Prism Sound Lyra-2 2 x 4 Small Format Audio Interface 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. RENOWNED AD/DA CONVERSION Lyra cuts no corners in its design and boasts the same trusted Prism Sound convertors used on countless hit records. It’s ultra-transparent characteristic means what you put into the Lyra is exactly what you get out of it. PRISTINE PRE-AMPLIFICATION Featuring two class-A microphone preamps, Lyra 2 guarantees superbly clean, detailed recordings that capture a performance the way it was intended. SOFT-CLIP LIMITING (OVERKILLER) Lyra's analogue input channels include a switchable Prism Sound 'Overkiller' circuit. This soft-clip limiter gently absorbs transients and allows signal levels to be pushed to their limits without risk. QUALITY SUPPORT Prism Sound's reputation for audio excellence has been matched only by its top quality after-sales support and technical advice. The longevity of a Prism Sound product is a testament to the dedicated team behind it.
