Prism Sound Lyra 1 USB Audio Interface Overview: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. Signal pathAnalogue 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. No-compromise, full Prism Sound audio qualityLyra 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. Standards compliant USB interfaceFor 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. Flexible Inputs and OutputsOur professional users wanted a highly integrated solution with stereo inputs serving as line, instrument or microphone inputs, and line outputs that could be used for stereo monitoring, mastering and/or foldback to performers. Lyra offers up to four monitoring outputs, digital inputs and outputs as stereo AES3 or S/PDIF or up to 8 channels of digital I/O on the ADAT optical format, plus stereo headphones. Digital MixerLyra has a built-in digital mixer that can be configured from the host computer to provide foldback feeds to performers, each with their own stereo mix of workstation playback and any of the inputs. Sample Rate Conversion and Noise ShapingLyra 1 supports sample rate conversion on the input only. Unsurpassed Jitter RejectionIn the 1990s Prism Sound pioneered testing of sampling and interface jitter and as a result our digital audio products deliver unsurpassed jitter rejection. 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. Features:
