AVID 9900-60541-00 HD I/O Digital Option - Digital Input/Output Interface

Expand Digital Connectivity on Your Pro Tools HD I/O
The Avid Pro Tools HD I/O Digital Option Card is a professional-grade expansion module designed to enhance the digital input and output capacity of your existing HD I/O interface. By installing this card, users gain an additional 8 channels each of AES/EBU, TDIF, and ADAT digital I/O—providing greater flexibility for routing digital signals in both music production and post environments. It's a modular solution that allows audio professionals to adapt their HD I/O unit to the demands of increasingly complex studio setups.

Add More Digital I/O Without Replacing Your Interface
If your current HD I/O chassis is running short on digital connections, this expansion card offers an efficient way to add more without the cost of purchasing a new interface. Whether you need additional digital channels for integrating outboard gear, digital consoles, or other MADI-connected systems, this card makes it possible with minimal reconfiguration. It’s especially useful in hybrid studios where digital and analog workflows intersect.

Support for High Sample Rates and Protocols
The card supports AES/EBU up to 192 kHz in both single-wire and dual-wire formats, ensuring high-resolution compatibility with a wide range of professional equipment. ADAT support includes S/MUX II and IV, making it possible to transfer higher sample rate signals over multiple channels. This allows the card to remain compatible with modern converters and multichannel devices across various digital protocols.

Customizable Integration with Existing HD I/O Cards
Depending on the configuration of your current HD I/O chassis, this digital option card can either be added to available expansion slots or used to replace existing analog or digital cards. This flexibility enables users to tailor their system to meet specific studio needs—whether it’s expanding digital workflows, replacing legacy connections, or preparing a system for future upgrades.

Ideal for Hybrid and Digital-Only Environments
For studios that primarily rely on digital routing and processing, this card simplifies the connection process while maintaining signal integrity and reducing latency. It's ideal for situations where rack space is limited, and all-in-one digital patching is required. With just one card, you can connect multiple digital formats directly to your HD system and stay within Pro Tools’ powerful environment.

Simple Installation with Immediate Pro Tools Integration
The HD I/O Digital Option Card is designed to be installed directly into your Avid HD I/O chassis. Once mounted, it becomes immediately available in Pro Tools, with full routing and I/O configuration accessible via the software’s I/O Setup menu. No extra drivers or software are needed, ensuring seamless operation and time-efficient setup.
