The Calyx Femto DAC heralds a new era in digital to analogue conversion, offering a new level of digital clock performance measured in femtoseconds (500 femtosecond accuracy) to reduce jitter to astonishingly low levels.
Built around twin Sabre ESS9018 DAC chips (8 converters per channel) and utilising dual power supplies, one for the digital circuits and one for the analogue output stage, the Femto DAC offers incredibly low THD (total harmonic distortion) level of 0.0003%, and extraordinary dynamic range measuring 130db.
The Femto DAC has been designed to be the centre piece of a modern digital music system, and as such can be used as a digital preamplifier feeding directly into your power amplifiers, or as a stand alone DAC. Inputs include two optical, two coaxial, two AES/EBU, one BNC and one USB input, all capable of 24bit/192kHz data rates.
The USB input is both USB 2.0 compliant and asynchronous in operation. Output is via gold plated unbalanced RCA outputs, or fully balanced XLR outputs. Like all Calyx products, construction is exemplary, with all aluminium billet construction with superb finishing.
The large display allows easy input selection from across the room via the included remote control, also milled from solid billet aluminium. Internally, the Femto DAC features an extremely high quality power supply encased in its own metal case within the chassis of the Femto DAC.
