Note: Some computer systems ship with an OEM version of Windows 98SE that does not contain the entire
generic USB driver and audio platform or may have a soundcard that does not run Windows compliant
drivers. If you cannot select USB Audio Device in the Preferred Device Window, please refer to the
troubleshooting section at the end of this user manual for further instructions. In this situation you may not
be able to select USB Audio Device even though the USB drivers seemed to install fine when you first
plugged in the MD-Port I/O.
Windows ME
Once Windows ME starts and the appropriate drivers have been loaded, the MD-Port I/O should
automatically be set as your system's preferred audio device. To verify this, open the Sounds and
Multimedia control panel and make sure that USB Audio Device appears in both the Playback section and
Recording section under the Audio tab. You should also put a check next to the option Use only Preferred
Devices that appears at the bottom of the window. To get to the Sounds and Multimedia Properties control
panel hit Start, then go to Settings, then Control Panel. The multimedia icon will be in the Control Panel
window. Double click on the icon to open the Sounds and Multimedia Properties window. You're now fully
loaded.
Note: According to Microsoft knowledge base article Q280127 some systems running Windows ME may
require an operating system update for USB audio devices to work correctly. We recommend installing this
operating system update before installing the MD-Port I/O. The necessary update is called
280127USAM.exe and can be obtained directly from Microsoft.
Windows 2000
Once Windows 2000 starts and the appropriate drivers have been loaded, the MD-Port I/O will automatically
be set as your system's preferred audio device. To verify this, open the Sounds and Multimedia control panel
and make sure that USB Audio Device appears in both the Playback section and Recording section under the
Audio tab. You should also put a check next to the option Use only Preferred Devices that appears at the
bottom of the window. To get to the Sounds and Multimedia Properties control panel hit Start, then go to
Settings, then Control Panel. The multimedia icon will be in the Control Panel window. Double click on the
icon to open the Sounds and Multimedia Properties window. You're now fully loaded.
Windows XP
Once Windows XP starts and the appropriate drivers have been loaded, the MD-Port I/O should automatically
be set as your system's preferred audio device. To verify this, open the Sounds and Audio Devices control
panel and make sure that USB Audio Device appears in the Sound Playback section and Sound Recording
section under the Audio tab. You should also make sure that a check appears next to the option Use only
Default Devices that appears at the bottom of the window. To get to the Sounds and Audio Devices control
panel hit Start, then go to My Computer, then Sounds and Audio Devices. You're now fully loaded.
Controlling the output and volume levels
The MD-Port I/O's volume and output controls can be accessed by double clicking the standard volume
control icon, which will open a Speaker control panel. For the MD-Port I/O’s playback operations, the
volume is set by the Wave Balance slider. To activate the Wave Balance slider, go to Options and then
Properties. In the bottom section of the Properties window, make sure a check appears next to Wave
Balance. Click OK once you're done. You should now be able to see a Wave Balance slider in the Speaker
control panel.
4. We recommend rebooting your computer to ensure all changes take effect. Your driver installation for
the MD-Port I/O is now complete.
Windows XP installation
1. There's no need to turn off your computer when plugging the MD-Port I/O in for the first time. Locate
your computer's USB port and plug the supplied USB cable in. Now plug the MD-Port I/O into the
other end of the USB cable. We recommend you don’t plug the MD-Port I/O into a USB hub - other
devices on the hub may interfere with the USB audio data, causing pops and clicks in your recordings.
2. Windows XP will automatically detect the addition of a new USB device and will open a dialog box in
the bottom right hand corner of your screen. In the dialog box you’ll be able to watch as Windows XP
progress through automatically updating your USB drivers, including USB Composite Device, USB
Human Interface Device, and USB Audio Device.
3. Once Windows XP has completed updating the USB drivers, it will let you know that the installation
process has been completed and that your MD-Port I/O is now available for use. At this stage Windows
should also automatically set the MD-Port I/O as your preferred multimedia output device.
4. We recommend rebooting your computer to ensure all changes take effect. Your driver installation for
the MD-Port I/O is now complete.
Setting the MD-Port I/O as preferred audio device in Windows 98SE,
Windows ME, Windows 2000, and Windows XP.
With USB technology, there's never any need to turn off your computer when plugging in, or unplugging the
MD-Port I/O. When you want to use the MD-Port I/O, simply close any running programs and plug it into the
USB port. Your system will then automatically configure itself. When you're done, you can unplug the MD-
Port I/O and your computer will automatically revert to whatever soundcard is installed. In both cases, it
doesn't matter if the system is on or off. For smooth automatic loading, please ensure all audio programs
are closed before plugging in, or unplugging the MD-Port I/O.
Note: when the MD-Port I/O is selected as your system's preferred audio device, no sound will come out of
any speakers plugged into your soundcard. If you wish to use your soundcard instead of the MD-Port I/O,
either unplug the MD-Port I/O from the USB cable, or select your soundcard as preferred audio device in
the Multimedia Properties control panel for Windows 98SE, Sounds and Multimedia control panel for
Windows ME and Windows 2000, or Sounds and Audio Devices control panel for Windows XP. It’s not
possible to use a soundcard and the MD-Port I/O at the same time for music playback.
Windows 98SE
Once Windows 98SE starts and the appropriate drivers have been loaded, the MD-Port I/O should
automatically be set as your system's preferred audio device. To verify this, open the Multimedia control
panel and make sure that USB Audio Device appears in both the Playback section and Recording section
under the Audio tab. You should also put a check next to the option Use only Preferred Devices that
appears at the bottom of the window. To get to the Multimedia control panel hit Start, then go to Settings,
then Control Panel. The multimedia icon will be in the Control Panel window. Double click on the icon to
open the Multimedia Properties window. You're now fully loaded.
