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.
Signal path 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.
For low-latency foldback or monitoring to headphone or main outputs, each output pair (1-2, 3-4, digital out or the headphone output) can optionally be driven from the built-in DSP mixer with an individual local mix of any selection of inputs through the controller applet. All analogue inputs are electronically balanced with automatic unbalanced operation. Analogue outputs are electronically balanced with 'bootstrapping', i.e. level is maintained if one leg is grounded.
No-compromise, full Prism Sound audio quality 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. -
Lyra draws on Prism Sound's years of experience in developing digital audio products, including its range of audio test equipment, adopted by a wide variety of clients across the audio industry from pro-audio to consumer electronics. This experience means that Lyra is well-behaved both as a computer peripheral and an audio processor.
Reliability is vitally important in professional recording. Prism Sound has always made extensive use of precise software calibration techniques in its converters - pots and tweaks are always unreliable, so there are none.
The design team has gone to great lengths to minimise noise and interference, in particular hum. All of the analogue circuits have galvanic isolation, while the unit's electronically balanced I/O allows it to handle common mode interference sources as well as enabling trouble-free connection to unbalanced equipment.
It is often said that THD+N figures do not always correlate well with the perception of sound quality and this is true - partly because the traditional measures of THD+N or SINAD expressed as RMS figures are rather a broad measure. With this in mind, we have taken great care to make sure that not only is the RMS THD+N figure very good, but the Lyra noise and distortion spectrum is beyond reproach and that Lyra provides the most transparent listening experience.
Standards compliant USB 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
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.
Lyra is easy to connect to your computer and to your outboard gear. For Windows users ASIO is provided (WDM coming soon), 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.
Flexible Inputs and Outputs Our 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 Mixer Our customers also identified a need for a unit that could provide low latency foldback to performers, particularly when tracking and overdubbing. In answer to this need, Lyra 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 Shaping 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.
Unsurpassed Jitter Rejection In 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. 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.
