Standards compliant USB interface
Prism Sound has taken on board the increasing importance of native processing power for professional users and the fact that software products for standard PC and Mac platforms have been greatly enhanced in recent years.

Prism Sound is probably best known for A/D and D/A converters such as the venerable ADA-8XR and Orpheus, which already provides a solution for those needing a FireWire interface. However, the flexibility and versatility of the ADA-8XR comes with a higher price tag, reflecting the fact that no other interface provides such exceptional audio performance or can work directly into Pro Tools Core/Processing cards, as well as running a concurrent DSD processor or FireWire interface.

For Lyra, we have created a unit that is compatible with the widest range of computer hardware by using a USB2 interface. This is a UAC2 (USB Audio Class 2) interface supported natively in Mac, Linux and Android, and in Windows via a driver.

Lyra is easy to connect to your computer and to your outboard gear. For Windows users ASIO and WDM drivers are provided, while for Mac OS X 10.4 or later, Lyra interfaces directly to Core Audio. For both Mac and PC platforms, there is a controller application to configure the unit and control its built-in mixer and other functions. Aside from the monitor and headphone level controls, everything else is operated solely from the Lyra controller application. The controller software opens on-screen as a separate panel alongside your existing editing software. Since Lyra is UAC2 compliant, it will also work in recent Linux and Android builds, although no control panel is provided.

Looking to the future, low-latency synchronised networked audio and video is now becoming a reality with the implementation of AVB (Audio Video Bridging), an IEEE 802.1 networking standard. Lyra 2 is planned to support AVB in future firmware updates.
