Highest quality digital audio up to 192kHz/24bit S/PDIF audio format available from your PC or MAC Very low jitter oscillators and proprietary drivers Compact size (2x2.2x10.2cm) with hi-end performances hiFace USB interface has been conceived to obtain the highest quality digital audio signal using a PC or MAC. hiFace input format is a data stream signal with sampling frequency/resolution up to 192kHz/24bits, available from a PC or MAC USB port. A very high quality S/PDIF stereo audio output signal is available from hiFace for your Hi-Fi system DAC (Digital to Analog Converter). HiFace looks like a small USB pendrive, featuring a very compact size. Internal very low jitter oscillators and proprietary drivers allow for playing 192kHz/24bits audio files that feature the best signal quality.
- LOW JITTER, LOW PHASE NOISE, HIGH STABILITY OSCILLATORS
Most audio interfaces and USB-provided DACs refer the data stream clock to the same USB interface clock, that often suffers a very heavy jitter (short range oscillator frequency variations). Thanks to two quartz precision oscillators used on M2Tech hiFace, clock source for output data stream features a very low jitter. A more stable clock is recovered by DAC S/PDIF receiver; a low jitter produces a very limited sound image distortion and degradation. Phase noise (main responsible for jitter) is also very low: this guarantees a short and long range clock stability, also reinforced by a board supply voltage regulation (e.g. at environmental temperature stability is 2-5ppm approximately, compared to 50-100ppm performed by oscillators normally used on commercial CD players).
- PROPRIETARY DRIVERS
The standard audio drivers available on the market (e.g. Microsoft Windows operating system) dictated constraints can be overcome thanks to hiFace proprietary drivers: they allow for transferring audio data, maintaining the original file quality without any loss of resolution quality; also, sampling frequency constraints are overcome, while Microsoft and ASIO drivers oblige to operate at no more than 96kHz. When hiFace is used together with a player application such as FooBar (available for free on Internet), you can transfer S/PDIF stream music files to a D/A converter at 192kHz/24bits maximum frequency/resolution, avoiding undesired PC or MAC audio mixer data processing during the data transfer from hard disk to interface. Presently, Windows XP, Vista, Windows 7 drivers are available, as well as Mac drivers for 10.4, 10.5 and 10.6.
- COMPACT SIZE AND EASE OF USE
M2Tech hiFace features a very compact size and can be directly (or using an accessory USB A-A adapter, not supplied with hiFace) connected to a High Speed USB 2.0 port of any computer. A very high electric and mechanical performance RCA gold connector provides an output signal, ready to be connected to a Hi-End system. No external power supply is required, as hiFace draws its power from USB bus itself and regulates it with its internal regulators. hiFace USB interface connected to a last generation mini PC provided with a High Speed USB port makes for a complete music transport system at very low prices (in the range of few hundreds Euros). Such system allows for listening any density and resolution music files, playing own CD's using a CD ROM drive, obtaining access to more than 10,000 web radio, many of which broadcast their transmissions with CD quality.
