Prism Sound Lyra 1 USB Interface With Ultimate Collection

Prism Sound Lyra 1 USB Interface With Ultimate Collection

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 a single class-A microphone preamp, Lyra 1 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.

Software

Lyra’s hardware front panel gives continuous visual indication of the unit’s main settings and levels, but in-depth control is managed from the Lyra control panel. This runs on the host computer, and can be brought into view whenever adjustments are needed.

The upper area of the control panel shows a panel of ‘Global’ settings for the entire group of connected interfaces and a panel of ‘Unit’ settings which is assignable to each connected unit in turn, using the enclosed drop-list. These settings are concerned with general parameters such as sync source and sample rate selection, metering and buffering modes. An ‘Identify’ button causes all the LEDs on the selected box to light, to assist with identification in multi-unit systems. To the right, there are large buttons for loading and saving setups, and for on-line help.
