German of audio interface manufacturer RME has announced SteadyClock FS, the latest version of its SteadyClock technology that offers synchronisation and jitter suppression in digital audio signals.
This ultra-stable femtosecond clock reduces self-jitter by improving its second, analogue PLL circuit and referencing both Direct Digital Synthesis and PLL to a low-phase noise quartz crystal. ‘SteadyClock FS provides the lowest jitter possible,’ claims Synthax (US distributor) Director of Sales, Americas, Derek Badala. ‘The clock performance in our interfaces enables end-users to optimise recordings and mixes because the soundstage has more depth and clarity.’
SteadyClock was originally developed to gain a stable and clean clock from the heavily jittery Madi data signal. Self-jitter is measured through DA conversion and now reaches levels that are usually only available in master quartz clock mode, while Steady Clock continues to run in PLL mode. Despite if it’s an internal or external clock, the sound is exactly the same. The low phase noise oscillator driving the updated circuit reaches jitter specs lower than a picosecond (femtosecond accuracy).
SteadyClock FS features a few small improvements in the latest FS version, including more efficient filtering and a design based on a super low jitter reference clock.
RME’s recently released ADI-2 DAC converter is the first product in the RME family to feature SteadyClock FS. The ADI-2 DAC is a versatile 2-input/4-output studio-quality ADDA converter that can be used as a USB audio interface, a double headphone amplifier, a high-end ADDA frontend and headphone amp for iOS devices, a multi-format converter (AES, SPDIF, ADAT) with monitoring function, a DSD record and playback solution, and an AD/DA frontend for audio measurement up to 768kHz sample rate. The new SteadyClock FS technology provides the ADI-2 Pro FS with ultra-stability.
