hiFace Two
192kHz/24bit digital audio interface
REVISION 1.0 – MAY 2013
Dear customer,
thank you for purchasing hiFace Two. What you have is a first-rate USB-to-S/PDIF
converter with many unique features conceived to obtain the best audio performance out
of a music file.
Even if getting digital music out of a PC, a Mac or a Linux computer is nowadays quite
simple, much harder is to obtain the best sonic performance from it, due to intrinsic limits
in USB 1.1 audio standard and the implementation of digital audio interfaces in computers.
Please visit M2Tech website (www.m2tech.biz) to find extensive literature about this topic.
hiFace Two overcomes all the limits of usual USB-to-audio interfaces by exploiting the
powerful performance allowed by USB 2.0 Audio class and by using asynchronous data
transfer, along with a sophisticated electronic design.
hiFace Two is available with either RCA or true 75 Ohms output connector which suites
virtually all DAC’s and A/V receivers around.
We feel that your expectations will be fulfilled by hiFace Two: you’ll hear your DAC and
your music files in a way like never before, prepare for a whole new experience!
Nadia Marino, CEO

Figure 1
1) USB input. Connect directly to the USB 3.0 or 2.0 or 1.1* port of a PC, Mac or Linuxbased computer, or use an USB extender (A male to A female). In the latter, the extender
must be compliant with USB 2.0 and less than 3m, otherwise the bus performance will
decrease and the correct operation of the interface will not be guaranteed. USB type A
male connector
2) S/PDIF output. Connect to the DAC input with a 75 Ohms digital cable. RCA male
connector or BNC 75 Ohms male connector.
* hiFace Two performance on USB 1.1 are limited to 96kHz. Please note that 1.0 ports
won’t work.

2. Connection to the host
ADVICE: Windows users must install the driver prior to connecting the hiFace to the
PC (please refer to section 5).
Please refer to section 1, “Connections”.
Connect the hiFace Two to the host USB 2.0 port by inserting its USB plug (Figure 1, 1)
into the host socket. If straight insertion is difficult or when in need of avoiding straight
insertion, an USB 2.0 extender cable (A male to A female) can be used. Please avoid
using extenders more than 4m, to avoid invalidating the bus performance.
If your computer has a Windows operating system and a driver hasn’t been installed prior
connecting the hiFace Two, an error message may appear and you may need to
disconnect the hiFace Two and install the driver (see section 5.3).

3. True plug’n’play operation with Mac
Mac computers with OSX 10.6.4 and later have a native support for audio devices
compliant with USB Audio Class 2.0. This means that the driver is already included in the
operating system and the user needs not to install anything: just connect the hiFace Two
to your Mac and it will be immediately recognized by the OS and ready to use. Macs with
older OS need update to use the hiFace Two.
To use hiFace Two as output device for your Mac, you need to select it as default output
device from the Audio Control Panel (Preferences -> Sound) as shown in Figure 2:
Figure 2
After selecting hiFace Two, please check settings, particularly the output sampling
frequency (Figure 3): that setting forces the sampling frequency for the hiFace Two,
regardless the native sampling frequency of the various tracks being played back (to get
rid of such unease operation mode, you may want to use a player which automatically
changes this setting based on each track’s native sampling frequency, Like Sonic Studio’s
Amarra or PureMusic).

4. True plug’n’play operation with Linux
Linux has a native support for audio devices compliant with USB Audio Class 2.0 based on
ALSA. This means that the driver is already included in the operating system and the user
needs not to install anything: just connect the hiFace Two to your PC with Linux and it will
be immediately recognized by the OS and ready to use. ALSA version needs to be 1.0.24
or later.
To use hiFace Two as output device, select it as default output device for the system or
for the player you’re using.

5. Operation with iPad and Android-based tablets
iPad also supports USB Audio Class 2.0. This means that it is possible to connect the
hiFace Two to an iPad through the latter’s camera kit, which exports a high speed host
USB port. The limited supply current required by the hiFace Two makes it possible to
power it even by the reduced current capabilities provided by the iPad.
Once the hiFace Two is connected, the iPad automatically set it as default output device.
Android tablets may potentially use the hiFace Two, provided they have a 2.0 or 1.1 USB
host port capable of at least 100mA output current and ALSA or any other audio
management module compliant with USB Audio Class 2.0. Please refer to the tablet’s
specification chart.
