a reliable foundation for intensive music production and post workflows. The HDX card brings massive DSP power to the table, offering ultra-low latency processing, precise automation, and unmatched audio fidelity—all essential when working with large sessions or demanding client projects.

Hybrid Engine Workflows with DSP Acceleration
A standout feature of this system is the Hybrid Engine, which intelligently balances load between your computer's native CPU and the HDX card’s DSP cores. All session processing initially happens natively—ideal for flexibility and plug-in compatibility. But when low-latency monitoring is needed, tracks can be toggled into DSP Mode instantly, shifting the entire signal path and any DSP-ready plug-ins onto the HDX card. This ensures seamless recording with near-zero latency, while your CPU continues managing playback, virtual instruments, and native plug-ins without stress.

Massive Voice Count and I/O Expansion
Voice count capacity is a key metric for high-end audio systems, and this HDX system delivers. When using the Hybrid Engine, a single HDX card can handle up to 2048 simultaneous voices at all sample rates. Without the Hybrid Engine, the same card supports 256 voices at 48 kHz. With support for up to three HDX cards, users can scale their systems to 192 I/O channels and even more DSP plug-in power, making it a robust solution for expansive studio builds, broadcast environments, and post-production facilities.

Engineered for Ultra-Low Latency and Fast DSP Throughput
At the heart of the HDX PCIe card are 18 TI DSP processors and two advanced FPGAs. These components work in tandem to process signals in real time with extraordinary precision and speed. The primary FPGA handles PCIe interfacing and audio routing with latency as low as 0.7 milliseconds. The DSPs clock a combined 6.3 GHz for real-time plug-in processing, allowing you to record and mix with dense session loads, while keeping latency imperceptibly low.

Optimized for Precise Hardware Integration
With two DigiLink connectors and one DigiSerial port, the HDX PCIe card integrates seamlessly with Avid audio interfaces and sync peripherals. DigiLink supports up to 64 channels of I/O per card and enables Pro Tools to compensate for hardware insert latency automatically. The DigiSerial connector ensures sample-accurate synchronization with Avid SYNC HD or SYNC X peripherals, which is essential for audio-to-picture workflows in post-production environments.

Uncompromised Audio Precision and Performance Stability
Audio passes through the HDX system at 32-bit floating point resolution, preserving dynamic range and clarity from start to finish. A 64-bit floating point mixer ensures that all summing, automation, and internal processes maintain top-tier fidelity. With support for automatic delay compensation (up to 16,383 samples) and consistent signal integrity, the HDX Core Card is built for mission-critical reliability in commercial studios and demanding production settings.
