The pinnacle of audio performance, the ADA-8XR is a powerful yet extremely flexible multi-channel converter. It has been engineered and built for quality and embodies Prism Sound’s no-compromise approach to audio. The moment you power it up everything will impress; its construction, its sound quality, its flexibility, and its usability. 

The natural sound it delivers is effortless and the nearest to true analog you are ever likely to hear. If you need the absolute best in modular multi-channel conversion, the ADA-8XR is the only choice. 


The ADA-8XR offers accurate, ultra-detailed A/D and D/A conversion providing a complete focus of sound to ensure you’re not distracted by coloration while allowing every nuance of a performance to be heard.


Independent paths allow for different sample rates to be sent and received simultaneously.


The ADA-8XR is a modular system, which provides great flexibility when creating systems with larger numbers of channels. The modular design allows for the flexibility of having either an 8 input/8 output, 16 input, or 16 output converter with digital I/O cards for AES, Firewire, and Pro Tools|HDX also available. Whether you need just a few channels of high-quality conversion or large a multi-track setup, the ADA-8XR is a natural choice. Using combinations of the basic system options and the range of digital interfaces, you can build a system that perfectly matches your requirements.


The ADA-8XR is the audio industry’s converter of choice in the most exacting applications of music and sound recording, mastering, broadcast, and post-production. Offering the cleanest and most transparent conversion available, the ADA-8XR has found a home in some of the most iconic recording facilities worldwide. Ideal for producers, engineers, and songwriters wanting to produce the very best results when recording, tracking & overdubbing, mixing to stereo or surround, mastering, and monitoring. The ADA-8XR is perfect for recording vocal, single instruments, drums, or orchestras and is just as much at home providing multiple outputs for external analog summing. It is in use in the top studios around the world as well as being used in numerous film soundtracks.


The ADA-8XR takes the philosophy of the widely-acclaimed Prism Sound converter range a stage further: Now, the goals of ultimate sound quality, unbeatable performance, and unmatched versatility have been realized in a modular multi-channel, 24-bit 192kHz-capable format. The ADA-8XR provides A/D and D/A conversion and the essential digital interfaces with a stereo monitor mix output in digital and analog formats. 


Unlike most other converter systems, the ADA-8XR is ideal as a master clock for your entire system, whether running from its precision internal reference or from an external source. No external clock source can improve the performance or influence the sound of the ADA-8XR. In addition, the ADA-8XR can run in Pro Tools Loop Sync mode, or lock to AES3, AES11, or Word Clock. The ADA-8XR delivers your recordings with perfect transparency, whatever the setup.
