Avid HDX Card

The HDX PCIe card from Avid provides unprecedented processing power and audio quality for Pro Tools. Musicians, recording engineers and post-production professionals now have access to the same technology used in world-class studios. The HDX card multiplies the voice capacity and DSP power of a single HD Accel card by up to 5 times. With up to 192 inputs and outputs and floating-point processing for mixing and plug-ins, the HDX card delivers superior sonic detail and nearly limitless creative potential.

Massive DSP Acceleration and I/O

The HDX PCIe card harnesses the power of 256 voices and a dedicated FPGA processor for the mix bus, freeing all onboard DSP for running plug-ins. The result is a level of power that can handle even the most complex productions with ease. HDX supports up to 64 inputs and outputs per card for a total of 192, providing ample connectivity for large studio setups and high-track count sessions.

Pristine Audio Quality

HDX uses 32-bit floating-point processing for plug-ins and mixing, producing audio with stunning depth, clarity and detail. The increased headroom prevents clipping and allows more subtle details to shine through. Combined with a Pro Tools HD Series interface, HDX delivers an unparalleled listening experience that brings out the best in any production.

Optimized Workflows

Tight integration between HDX, Pro Tools HD software and your computer results in highly responsive performance for recording, editing, mixing and more. Tools like real-time fades, RAM-cached playback, bus interrogation and Clip Gain streamline even the most complex workflows. For hands-on mixing, HDX pairs perfectly with Avid's control surfaces including the S3, S6 and Pro Mixing consoles.

Trusted Sound and Creative Potential

The HDX card provides the same renowned sound quality that has made Pro Tools the industry standard for audio production. With over 75 professional-grade plug-ins and virtual instruments included, plus compatibility with thousands more, HDX places a universe of creative options at your fingertips.
