Lyra represents the pinnacle of compact audio interfaces. Packing Prism Sounds trusted, uncompromising AD/DA conversion into a compact chassis perfect for use in the studio or on the road.
Based on the Orpheus’ audio path and clock circuitry, Lyra is ideal for those who don’t require a large I/O count, but do demand the highest quality and most transparent
AD/DA available.
