using its included Control Panel. The Windows mixer is disabled to prevent it from
adversely affecting the signal quality.
Which operating system?
The UF400e can only be used under Mac OS 10.3.4 (OS X) or higher. It can be
integrated easily using OS X CoreAudio and CoreMIDI.
UF400e Firewire Audio Expansion Board Users Manual

12
Installing the UF400e driver in OS X
As mentioned above, the UF400e uses the operating system’s CoreAudio and
CoreMIDI drivers. It’s therefore not necessary to install a device-speci c driver.
Simply plug the device into your FireWire™ port and it’s available immediately.
However, to take full advantage of advanced routing, samplerate switching and other
features, please install the included Control Panel. Simply run the installer in the
Driver & Control Panel\MAC folder.
The UF400e as a system audio device (Mac OS X)
If you would like to use the UF400e not only for speci c audio applications, but as
your default Mac OS X audio device, select the UF400e audio driver in the “Sound”
control panel as the default device for audio output.
UF400e Firewire Audio Expansion Board Users Manual

The FireWire™ port
FireWire™ is a serial PC interface similar to USB that was developed by Apple in 1995,
and which was originally intended for digital video data and for external mass storage
and audio devices. It has since been given many names that all refer to the same port: for
example, Sony calls FireWire™ “i.LINK?”, Texas Instruments refers to it as “Lynx?”,
and one also frequently sees the mysterious abbreviation “1394”. The latter designation
actually refers to the common IEEE 1394 standard, which is notable for its high data
rates (IEEE 1394a = 400 Mbps and IEEE 1394b = 800, 1600 and 3200 Mbps). (For
those of you who are sticklers for detail, IEEE stands for the US “Institute of Electrical
and Electronic Engineers”.)
Like USB, FireWire™ also supports hot plugging—in other words, you do not need to
shut down your computer to add or remove devices. However, you should take care not
to interrupt any applications that may be accessing the UF400e to prevent possible data
losses or blue screens. Also please note that it may take the operating system a while to
process the new situation—after all, machines are only human :-)
One standardtwo sockets
The socket on your PC can have two different forms, with either 4 or 6 conductors.
According to the standard, in the 6-pin version the two extra pins are used to supply
7.5 – 30V / 1.5A per port. Unfortunately, this is often not the case due to the poor
quality of some controllers that are unable to provide a constant operating voltage
—despite the requirements of the speci cation. So if you’d like to avoid any
unexpected failures of the UF400e, please use the D.C. or USB port on UF keyboard
to supply power—better safe than sorry. If your computer “only” has a 4-pin port,
you must use the D.C. or USB port. To connect the UF400e to your PC in this case,
please use the adapter (6-pin to 4-pin).

The connections of the UF400e Firewire
Audio Expansion Board
The UF400e offers you numerous connections for connecting professional studio
peripherals and HiFi devices. Following is a detailed overview of its technical and
electrical characteristics:
UF400e panel
MIDI IN S.W.
MIDI IN S.W. is a key to switch the original MIDI signal. The signal comes from
UF keyboard when the key locates on KB. The signal comes from UF400e when the
key locates on 1394.
Analog outputs
Panel (Out L/R)
The UF400e features two high-quality analog mono outputs on its panel. The
connections have been realized as balanced 1/4” jacks. Unbalanced cables can also
be plugged into the outputs, of course.
Panel (Out Phone 1/2)
Two further analog output (stereo) is available on the panel that can be used either
at Line level (2.0 Vrms) or as a hardware-controlled headphone output (with an
adjustable level). The mode for this output can be selected in the Control Panel.
On the driver side
all of the outputs are grouped in a multi-channel device. The relevant driver is
UF400e Firewire Audio Expansion Board Users Manual
The analog outputs operate with music-compatible levels of 2.0
Vrms. Here, you can connect a mixing Board, active speakers, or
ampli ers.
CAUTION!
As the UF400e can deliver an output of up to 2.0
Vrms in Line mode and even more in headphone mode, a very
high (loud) level will be available depending on the impedance of
your headphones. Take care of your ears, you only have one pair!

15
called “UF400e(0) MC Out”. The channels can be addressed individually using
common audio applications.
Analog inputs
In L/R
The UF400e System features two high-quality analog stereo inputs on its panel,
which are named “LINE IN L/R” and “MIC/GT IN”. The connections have been
realized as unbalanced stereo 1/4” jacks. Unbalanced mono sources can also be
plugged into the outputs, of course.
There is only one connection can be used at same time. The “LINE IN L/R” will
be disabled as long as guitar or microphone hooks up “MIC/GT IN”. In the mean
time UF400e receives the signal comes from “MIC/GT IN” only. It has to keep “
MIC/GT IN” un-plugged if you want to record signal from “LINE IN L/R”. The “
LINE IN L/R” can only recognize line level signal.
It can be chosen between MIC and Guitar by the control panel of Analog In.
Three different gain levels can be set in the Control Panel via high-quality relays:
Guitar
:
maximum level at 0.5 Vrms input level
Mic
:
maximum level at 1.3 Vrms input level
On the driver side
The inputs are viewed as a stereo pair (1+2). The driver is called “UF400e(0) In 1”
Practical tip:
Make full use of the 24-bit support of up-to-date
software applications and connected digital peripherals—even if
you are planning to “just” release your production on CD. The
admittedly subtle increase in audio quality pays off noticeably in
the total signal and especially in digital editing.
Practical tip:
While recording, try to achieve as high a recording
level as possible to get the greatest bene t from the wide dynamic
range of the 24-bit converter. Always remember that a clean take
is far more valuable than the best corrective plugin.
. Both channels can be used in mono mode in most audio editors.
UF400e Firewire Audio Expansion Board Users Manual

16
Digital interface (S/PDIF)
Use the digital interface of your UF400e Board to transfer music digitally from your
computer to other devices, or to record audio data with your computer. There are two
separate coaxial jacks (cinch) for recording and playback. The interface can send and
receive sample rates of up to 24-bit / 96 kHz. The recording driver is called “UF400e
(0) SPDIF In”, and the routing must be set to the digital output in the Control Panel
for playback.
Synchronization.
When recording from a digital source, make sure that the
sampling rates of both devices (e.g. DAT recorder and laptop) are synchronized.
The S/PDIF protocol contains a signal for this purpose. If such a signal is
applied to the digital input and the Master Clock switch is set to “External”, the
UF400e will automatically synchronize to it and the “Digital In” channel will be
available in the mixer.
ASIO applications such as Cubase SX often have an option to switch the
hardware from an internal to an external (sometimes also called S/PDIF) clock
source. This changeover currently has no effect on the UF400e. The switch to
an external clock is not to be confused with external synchronization to MIDI
devices, video equipment or tape decks and therefore cannot be found in the
Sync, MIDI Clock, MTC or SMPTE settings of the applications.
AC3
and
DTS
can also be played back via the digital output. Select “NonAudio
DTS can also be played back via the digital output. Select “NonAudioDTS
” for the digital output in the Control Panel under “Routing”. This setting mutes
the Digital Play path in the digital mixer so that the non-audio signals are not
also sent to the analog outputs.
MIDI interface
MIDI IN/OUT/THRU is available for suitably-equipped peripherals such as MIDI
keyboards, DAW controllers and other devices. The cables for MIDI connections are
Practical tip:
For an absolutely clean and jitter-free signal path
(when mastering, for example), use special shielded RCA cables
to transfer digital data.
Devices that can process the S/PDIF protocol can be connected
to the coaxial digital interface (RCA sockets on the panel). These
include DAT recorders and a wide range of HiFi components, as
well as other computers.
UF400e Firewire Audio Expansion Board Users Manual

always connected “crosswise”, meaning OUT to IN and vice-versa. MIDI sequencer
software usually offers you to loop MIDI data through, using the Through function.
Drivers
The Windows drivers
The UF400e audio interface features a range of drivers for a variety of applications.
The audio drivers support all bit rates between 8 and 32 bits with all common sample
rates between 32 and 192 kHz. (Digital I/O up to 96 kHz)
The MME wave driver.
In most Windows programs, you will encounter drivers with the designation “
UF400e (0) MC Out” for recording and playback. These are multichannel drivers
that support all six outputs (4 analog and 2 digital). The speci c routing options for
these drivers can be found in the UF400e Control Panel.
The ASIO driver and the ASIO Control Panel
The abbreviation ASIO stands for “Audio Streaming Input Output” and refers to a
32-bit driver model developed by Steinberg. The advantage of the ASIO driver is
the extremely low audio recording and playback delay times, also known as latency.
Values signi cantly under 10 ms—and less than 4 ms on fast, cleanly-con gured
systems—at sample rates exceeding 96 kHz are quite realistic. The format also
supports sound Boards with multiple inputs and outputs—so-called multi-I/O Boards
—as well as direct monitoring and multi-client mode (ASIO 2.0 or later).
Programs that make use of Steinberg’s ASIO interface indicate in the corresponding
dialogs the ASIO drivers of the UF400e. The ASIO driver is listed in compatible
programs under “ASIO for UF400e FireWire series”.

The inputs and outputs (generally called “busses” or “channels”) available in the
individual programs are generally called “Out 1 UF400e”, “Out 2 UF400e”, etc.
ASIO audio connections in WaveLab 5
The GSIF driver
The GSIF driver of the audio interfaces is also visible only in certain programs.
The GigaStudio sampler application and other Tascam / Nemesys products can also
access the hardware in a very fast and direct manner. The outputs available in each
program are called here “UF400e (0)” and lead directly to the outputs of the UF400e
audio system.
The MIDI driver
For the recording and playback of MIDI data via the MIDI IN and OUT jacks, a
separate driver is available. The driver designated as “UF400e(0) Midi In 1 or Out
1” in this system, and it can be selected in any situation in which its use would be
appropriate.
In detailspecial properties of the drivers.
DirectSound & WDM
It goes without saying that the drivers of the UF400e also support Microsoft’
s DirectSound or DirectSound 3D interface. What’s more, the software complies
strictly with Microsoft’s WDM speci cation. For example, the drivers are able to
play back audio data streams from multiple applications in parallel (multi-client, a “
Practical tip:
If MIDI  les, which can be played back using
Windows’ media players, are also to be transferred to externally
connected devices, open the “Sounds and Multimedia Properties
” dialog window from the Windows Control Panel and set the “
MIDI Music Playback” device to the driver mentioned above.
