Avid Pro Tools | HD I/O Audio Interface

Get pristine sound quality and clarity for your most demanding recording sessions. Pro Tools | HD I/O is a high-performance audio interface designed for Pro Tools | HD systems that enables you to capture every detail and nuance of a performance. Achieve the high fidelity, extensive dynamic range, and lowest possible latency you need for large-scale, high-profile projects. Plus, its modular design makes it easy to expand and customize the interface for your connection needs—now and in the future. And with its new lower price, getting great sound is now even easier too.

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.

HD I/O 16x16 Analog
Get the maximum complement of analog inputs and outputs with the 16x16 Analog configuration—the ideal choice for music production. It offers 16 channels of analog I/O, 2 channels of AES/EBU I/O, 2 channels of S/PDIF I/O, and 8 channels of ADAT (S/MUX) I/O. While all four I/O bays are occupied with this option, you can swap out any of the analog cards with a different option card to customize.
