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. 2. As the Installer loads the Audiophile USB drivers, a Windows Driver Signing (XP and 2000 Users only) dialog box may pop up a few times during the installation. Click, Continue Anyway. 3. When asked to switch On your Audiophile USB, do so.This will bring up the Windows New Hardware Wizard. Click Next at each prompt, and the Hardware Wizard should automatically recognize all of the Audiophile Drivers.

NOTE: Windows 98SE users will need their Microsoft Windows 98SE CD-ROM here.
4. The Wizard reports that Windows has finished installing the software. Click Finish.Your Audiophile USB is ready for action.
After completion of the driver installation, Windows may require you to restart Windows. If it does request a restart, remove the Drivers CD from the CD drive and respond by clicking Yes. The system will restart and your Audiophile USB is ready for play. Macintosh OS 9 Installation
NOTE: To use the Audiophile USB on Mac OS 9, you must also install Opcodes OMS. This should be done BEFORE running the Audiophile USBs Installer program. By installing OMS first, the Installer program will then be able to place the OMS driver in the proper folder. Then, after running the Installer, you will need to configure OMS. See the section, OMS Configuration, for more information on installing and configuring OMS.
1. Insert the Drivers CD into your CD ROM drive. Locate and open the Audiophile USB folder. Open the folder for your current Macintosh OS, and double click on the Installer program in that folder. 2. As the Installer loads the Audiophile USB drivers, you will be asked if you wish to place a shortcut to the Audiophile USB Control Panel on your desktop.This is your choice, but its probably a good idea to choose this option.You can always trash the shortcut if you find it unnecessary. 3. After you run the Installer, you may switch On your Audiophile USB. Your Audiophile USB is now ready for action.
OMS Configuration To configure the Audiophile USB for MIDI on Mac OS 9.x, you will need to have Opcodes OMS (Open Music System) installed first. OMS is a MIDI Manager program, and it is necessary to install this in order to run all OS 9 music programs that have a MIDI engine, i.e., programs that use MIDI. You need to install OMS before you run the Audiophile USBs driver Installer program. OMS is provided on the Drivers CD that came with the unit, and is located in the OS 9 folder, or it can be downloaded from the M-Audio Websites Drivers page. Opening the OMS 2.3.8 folder and double-clicking on the Install OMS 2.3.8 program will install OMS in your system. Restart your computer, and continue with the driver installation (see previous section). To configure your Audiophile USB MIDI in OMS, go to the Control Panel or Chooser under the Apple Menu, and make sure AppleTalk is turned off

(this is recommended, although OMS will sense that it is on and prompt you to turn it off). If you are configuring OMS for the first time, follow these instructions to configure OMS.
1. In the Opcode folder, which you will find on your hard drive, locate the OMS Applications folder,then OMS Setup. Double-click on OMS Setup. 2. OMS will inform you that it has not yet been configured. Click OK. 3. The Create a New Studio Setup dialog box now appears. Click OK. 4. The OMS Driver Search dialog asks you to choose the port on which youve attached the Audiophile USB MIDI (either Modem or Printer). DO NOT choose a port, just click Search. OMS begins Searching. 5. OMS Driver Setup shows the Audiophile USB MIDI in a list when OMS successfully finds the driver. Click OK. OMS will now define (shows Identifying) the Audiophile USB output port.The OMS MIDI Device Setup dialog box will appear showing the Audiophiles output port with a check box to the left of the port, indicating that the port is enabled. Now click on OK. 6. Next, the My Studio Setup appears with a file save dialog box over it. You will now need to save your new Studio Setup before you can assign an instrument to the Audiophiles MIDI output and input. Assign your instrument and you are done. You may now exit OMS Setup by quitting the application.

Mac OS X Installation is now complete. Proceed to the next section, Hardware Installation. Verifying Windows Driver Installation Windows displays the Audiophile USB driver status in the Device Manager 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 Hardware, 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 On the PC: Once the Audiophile USB is properly installed, an M-Audio Audiophile USB icon will be displayed in your 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 computers desktop.The control panel program itself will install to your systems 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: 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.
If you activate both sets of input and output channels, you will notice that the 24-bit setting in the Sample Depth column is grayed out and the Maximum sample rate is shown as 48000 Hz.
NOTE: Whenever S/PDIF Input is selected as an Active Port, the Audiophile is expecting a digital signal at that port and to lock to the sample rate of that signal. When S/PDIF Input is selected and there is no signal present at the S/PDIF Input port, or the S/PDIF signal is not recognized or invalid, the Audiophile USB will not operate properly. Most likely, you will hear audio from the Audiophile, but it will be running at an odd sample rate and sound like it is playing at the wrong speed.
DD/DTS Pass-Thru: Just below the Sample Depth column, you will see a checkbox labeled,DD/DTS Pass-Thru. If you are using a Software DVD player and wish to send encoded multi-channel audio such as Dolby Digital or DTS to the Audiophile USBs S/PDIF output port, then check this box. If you are only sending stereo audio (standard PCMnot encoded surround) to the S/PDIF output port during normal operation, then leave this box unchecked. If you have this box checked, you can still send stereo digital audio to the S/PDIF port without any problems. However, you will notice that when the DD/DTS Pass-Thru box is checked, ONLY the S/PDIF port is active in the Active Ports column. Unchecking the DD/DTS Pass-Thru box will restore the port selection to the previous configuration. Latency: Driver Latency can be selected from a range of values shown in a drop-down list located just below the Maximum Sample Rate. The default setting when the Audiophile is first installed is Very High. Because slower computer systems require larger sample buffers to avoid dropouts in the audio stream, a higher latency value is often necessary. How low you will able to set the Latency will depend on several factors, such as your systems performance and the performance of the music program itself. To test your system for lower Latency, try the very low setting first (as shown in the previous screenshot), and if your system stutters or performance falters, try the next higher setting until the system performance stabilizes. Once you are satisfied with any of the control panel settings, click OK to close the Audiophile USB Control Panel. Version Numbers: The lower left corner the Audiophile USB Control Panel page displays the ASIO Driver Version, USB Driver Version, and the Firmware Version numbers currently in use. This is useful when checking for driver updates on the M-Audio website, or in the event that you need to call tech support and give them your system information.

The Audiophile USB also has digital inputs and outputs in S/PDIF format. These are available on RCA connectors, as stereo pairs.These jacks receive or transmit a digital audio stream that is independent of the analog audio streams. However, because of the bandwidth limits of USB there can be a tradeoff between the number of inputs and outputs that are active and the sampling rate and bit depth of the audio being processed.Also, you should ONLY activate the S/PDIF Input if you are connecting an active digital audio device to this input.This is detailed in the previous section,The Audiophile USB Control Panel. Also detailed in the previous section is the use of the S/PDIF Output for sending encoded surround sound signals. Checking the DD/DTS Pass-Thru box in the Audiophile USB Control Panel will allow you send Dolby Digital, Dolby Surround, DTS, or any encoded surround sound signal to the S/PDIF Output of the Audiophile USB.You can connect this output to a home theater system, or any device that will decode this signal. Using most DVD players, select the S/PDIF option in the DVD players audio setup page, and your computer becomes a high-end home theater player in conjunction with the Audiophile USB.
Audiophile USB with Your Music Software
Once the Audiophile USB hardware and software drivers are properly installed, the Audiophile is ready for use with your music application software. Some software applications may require you to highlight or enable the Audiophile USB drivers within the program in order to use the Audiophile, while others may have a utility that analyzes or profiles the audio devices in your system and enables the drivers.Your software should have an audio device driver setup page. If you have problems locating it, consult your softwares documentation. The Audiophile drivers include MME and WDM drivers for Windows, ASIO drivers for both Windows and Mac, and Sound Manager drivers for Mac. WDM drivers are a more modern driver architecture for Windows operating systems Me, 2000, and XP, but only certain programs like Cakewalks Sonar will take advantage of them. Other Windows programs will automatically access and use the MME drivers.WDM drivers, similar to ASIO, will give you
low latency monitoring through the application (check your applications documentation for information regarding input monitoring). If your Windows or Macintosh program is ASIO compliant, like Steinbergs Cubase or Emagics Logic, then the programs audio device driver setup page will allow you to select the USB Audiophile ASIO driver.This selection is advised, and described more fully later in this section. Windows MME and WDM Audio Input Devices: Within the setup page of your software application(s), the names of the Audiophile USB audio input devices will be: M-Audio USB Audiophile Line, and M-Audio USB Audiophile SPDIF. The M-Audio USB Audiophile Line device allows recording a stereo stream directly from the analog Left and Right Input pair, while the M-Audio USB Audiophile S/PDIF device allows you to record a stereo stream directly from the S/PDIF Input.

Note that the input devices are stereo. Your application software may break these down further to left and right mono devices. Therefore you may see them as Left M-Audio USB Audiophile Line and Right M-Audio USB Audiophile Line, or Left M-Audio USB Audiophile S/PDIF and Right M-Audio USB Audiophile S/PDIF from within your recording software. If your application allows for recording stereo tracks, you will also be able to select Stereo M-Audio USB Audiophile Line and Stereo M-Audio USB Audiophile S/PDIF.
Windows MME and WDM Audio Output Devices: Within your software application(s), the names of the Audiophile USB audio output devices are: M-Audio USB Audiophile Line, and M-Audio USB Audiophile SPDIF Most application software will handle the outputs as stereo pairs but allow you to pan audio left or right within the pair. Therefore, to send a mono output to the Audiophiles Left Output (for example), choose M-Audio USB Audiophile Line and pan that track hard left.To send a mono output to the Audiophiles Right Output, choose M-Audio USB Audiophile Line and pan that track hard right.
ASIO Input and Output Devices: If your music program is ASIO compliant, you may use the USB Audiophile ASIO driver with your Audiophile USB. Open your music program and go to the audio setup page. The USB Audiophile ASIO driver will show up in the programs ASIO Driver list, allowing you to select it at this time if it is not already selected by default. If you are using an ASIO compliant music program, we suggest that you enable and use the Audiophiles ASIO drivers.ASIO gives you the advantage of being able to monitor your source through the program, similar to monitoring the record inputs of a tape machine. ASIO input devices will appear as: M-Audio M-Audio M-Audio M-Audio USB Audiophile USB Audiophile USB Audiophile USB Audiophile Line Left, Line Right, SPDIF Left, and SPDIF Right.
ASIO Output devices will appear as these stereo pairs, which you will be able to pan left and right from within your music program: M-Audio USB Audiophile Line, and M-Audio USB Audiophile SPDIF. Once the Audiophile USB ASIO driver is selected in your music programs audio setup page, you will find a button that allows you to launch the ASIO devices control panel. Clicking this button will now launch the Audiophile USB Control Panel, allowing you to view the Audiophile USB audio settings.

Audiophile USB MIDI Setup
The Audiophiles MIDI input and output ports may be connected to external MIDI devices.The following diagram shows connection to a MIDI keyboard instrument, which is also being used as a sound module.The MIDI output of the Audiophile USB may be used with just a sound module, while the MIDI input may alternately be used to receive MIDI time code for synchronization purposes.
1. Connect the MIDI out port of your controller keyboard to the Audiophiles MIDI In port using a standard MIDI cable. 2. Connect the Audiophiles MIDI Out port to the MIDI in of your keyboard instrument (or a sound module), also using a standard MIDI cable. 3. Connect the audio outputs of the keyboard to either a mixer, sound system, or the audio inputs of the Audiophile USB.
The Audiophile USB MIDI drivers, once enabled in your softwares MIDI Setup, will appear as a MIDI source and a MIDI port within that programs track configuration windows. The MIDI input driver is named In Audiophile USB, and the MIDI output driver is named Out Audiophile USB. Some software applications allow you to redefine/rename these devices per supplied or manually entered instrument definitions.

Troubleshooting

Problem: No sound output. Possible Cause 1:The Audiophile USB hardware or software device drivers are not properly installed.See the installation sections of this manual for further information. Possible Cause 2:There is a resource conflict between your computers USB controller and another device in your computer (PC only). Check the Device Manager for your USB controllers IRQ against those of the other installed devices. If necessary, change the settings for the one or more of the devices (refer to your computer or motherboard manual). Possible Cause 3:Your application software has not been properly configured to use the Audiophile USB as its audio output device. Possible Cause 4: Improper connections of the audio accessories.Verify that the Audiophile USB analog audio outputs are properly connected to a digital mix deck or external mixer/amplifier, or the S/PDIF Out is connected to an external digital audio device capable of receiving S/PDIF.
Problem: Im trying to record digital audio through the S/PDIF input but I dont hear any output. Possible Cause:The settings in the Audiophile Control Panel may be incorrect. Double check that you have S/PDIF Input enabled and that your settings dont exceed the bandwidth limitations of USB. Remember that the more inputs and outputs you have enabled, the lower the allowable sampling rate and bit depth.
