<h3>Hear what you’ve been missing</h3>
<div>
	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 recording. 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.
	<br /><br />
	<h3>Comprehensive connectivity</h3>
	So you can choose the interface that best suits your connection needs, Avid HD I/O comes in three configurations: 
	<a href="https://www.rspeaudio.com/Avid-Pro-Tools-HD-IO-16x16-Digital-p/avid-hd-io-16x16-digital.htm"><b>16x16 Digital</b></a>, 
	<a href="https://www.rspeaudio.com/Avid-HD-IO-8x8x8-p/avid-hd-io-8x8x8.htm"><b>8x8x8 Analog/Digital</b></a>, and <a href="https://www.rspeaudio.com/Avid-HD-IO-16x16-Analog-p/avid-hd-io-16x16-analog.htm"><b>16x16 Analog</b></a>. All HD I/O interfaces come with two channels of AES3 digital I/O on XLR, eight channels of ADAT I/O with S/Mux II & IV support) 2-channel S/PDIF on RCA connectors, word clock I/O, Loop Sync I/O and a mini expansion port add other HD I/O systems.  What's more, you can expand your analog or digital I/O by simply installing an HD I/O option card—that’s right, all that connectivity and still there’s room for more.

	<h3>Avid Pro Tools HD I/O 16x16 Digital configuration:</h3>
	<b>
	Versatile digital I/O:
	</b>
	<ul>
		<li>16 channels of AES3 I/O (supports 192 kHz single-wire and dual-wire) </li>
		<li>16 channels of TDIF I/O </li>
		<li>16 channels of ADAT I/O (supports S/MUX II and IV) </li>
	</ul>
	<b>
	Additional digital I/O:
	</b>
	<ul>
		<li>2 channels of AES/EBU I/O (supports 192 kHz singlewire) </li>
		<li>2 channels of S/PDIF I/O </li>
		<li>8 channels of ADAT I/O (supports S/MUX II and IV) </li>
		<li>Two empty bays for I/O expansion </li>
	</ul>
	<b>
	The ultimate in interface flexibility</b><br />
	HD I/O option cards add more analog inputs, analog outputs, or digital I/O. As your needs grow or change, you can easily add more analog inputs, analog outputs, or digital I/O by installing an option card. While HD I/O 16x16 Analog comes with the maximum four cards, you can customize your I/O by swapping out any card.
	<ul>
		<li>HD I/O AD Option: Adds 8 high-fidelity analog inputs (using DB25)</li>
		<li>HD I/O DA Option: Adds 8 high-fidelity analog outputs (using DB25) </li>
		<li>HD I/O Digital Option: Adds 8 channels each of AES/EBU (supports 192 kHz single-wire and dualwire), TDIF, and ADAT I/O (supports S/MUX II and IV) </li>
	</ul>
	<br />
	<h3>Work with Pro Tools and more</h3>
	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 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 with Pro Tools| HD and other DAW software, you can do that too, as all Pro Tools|HD systems support Core Audio and ASIO drivers.
