Hear what you've been missing If you're familiar with our older “blue” Pro Tools | HD interfaces, your ears are in for a major treat. Experience significantly better audio fidelity, wider dynamic range, and super-low jitter thanks to sophisticated A/D and D/A conversion. Capture and play back every audio detail. Retain the warmth and presence of your original sources. And get the lowest possible latency when recording even the largest sessions. Track with ease Connect your digital gear hassle-free with sample rate conversion in HD I/O’s digital configurations. Maximize your analog input signals, without any harsh clipping, with the soft clip feature. Plus, you'll be able to track hotter signals and smooth out inconsistent levels from incoming sources. Get I/O versatility The rack-mountable 2U HD I/O comes in three configurations, so you can choose the interface that best suits your connection needs. In addition, you can expand your analog or digital I/O by simply installing an HD I/O option card into any empty bay (see all configurations and options below). Gain full I/O control Like all Pro Tools | HD Series interfaces, HD I/O tightly integrates into any Pro Tools | HDX or HD Native workflow. That integration extends down into the software too, enabling you to gain complete control of your inputs, outputs, and routing right from the Pro Tools | Ultimate software interface. No matter how hard you push it, you can expect maximum performance and reliability every time.
