Audiophile USB Driver & Software Installation
The Audiophile USB system includes a “Software Drivers CD” for
Windows and Macintosh, containing all Windows and Macintosh drivers
(including ASIO drivers), and Audiophile USB Control Panel software.To
install on your system,please follow these steps:
Windows Installation
An “Installer” program is provided for Windows operating systems. The
Audiophile USB Installer greatly simplifies the work that the Windows
New Hardware Wizard has to do, and helps to ensure a trouble-free and
simplified installation.
You may also notice that a “Windows Driver Signing” dialog box will pop
up a few times during the installation, and you will be asked to press
“Continue Anyway.” This dialog box indicates that this is a relatively new
product. While we are going through the driver certification procedure
with Microsoft,we assure you that your Audiophile USB drivers are of the
highest quality, and will cause no problems in your system.
1. Insert the Drivers CD into your CD ROM drive. Locate and open the
Audiophile USB folder. Double click on the Audiophile USB Installer
program in that folder.

page of the System Properties dialog box.The Device Manager page can be
opened by right-clicking on “My Computer ,” either from the Start menu or
your desktop (depending on your operating system), and selecting
“Properties” from the list.Select “Har dware,” then “Device Manager.” With
the Device Manager displayed, click on the “+” next to “Sound,video and
game controllers” to open a list of devices, the Audiophile USB being a
device of that nature. You will also see an entry for the Audiophile USB
under “Universal serial bus controllers.” Below is an example view of the
Device Manager.
This example shows the M-Audio Audiophile USB entries in the Windows
Device Manager device list. The Audiophile USB is properly installed with
no conflicts. If you do not see your M-Audio Audiophile USB in your
Device Manager in this fashion,please jump ahead to the “Troubleshooting”
section of this manual.
Verifying Control Panel Installation, PC/Macintosh

Audiophile USB” icon will be displayed in y our Windows Control Panel,which
can be accessed from the Start menu.By double-clicking on that icon,you will
launch the Audiophile USB Control Panel software.Once the Audiophile USB
Control Panel software has been opened,you will see the various controls for
enabling inputs and outputs and for setting other parameters.
With the control panel open,you will see in the lower left hand corner a
checkbox that states, “Place Audiophile icon in the task bar.” You may
create a shortcut on your Windows taskbar by clicking on this checkbox.
Upon closing the control panel, the M-Audio logo will appear in your
taskbar. Double-clicking this icon will then open the Audiophile USB
Control Panel. Unchecking the control panel checkbox will remove the
M-Audio logo from the taskbar upon closing the control panel.Note that
the M-Audio logo will only appear on the taskbar when the Audiophile is
attached and powered “On.”

On Macintosh: During the driver installation, a dialog box will ask you if
you wish to place a shortcut to the control panel on your desktop .Clicking
this checkbox will, upon completion of the driver software installation,
place a shortcut to the Audiophile USB Control Panel on your computer’s
desktop.The control panel program itself will install to your system’s hard
drive. In OS 9, the Audiophile USB Control Panel will be placed in the
Control Panel folder, which allows it to be accessed from the Apple
Control Panel drop-down list.In OS X, the control panel is installed into
the System Preferences folder.
If you choose not to place a shortcut icon on your desktop during the
installation process,you may create an alias by highlighting the Audiophile
USB Control Panel on the hard drive and pressing the Command Key+M.
The alias may then be dragged to the desktop.The control panel can be
launched from any of the above locations. Once the Audiophile USB
Control Panel software has been opened,you will see the various controls
for enabling inputs and outputs and for setting other parameters.
NOTE: When using a music software program that is ASIO capable,
launch the Audiophile USB Control Panel software from within that
program. If you need to change the master clock settings, for
instance (in other words,change from the Audiophile’s internal clock
to an external clock by selecting “S/PDIF In” from the control panel),
it is desirable to launch the music program first, and then the
Audiophile USB Control Panel from the program’s “launch” or
“control panel” button. Without the music program open however, it
is okay to open the Audiophile USB Control Panel from your desktop
or other location.
The Audiophile USB Control Panel
Certain audio settings are made in the USB Audiophile Control Panel,and
are important to the way the Audiophile performs.You may never need to
change them for your particular purposes,but it’s good to know how these
settings affect what you do and how they interact.
When the Audiophile USB driver and control panel software are first
installed, a “default” setting is created that will work for you in most
circumstances. The analog inputs are active, as well as the analog outputs
and the S/PDIF output. The S/PDIF Input is left unchecked. The “16-bit”
radio button is selected, but can be switched to 24-bit if you wish to
record at that bit depth from your music program. The Audiophile is
capable of recording at sample rates up to and including 48000Hz.
You should only check the S/PDIF Input por t if you are recording audio
from the S/PDIF Input, or otherwise wish to synchronize to an external
10

sampling clock. Continue reading this section for more information on
making selections in the Audiophile USB Control Panel.
Active Channels & Sample Depth: Activation of the Analog and
S/PDIF inputs and outputs is done with a set of four check boxes.Two radio
buttons allow selection between sample bit depths of 16-bit or 24-bit.
These settings will interact with each other, either expanding or limiting
your Active Ports, Sample Depth, and/or Maximum Sample Rate settings.
Using the full USB bandwidth will allow for 4x4 audio streams at 16 bits
with a sampling rate of 48kHz or below .A higher bit depth or sampling rate
will demand a trade-off from your system, which can be achieved by
disabling your Active Ports.
On the right side of the control panel there are two columns labeled
“Active Channels” (Analog and S/PDIF inputs and outputs) and “Sample
Depth” (16-bit and 24-bit). Choosing the 24-bit setting will allow your
music program to record at any bit depth up to 24-bit, depending on the
variety of selections within that program.
With any combination of three stereo pair “Active Ports” enabled, the
Audiophile USB is capable of 48kHz or 44.1kHz (or lower) sampling rates at
either 24- or 16-bits.When you uncheck and deactivate any one of the Active
Ports, the 24-bit option will become available.If you select the 24-bit radio
button, and then activate all four Active Ports, the control panel will
automatically switch back to the 16-bit setting and gray out the 24-bit option.
NOTE: Please exit any audio applications running before switching
between bit depths.
The Audiophile USB will perform at 96kHz sampling rate with any one of
the stereo pairs enabled,and with the 24-bit Sample Depth selected.This
is most useful if your CD/DVD player is capable of playing “audiophile”
96kHz recordings.The Audiophile USB will not operate at 96kHz when the
control panel is set to 16-bits.In the example below,Output 1&2 is enabled
and 24-bit Sample Depth is selected, with the Maximum sample rate
showing 96kHz.
