Harrison USB/ADAT card for 500-series chassis

The Harrison D510ua is a high-performance USB and ADAT interface module designed for the D510 500 Series System, providing up to 26 inputs and 30 outputs across analogue and digital formats for professional hybrid workflows.

Overview

The D510ua transforms the D510r rack into a powerful audio interface, combining high-resolution conversion, flexible routing, and rock-solid connectivity. Each slot in the rack gains precision A/D and D/A converters, while the D510ua adds four additional D/A converters to feed the optional D510mx summing mixer card. It provides seamless integration with DAWs over USB while simultaneously supporting 16 channels of bi-directional ADAT I/O.

Connectivity and Conversion

Offering both USB and ADAT optical connections that can operate simultaneously, the D510ua lets engineers route analogue signals directly into the DAW while sending and receiving digital audio from external devices. It supports sample rates up to 192 kHz, ensuring transparent, low-noise conversion with the depth and accuracy expected from Harrison’s legendary console heritage. Word Clock I/O via BNC connectors maintains stable, jitter-free clocking in complex digital environments.

Workflow and Control

The intuitive front panel provides immediate source selection between USB and ADAT, along with independent input and output routing for flexible signal flow. Latency performance is exceptionally low—just 0.09 ms analogue to ADAT at 96 kHz, making it ideal for tracking and monitoring in real time. The D510ua delivers USB round-trip latency as low as 3 ms on Windows and 5.1 ms on macOS, ensuring precise timing for both recording and mixing.

Design and Integration

The D510ua draws power directly from the D510r rack, keeping cabling simple and installation clean. It’s class-compliant with macOS for plug-and-play operation and ships with dedicated ASIO/WDM drivers for Windows to ensure maximum stability. Built with Harrison’s renowned reliability, it performs equally well in the studio or on the road, handling demanding professional sessions with ease.
