Differentiators	Get worry-free performance with all mixing, routing, automation, and processing handled by dedicated DSP Use the card to run AAX DSP plugins, freeing up CPU load Achieve the lowest latency in the industry Work with up to 768 voices per system—guaranteed Interface with any DigiLink-enabled hardware, supporting up to 192 channels of I/O Gain creative flexibility with support for both AAX DSP and AAX Native plugins Expand your system as your business grows	Leverage the power of your computer to handle all processing natively Interface with any DigiLink-enabled hardware, supporting up to 64 channels of I/O Achieve low latency while leveraging native CPU power
DSP processing	18 x 350 MHz TI processors per HDX card (6.3 GHz aggregated processing)	None (CPU host processing)
Latency*	0.7 ms	1.7 ms
Simultaneous voices/audio tracks	2,048 (HDX Hybrid Engine) 256 per card (HDX Classic)	2,048
Channels of I/O	64 (scalable up to 192 with three HDX cards)	64 (fixed I/O, not scalable)
Automatic Delay Compensation for hardware inserts	16,383 samples	16,383 samples
Processing depth	32-bit floating point	32-bit floating point

* Latency calculated using a 96 kHz sample rate with a 64-sample buffer. Tests run using Pro Tools \| HDX and Pro Tools \| HD Native with Pro Tools \| HD I/O, and Pro Tools \| HD Accel with 192 I/O.
** Audio tracks based on sample rates of 48/96/192 kHz, respectively. Installing additional cards will increase track counts to the maximum allowable.
