hiFace Hi-End S/PDIF Output Interface
DETAILS 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. FEATURES 1) 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). 2) 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. 3) 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. SPECIFICATIONS Connections Input 1 x USB A type male Output 1 x

hiFace Evo
Hi-End S/PDIF Output Interface DETAILS hiFace Evo by M2Tech is the new statement
in high quality computer audio interfaces. Hosted in a compact and stylish
aluminium case, hiFace Evo is capable of flawlessly transfer audio data up to
192kHz, 24 bits to virtually every DAC or A/V receiver around, thanks to its
comprehensive outputs set. hiFace Evo incorporates the same leading edge
technology as the classic hiFace – with some plus. Asynchronous operation up to
192kHz is used in conjunction with proprietary drivers which allow for Kernel
Streaming, Direct Sound and WASAPI operation (the latter under Windows vista and
7). Windows and Mac drivers are already available. Very high precision, very low
phase noise (jitter) crystal oscillators are used. To further improve their
performance, they have a dedicated shunt voltage regulator which ensures a very
low noise and spurious-free supply. hiFace Evo is powered by an external power
supply (not included), to avoid the dirty USB bus supply from negatively
affecting hiFace Evo’s performance. Linear regulators are used all around, to
allow all jitter-sensitive digital circuits to operate at their best. Also, a
low-pass filter is provided at supply input to further reduce any bad influence
from the supply. hiFace Evo can be powered by an external wall adapter (9V 1A
will fit), or with a 9V alkaline battery, or with a 7.2V/10.8V Lythium battery.
Several outputs are available at the same time: coax on RCA, coax on true 75
Ohms BNC, AES/EBU on male XLR, optical on Toslink™ (Toslink™ is guaranteed to
operate up to 96kHz, though we got operation up to 176.4kHz on certain setups),
optical on ST (for high-speed operation up to 192kHz and up to 1.6km or 1 mile),
straight I2S for direct connection to DIY DACs on RJ-45 (NOT plug-in compatible
with NorthStar products!). All outputs, except straight I2S, are galvanically
isolated (coax and AES/EBU via a pulse transformer). AES/EBU output can be set
to professional or consumer mode by an internal jumper. In addition, an input
for an external clock is available, for those who have a extremely precise and
stable clock generator to be used with hiFace Evo. hiFace evo automatically
recognizes the presence of the clock on its input and switches on it whenever
available. This input is also galvanically isolated via a pulse transformer.
Three LEDs indicate power, external clock presence and incoming data from the
PC. Connection to the PC is via a type B female USB connector. FEATURES 1)

Evo Supply High Performance Power Supply
DETAILS Evo Supply is a battery-based high performance power supply. It’s the
perfect companion to the hiFace Evo and other 9V-operated M2Tech devices. Evo
Supply features a Li-Ion battery with 2200mAh capacity (minimum), an integrated
battery charger and a low-noise regulator which is used to provide current to
the load while the battery is being charged, thus ensuring continuous operation
to the load. Charge time is about three hours, the best choice to ensure a long
battery life. Evo Supply delivers up to 1A (peak) on 9V (low-noise
regulator) or on 9.5V to 11V (battery). Two outputs are available for more
versatility. A switch allows for turning the load off when not used to save on
battery charge. Another switch allows to select the operation mode: automatic
charge or charge inhibit. Two leds indicate the presence of the wall adaptor and
the charge in progress. In automatic charge mode the battery charger starts
charging the battery every time the battery voltage drops below a low threshold.
During the charge, the low-noise regulator feeds current to the load. At the end
of the charge process, the output reverts to the battery. In charge inhibit
mode, the battery is used down to the low threshold and then the load is
disconnected to avoid excessive depletion. Charge is then started by switching
to automatic charge mode. The battery is protected against overcharge,
overcurrent and excessive depletion. A 15V/2A detachable wall adaptor provides
current for battery charging and load powering when the battery is being charged.
The user may disconnect the wall adaptor after battery is fully charged in order
to reduce interferences to a minimum. Evo Supply features heavy duty
output connectors for reliable contacts Two cables terminated with 5.5/2.1mm
plug (positive on tip) and a universal power wall adaptors are included in the
package. FEATURES 1) LONG BATTERY DURATION: around 7 hours when powering
the hiFace Evo. 2) VERY LOW NOISE even when using the internal regulator.
3) STYLISH ALUMINUM CASE matches the look of the hiFace Evo.
SPECIFICATIONS Size: 105x46x104mm (w x h x d, case) 105x50x150mm (w x h x d,
