1. Overview

Thank you for choosing Waveterminal U2A, an USB digital audio
interface.

Waveterminal U2A (U2A) is an USB digital audio interface employing
24-bit A/D, D/A converters for both of IBM compatible computer system
and Macintosh computer 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.

FEATURES

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 give s 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.

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

4

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 disconnected from 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 a
screwdriver what so ever. Only thing that you have to remember is
that your computer system has to have an USB port.

HARDWARE 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. Find the USB port on your Mac. USB port is looked

like below.

USB port on computer

2. 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

3. Connect the other end of the USB cable (Series B

plug) to the USB port of U2A.

4. Hardware installation is done. Now you will see that

Power LED on the U2A is on. USB device is so easy
to install you can just plug it in to use.

) 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

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.

BASIC CONNECTIONS

In a typical audio production studio or workstation, where you have
both digital and analog devices, this set up treats your MAC 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.

If you plan to use U2A in a digital mastering environment, you may
choose to connect analog outputs of U2A directly to your power
amplifier’s inputs instead of sending it through the console/mixer.
