Get the absolute highest audio quality and unprecedented I/O flexibility with HD I/O, a high-performance Pro Tools® | HD Series audio interface that’s designed to completely integrate with Avid® Pro Tools | HD systems. While its sleek look resembles prior generation interfaces, HD I/O has been completely redesigned on the inside with high-quality electronics, giving you pristine A/D and D/A conversion, low latency, and maximum flexibility to integrate with a variety analog and digital gear.

Hear what you’ve been missing
A sonic improvement over its audio interface predecessors, HD I/O features premium A/D and D/A conversion, so you can achieve higher audio fidelity, extensive dynamic range, super-low jitter, and the absolute lowest possible latency in your sessions. With certain configurations, you also get built-in sample rate conversion and a soft clip feature for worry-free performance. And using Curv, a new built-in soft-knee limiter that catches even the fastest transients, you can track hotter signals and smooth out inconsistent levels from incoming sources.

The connections you need—now and later
HD I/O comes in three configurations, so you can choose the interface that best suits your connection needs. What’s more, you can expand your analog or digital I/O anytime by simply installing an HD I/O option card into any empty bay (HD I/O 16x16 Analog cannot be expanded, as all four bays are occupied).

The ultimate in interface flexibility
As your needs grow or change, you can easily add more analog inputs, analog outputs, or digital I/O by installing an option card.
• HD I/O AD Option: Adds 8 high-fidelity analog inputs (using DB25)
• HD I/O DA Option: Adds 8 high-fidelity analog outputs (using DB25)
• HD I/O Digital Option: Adds 8 channels each of AES/EBU (supports 192 kHz single-wire and dual-wire), TDIF, and ADAT (supports S/MUX II and IV) I/O

Work with Pro Tools and more
HD I/O and all other Pro Tools | HD Series interfaces completely integrate with Pro Tools | HD, so you get maximum performance, dependability, and control of your inputs, outputs, and routing right from your Pro Tools | HD Software interface. You’ll also get higher production quality and greater workflow flexibility than with previous Pro Tools interfaces. And if you want to use your interface and Pro Tools | HD hardware with other DAW software, you can do that too, as all Pro Tools | HD systems support Core Audio and ASIO drivers.

HD I/O 8x8x8
When you need a balance of analog and digital I/O, with the option for expansion, 8x8x8 is the perfect choice for music and audio post. It offers 8 channels of analog I/O, 8 channels of AES/EBU I/O, 8 channels of TDIF I/O, and 8 channels of ADAT (S/MUX) I/O. It also comes with 2 additional channels of AES/EBU I/O, 2 channels of S/PDIF I/O, and 8 additional channels of ADAT I/O. Plus, you can customize your I/O further with one empty bay for expansion play.
