Normally ships 5-9 days

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).

Pro Tools | HD I/O—Premium, customizable Pro Tools | HD Series audio interface - 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.
