Overview
Thank you for choosing
Waveterminal U2A, an USB digital audio interface.
Waveterminal U2A (U2A) is an USB digital
audio interface with 24-bit A/D, D/A for both of IBM PC compatible system. U2A
can be used with your digital audio recording software to record and/or
playback stereo analog or stereo digital audio sources simultaneously (full
duplex) with exceptional audio quality.
USB stands for
Universal Serial Bus, which means it connects peripherals to a computer. It is an evolved form of old serial or
parallel bus.
USB makes
installation of new peripherals much simpler, just plug and play. You do not have to pry open the PC to
add a peripheral any more, just plug and turn it on. With USB-compliant computers and peripherals, there are no
more worries about IRQ setting, DIP switch setting, or card installation. Even
the computer turned on, it is no problem with attaching and removing devices.
Just plug and play!
Practically,
there is no limit on number of devices that can be connected to the computer.
Up to 127 peripherals can be linked to the computer using USB hubs.
USB even
provide electrical power to the peripherals. It automatically detects necessary
power and supplies it, which eliminates messy power cables from working space.
Windows 98 and
Windows 2000 include built-in driver for USB compliant devices. Just look for a port and plug in.
Best of all,
take a listen and you will immediately notice the difference in the sound
quality. Digital or analog, not all audio interface cards are made the same. If
you are a professional or in need of a professional quality USB audio
interface, you have made a sound investment in Waveterminal U2A.
24-bit Analog-to-Digital and Digital-to-Analog Converters.
Highest quality 24-bit AD/DA converters in U2A provide
unmatched sound quality with exceptionally low noise.
2-In/2-Out Analog Audio Inputs and Outputs.
U2A provides 1/4¡± phone jacks for use with –10dBV nominal
level consumer audio equipment. Unlike some audio cards that deliberately boost
their output levels to give you a false sense of audio quality, U2A gives you a
true indication of your levels. Nothing¡¯s added or taken away unless you intend
to do so. If you need to adjust levels, digital level adjustment is provided
for analog inputs and outputs.
Multi-unit
Link Support
You can use multiple units of U2A simultaneously (if you
have USB expansion hub).
S/PDIF Coaxial /Optical Digital In & Out
U2A offers S/PDIF digital input and output via Optical or
Coaxial ports. There¡¯s no additional conversion process for signal already
recorded. With optional Dr. D
audio interface/converter, you have access to XLR type AES/EBU input and output
simultaneously.
Multiple Sample Rate Support
Supports all denomination of 44.1kHz or 48kHz standard
sample rates from 32kHz, 44.1kHz and 48kHz. U2A can be used in a variety of
applications.
Real-time Hardware Sample Rate Conversion
Regardless of the type of sample rates, U2A automatically
converts the incoming digital audio signal to the sample rate of your choice in
real-time.
Functions as an independent Signal Converter
When Digital
In Clock Source is selected, U2A can be operated as an independent signal
converter. In this mode, U2A is
completely disconnected with the computer, but it will send out any incoming
signal to both analog and digital output ports.
2.
Installation
One of many benefits of USB device is easy
installation. Just plug and play,
you don¡¯t need to uncover the computer case or use driver what so ever. Only thing that you have to remember is
that your computer system has to have an USB port.
WT2496 is shipped with the following contents:
1. Waveterminal U2A (1)
2. Software Disk (1)
3. User¡¯s Manual (1)
4. USB cable -2m (1)
Most of all,
your system has to have at least one available USB port to use U2A.

installation
Before you
begin, make sure you have read your computer¡¯s manual on installing USB
devices. Your computer¡¯s manual should describe the precautions you should
take.
Shutting down
computer wouldn¡¯t need for installing an USB device to the computer. However, we will take it from the start
to make sure you can follow every detail of installation.
1. Turn off the computer.
2. Find the USB port on your
computer. USB port is looked like
below. You can find it by the PS/2
or serial ports on the back of desktop computer system.
USB port on computer
3. Plug in appropriate plug of USB cable
(called Series A plug) to the USB port of computer. You will notice that USB ports on computer and U2A are
different.
Series A plug
4. Connect the other end of the USB cable
(Series B plug) to the USB port of U2A.
Series B plug
5. Turn on the computer. You will see ¡°PWR¡± LED on U2A lights in
red. U2A get the power from the
computer via USB cable so you don¡¯t need to attach any external power supplier.
) Series A
Plug is used for those devices on which the external cable is permanently
attached like Mouse, Keyboard and USB hub etc¡¦
) Series
B Plug is for that
requires detachable external cables and used for devices like Printers,
Scanners, Modems, Stand Alone Hubs.
Parts of this
manual are continually being updated. Please read the README.TXT file included
in the driver diskette for the latest update information, and be sure to check
our web site http://www.egosys.net
occasionally for the most recent update information.
3. External
Connections
U2A has many features that can enhance your audio production
environment. If you are serious enough to about your digital audio, you may
want to take time to read through this section carefully. While you may not
need all of these features, and simply opt to plug in the cables to get started
right away, you should at least be aware of U2A¡¯s capabilities – in case you
need them later on.
In a typical audio production studio or workstation, where
you have both digital and analog devices, this set up treats your PC as a
stereo master recorder. In this
case, monitoring of U2A will be similar to ¡°through-the-tape¡± monitoring, where
you monitor your input and output sources from the tape recorder¡¯s point.

Cables & Adapters
Let¡¯s talk about the cables and connectors those can be used
with U2A.
Analog connector
U2A uses 1/4¡±
phone connectors for analog input/output connectors.
The wiring method for unbalanced
connections with XLR connectors to ¨ù¡± phone connectors (tip and sleeve only)
using shielded twisted pair cable (2 wire + shield) is as follows:
The wiring method for unbalanced
connections with XLR connectors to unbalanced ¨ù¡± phone connectors (tip and
sleeve only) using coaxial cable (1 wire + shield) is as follows
:
Digital connector
1.
Coaxial
connector
S/PDIF (IEC-958) uses 75ohm Coaxial cable and RCA
connectors. U2A uses RCA connector
that is the same cable as used in video transmission. Shown below is conventional RCA connector and you can use
this for transmitting/receiving S/PDIF digital audio data from/to U2A.
2.
Optical
connector
Optical version of S/PDIF interface, which is usually,
called Toslink, because it uses Toslink optical components. The transmission media is 1mm plastic
fiber and the signals are transmitted using visible LED light. The optical signals have exactly same
format as the electrical S/PDIF signal, they are just converted to light
signals.
4. Driver Installation
If the hardware installation was done properly, your
computer will look for the drivers need to use U2A and start to install them.
1. Computer will recognize the new device and ¡°Add New Hardware

Please read
the README.TXT file included in the driver diskette for the latest driver
update information, and be sure to check our web site http://www.egosys.net occasionally for the
most recent update information
5. U2A Control Panel Reference
If you have
properly installed hardware and software driver for U2A, your system will
display icon on your desktop system menu bar.
Click it once and it will display the Waveterminal U2A Control Panel as below.
For user¡¯s convenience, U2A control panel is designed to follow logical route
of audio signal. Upper left
section of the control panel shows input status and selected input goes to
level fader section. Right section
of the control panel is for output status selection. Lower part is occupied with sync option and digital format
selectors. While reading through this section, it may help to
actually sit down in front of your PC
and experiment.
Input/Output Level
Faders
1. Level Faders
Click and drag to
change the input and output levels. U2A is fixed to use –10dBV input/output
reference level. Check the manuals of the audio equipment you want to connect
to U2A¡¯s inputs. It should be –10dBV device. The numbers on the bottom show the
relative levels in dB. When you
place mouse cursor over the level fader, fader will light in blue and mouse
cursor changed to cross arrow figure.
You can use wheel mouse or click the fader and drag to adjust the value
of I/O level.
2. GANG
MODE
Links the L-R faders
for stereo operation. Un-select the Gang Mode if you need to control the left
and right levels independently.
usb
wave In select
Select the
input source type for audio recording.
1. ANALOG IN
Selects the analog
input port (-10dBV unbalanced) on the U2A as the USB wave input source.
2. DIGITAL IN
Selects the digital
input port (SPDI/F Coaxial or Optical) on the U2A as the USB wave input source.
Digital In
select
Select the
input connector type for your digital audio input.
Selects the Coaxial
input port (RCA type S/PDIF format) on the U2A as the digital input source.
2. OPTICAL
Selects the Optical
input port (Toslink, S/PDIF format) on the U2A as the digital input source.
Clock Source
determines that U2A will reference to. Clock Source is the time reference that
determines precisely where each digital audio sample begins and ends. Also, Clock Source in U2A control panel
gives unique function to the unit by selecting between two different sources.
1.
INTERNAL
Selects U2A¡¯s
on-board clock source as the reference.
This is the default mode for recording analog/digital audio through U2A.
Use this mode if you are recording audio signal, playing back audio file or
using Realtime Sampling Rate Converter.
2. DIGITAL IN
Selects the digital audio input¡¯s data
as the clock source. Selecting this mode causes U2A functions as an independent
operation status from computer. As
you can see below, USB WAVE IN SELECT section is disappeared and USB
WAVE OUT of ANALOG/DIGITAL OUT MIXER section is disabled.
In this mode, you can
operate U2A as a signal converter, but U2A is now completely separate from the
computer. That means you cannot
record any input source to the computer and play any audio source from the
computer. However, any incoming
audio signal (either analog or digital) can be sent out through three different
output ports. Analog audio signal
can be converted to digital audio data, digital audio data would be converted
to analog audio signal and even digital audio data can be transferred to
different connector type.
This is where you select the source
that is routed to the Analog Output jacks of U2A. You can select either Analog In or Digital In for input
monitoring. USB WAVE OUT can be
selected simultaneously with one of the input source monitoring.
1.
ANALOG IN
Signal connected to
Analog Input ports of U2A is routed to the Analog Output ports for input
monitoring.
2. DIGITAL
IN
Signal connected to Digital Input port
of U2A is routed to the Analog Output ports for input monitoring.
3. USB
WAVE OUT
Output of wave device selected to USB Audio Device is routed to the Analog
Output ports for monitoring.
This is where you select the source
that is routed to the Digital Output jacks (Coaxial and Optical) of U2A.
1. ANALOG IN
Signal connected to Analog Input ports
of U2A is routed to the Digital Output ports for input monitoring.
2. DIGITAL
IN
Signal connected to Digital Input port
of U2A is routed to the Digital Output port for input monitoring.
3. USB
WAVE OUT
Output of wave device selected to USB Aduio Device is routed to the
Digital Output port for monitoring.
When more than one output source is
selected to be played back simultaneously in the Analog or Digital Out Mixer,
you are actually combining the data of two digital audio signals together,
resulting in an overall gain of about 6dB/bit for each signal combined. This
can cause the output circuit to overload and create a noticeable click or
distortions as the combined level can exceed 0 dB peak level. Mix Mode gives
you the choice as to how such excessive levels are handled by U2A.
1. DYNAMIC
The combined signal
levels are not adjusted by U2A. In this mode clipping signals are audible, but
left untouched. If you want to adjust the levels, you can do so by adjusting
the levels from the audio software or by manually reducing the output level
faders of U2A.
2. SOFT
The combined signal
levels are reduced automatically by U2A, depending on the number of signal
sources combined. For two combined signals, the output signal is reduced by –6
dB.
If output
monitoring sources don¡¯t contain peak level (0 dB peak) programs, combining
them probably would not cause any clipping or distortion. In such cases, you
may opt for the Dynamic mode, as it will allow you to add the signals for a
much ¡®hotter¡¯ output. On the other hand, if your sources already contain peak
level programs, you may need to select the Soft mode or manually adjust the
levels of each output source you have selected.
SAMPLe RATE
Sample rate
determines the number of samples per second that is used to convert analog
audio to digital audio.
As most of you may know, sample rate
for CD-DA is 44.1kHz and professional digital audio masters are usually
recorded at 48kHz sample rate. U2A may be used to sample analog audio at 48kHz,
but at some point in time it must be converted down to 44.1kHz for it to be
used in a viable consumer format, such as CD-DA. Once you convert (dither) the
data down to a lower sample rate format, you will experience some losses in
frequency response. However, analog audio recorded with higher sample rate and
bit resolution will sound cleaner and retain more accurate frequency response
when they are dithered down to lower bit rate or converted to lower sample
rate.
1. AUTO
Sample rate is
automatically set by the selection you make in your digital audio recording
software during analog audio recording or by the encoded signal format during
digital audio recording.
2. SAMPLE RATE
There are three
different sample rates available – 32kHz, 44.1kHz and 48kHz. If you want to convert sample rate in
real time, you can select desired sampling rate among them.
REALTIME
SAMPLE RATE CONVERTER
U2A can
function as a real-time sample rate converter. This is U2A¡¯s unique function
that you cannot find from any other digital audio interface. You can change the
incoming digital signal to a different sample rate by choosing Internal word clock and selecting a
desired sample rate. The maximum conversion ratio is 3:1, so if your input
signal¡¯s sample rate is 96kHz, you can convert it down to 32kHz (96/3) or convert 11kHz signal up to
32kHz (11x 3). Real Time Sample
Rate Converting functions only for incoming digital signal. Connect digital source to
Coaxial/Optical Input port and choose desired sampling rate. Now the sampling rate of the signal you
can get from digital output port is converted.
However,
you cannot change the sampling rate of .wav file that playback through the
application. If you try to convert
it, it only sounds like sampling up (faster speed than normal) or sampling down
(slower than normal).
Digital Out Type selector determines
the type of data format to be used on the digital output jack of U2A.
Generally known as
S/PDIF (Sony Phillips Digital Interface), select this mode if you are sending
digital audio output from U2A to a S/PDIF equipped audio device.
2. PROFESSIONAL (IEC 958 Type I)
Generally known as
AES/EBU, select this mode if you are sending digital audio output from U2A to
an AES/EBU audio device.
Important Notice: Since the adaptation of IEC958 no longer distinguishes
between S/PDIF and AES/EBU, some of the older AES/EBU audio equipment require a
higher signal level than U2A¡¯s digital output levels (which conform to IEC 958
standards). If you experience problems transferring digital audio from U2A to
an AES/EBU equipment, you may need a signal converter such as EGO SYS¡¯s Dr. D
to boost the level.
By clicking
right button of the mouse once while mouse cursor is placing over the U2A
control panel, there are several control menus appeared.
1. Close Panel
Close U2A Control
Panel.
2. Always on Top
Makes U2A Control
Panel the top most window visible on the Windows desktop.
3. Find U2A
When USB plug
connected loosely or the connection broke for some reason, U2A control panel
will send the message ¡°USB is not working. Please re-connect usb¡± on U2A
control panel window menu bar.
Unplug USB cable and plug it again then select this menu to find the
U2A. When you re-connect U2A to
the computer, allow 5~10 seconds for computer to recognize an USB device.
6. Application
With most digital audio applications, you will find USB Audio Device once it has been
installed properly. It¡¯s just a matter of selecting the sample rate and the bit
depth of your preference from thereon. We have included a few applications
including Samplitude Project v5.5 – bundled software with U2A - below just as a
quick setup guide. You should refer to the specific application¡¯s manual on how
to optimize the audio recording and playback capabilities. If you have problems
or questions with setting up U2A on your application please contact our
technical support.
You need to
set the output device and input device when you run the Samplitude Project v5.5
for the first time.
Hit the ¡°?¡±
button at the very left side of the track window to open the ¡°Track Info¡±
window. You can set U2A as the
output device by choosing USB Audio Device under ¡°Track Playback
