The Lyra family of USB audio interfaces offers Prism Sound performance at its most affordable ever. They are based on the Orpheus audio path and clock circuitry, but in a smaller package for those who don't need eight channels of analogue I/O. There are two models Lyra 1 and Lyra 2. Lyra is based on an ARM Cortex processor design which offers class-compliant USB and the possibility for future Ethernet AVB interfacing, plus DSP and local mixing capacity beyond that of the present Orpheus platform.
