1. Overview

Thank you for choosing ESI Waveterminal U24, an USB digital audio
interface.

Waveterminal U24 (U24) is an USB digital audio interface with 24-bit
A/D, D/A for Apple Macintosh computers and IBM PC compatible
system. U24 can be used with your digital audio recording software to
record and playback simultaneously (full duplex) through stereo analog
or stereo digital audio sources 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 don’t have to 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 linked to
the computer using USB hubs.

USB even provide electrical power and supplies it, which eliminates
messy power cables from working space.

If you are a professional or in need of a professional quality USB audio
interface, you have made a sound investment in Waveterminal U24.

2. Features

24-bit Analog-to-Digital and Digital-to-Analog Converters

Highest quality 24-bit AD/DA converters in U24 provide unmatched
sound quality with exceptionally low noise.

2-In/2-Out Analog Audio Inputs and Outputs and Headphone connector

U24 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, U24
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. You can
also use Analog Out L as Headphone connector.

S/PDIF Coaxial /Optical Digital In & Out

U24 offers S/PDIF digital input and output via Optical or Coaxial ports.
There’s no additional conversion process for signal already recorded.

Multiple Sample Rate Support

Supports all denomination of 44.1kHz or 48kHz standard sample rates
from 32kHz, 44.1kHz and 48kHz. U24 can be used in a variety of
applications.

Real-time Hardware Sample Rate Conversion

Regardless of the type of sample rates, U24 automatically converts the
incoming digital audio signal to the sample rate of your choice in real­time.

Functions as an independent Signal Converter

When Digital In Clock Source is selected, U24 can be operated as an
independent signal converter. In this mode, U24 is completely
disconnected with the computer, but it will send out any incoming
signal to both analog and digital output ports.

ASIO2.0 and MME driver support

You can use U24 with ASIO2.0 applications such as a Cubase, Nuendo
and also MME applications such as Cakewalk, Samplitude.

3. System Requirement

Most of all, your system has to have at least one available USB port to
use U24.

PC

1. Intel Pentium II 400 MHz CPU or equivalent AMD CPU

2. Windows 98SE/ME/2000/XP operating system

3. 1 open USB port

4. 128MB RAM

5. Digital audio recording/playback software

MAC

1. Power Macintosh G3 or higher

2. Mac OS 9.0 to 9.2.x

3. One available USB port

4. “USB Device Extension” version 1.4.1 or later is needed

5. 128MB of RAM
(Highly depends on the system requirements of your audio software)

4. 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 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

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 U24 are different.

Series A plug

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

the USB port of U24.

Series B plug

4. Turn on the computer. You will see “PWR” LED on U24

lights in red. U24 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
check our web site http://www.egosys.net occasionally for
the most recent update information.

5. External Connections

U24 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 U24’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 PC or Macintosh
as a stereo master recorder. In this case, monitoring of U24 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 U24 in a digital mastering environment, you may
choose to connect analog outputs of U24 directly to your power
amplifier’s inputs instead of sending it through the console/mixer.

CABLES & ADAPTERS

Let’s talk about the cables and connectors those can be used with U24.

Analog connector

U24 uses 1/4” phone connectors for analog input/output connectors.
The wiring method for unbalanced connections with XLR connectors to
¼” 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 ¼” 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.
U24 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 U24.

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.

6. Driver Installation in PC

1) XP

If the hardware installation was done properly, your computer will look for
the Windows native drivers need to use U24 and start to install them.

After Windows native driver was done properly, you must keep going to
next exclusive U24 driver.

1. Insert the provided Driver CD or diskette into the CD-Rom drive or
floppy disk drive and (or unzip U24 file and) copy all the files to a
