Connect a USB ‘B–A’ type lead (as illustrated at left) from the DacMagic’s USB input to one of the USB ports on the PC. This is the normal type of USB lead with an oblong plug at one end and a square plug at the other. Switch on the DacMagic using the front panel On/Off switch and make sure that the USB input is selected (USB LED lit). The Windows “Found New Hardware” dialogue bubble should now appear at the bottom right-hand side of the Windows desktop. The description of the DacMagic will be displayed as “USB audio device”. Installation should be automatic and no driver disc is required. After a few seconds the message “Your new hardware is installed and ready to use” should appear to confirm that installation has been successful.

Important Note: The PC’s previous audio output device should now be temporarily disabled and the DacMagic becomes the default audio playback device for the PC. This can be confirmed in the Control Panel’s Sounds, Speech and Audio Devices properties window under the Volume tab.

The DacMagic is described as a “C-Media USB Headphone Set” as we use a C-Media USB interface IC running a headphone (i.e. two-channel) profile.

If you wish to disconnect your DacMagic and return to using your previous soundcard, etc., simply disconnect it or switch off the power on the front panel.

If the PC fails to disable the DacMagic and automatically re-enable your default soundcard, you can manually disable the DacMagic in the hardware device manager. To do this, navigate to the Device Manager (click Start — Control Panel — (Vista: Performance and Maintenance —) System — Hardware

Device Manager in Windows XP). Scroll down the device manager window and expand the heading Sound, Video and Game Controllers to display a list of the connected devices. The DacMagic will be listed as “USB Audio Device”. Click on this description to highlight in blue and then click on the Disable

icon ( ) at the top of the window. A warning message will appear: “Disabling this device will cause it to stop functioning. Do you really want to disable it?” Click Yes to disable the DacMagic. The previous audio playback device will now be re-instated by Windows.

Note: As Windows operating systems evolve, the path sequence to the device manager may change. However, the DacMagic will always appear as a “USB Audio Device” in the Sound, Video and Game Controllers window.

Note: It is also possible to disable the DacMagic in the device manager by right-clicking on the highlighted “USB Audio device” and then clicking Disable from the sub-menu window.
