The Lyra 2 offers Prism Sound performance at its most affordable ever. It is 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.
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.
Analogue and digital input channels are available as inputs for your audio workstation software through the host computer's audio driver. Similarly, analogue and digital outputs and stereo headphone outputs can be played independently.
Lyra makes no compromises on audio quality. It is the result of years of research and development into digital audio conversion and extensive dialogue with Prism Sound's customers.
The Lyra design brief was: Prism Sound quality at an even more accessible price point. Lyra has the same no-compromise analogue front and back ends as its brother Orpheus, with the same fully-balanced-throughout architecture and the same isolation barriers protecting the analogue from digital and computer interference.
The digital output is equipped with the four Prism Sound SNS noise-shaping curves and includes Prism Sound's renowned synchronous sample-rate conversion (Lyra 2), allowing outputs to various external devices at other sampling rates. The sample-rate converter can be used at the outputs as well as the inputs, so as well as dealing with unsynchronised or wrong-rate digital inputs, Lyra can also generate, say, a live 44.1kHz output from a 96kHz session. Since Lyra also includes the full suite of the famous Prism Sound 'SNS' noise shapers, you can also reduce to 16-bits for CD at mastering-house quality. Lyra 1 supports sample rate conversion on the input only.
Prism Sound digital audio products lock up fast and re-generate ultra-stable clock outputs. Another aspect of the traditional Prism Sound converter that is retained was the clocking - it's just as important as analogue-path considerations sound-wise. Lyra uses the same CleverClox dual digital phase-locked loop (DPLL) circuitry as Orpheus so whether it's providing a high-quality master clock for the rest of the room (Lyra 2 only), or dealing with a jittery clock from outside, Lyra is as rock-steady as its forbears.
