Orpheus One Digital-to-Analogue Converter - DAC
Orpheus One is a state of the art digital-to-analogue converter based on specially developed innovative, proprietary upsampling and conversion technologies.
A convenient phase inverter (0°, 180°) allows the user to compensate for phase inversion elsewhere in the system or in the recording itself.
To fully realize the potential of CD audio, upsampling is executed with a unique algorithm based on quantum mechanics. Unlike traditional re-sampling techniques, where new intermediate values are interpolated based on adjacent signal values, Orpheus generates a more accurate analogue output based on function coefficients derived from multiple preceding values.
Orpheus One employs an innovative Master Clock placed close to the DAC for significantly reduced intermodulation and totally isolated re-clocking unaffected by external interference. The isolated clock reduces jitter for improved stereo imaging and more precise localisation, as well as greatly enhanced speed and attack.
Incoming and outgoing data streams are completely separated for more effective signal processing. Local regulation of the various processing stages reduces interference and potential disruption for signal quality that sets new standards for the CD medium.
Modular expansion
The Orpheus One can accommodate two additional processing boards. Mount one
or two Orpheus DA-One 24-bit/192 kHz DAC boards in these slots to create a powerful
multi-channel digital to analogue conversion engine. The upsampling module or
the entire conversion board can be upgraded in the future as technologies evolve.
The blue dot-matrix display features large characters to ensure increased readability
and an input naming function that allows the owner to customize names up to
ten characters long for each source component.
The display has five user-selectable levels of illumination from full brightness to OFF.
In Night Mode, the display can be programmed to illuminate briefly to acknowledge reception of a command whenever a button on the front panel or remote is pressed before turning off again.
In conjunction with the front panel display, Orpheus’ specially developed menu navigation system becomes an ingenious communications centre for efficient, intuitive control with minimal fuss.
Designed to fit a single rack unit (482 x 370 x 44 mm), each Orpheus component employs an ultra-compact signal path layout for significant gains in audio performance.
In keeping with Orpheus’ subtle styling, the basic black chassis and natural brushed aluminium front panel lend a sense of timeless, understated elegance to any contemporary home interior. Their modest dimensions make it easy for the proud owner to choose uncompromising High End performance and uncompromising style.
