Windows XP recognition instructions
1. Plug the U1 into the USB port on the computer.
(When using a USB hub, check with the hub manufacturer to
be sure the hub supports a device such as a microphone. Plug
the U1 directly into the computer’s powered USB port for
optimal
performance.)
2. Allow 30 to 60 seconds for the system software to recognize
the U1. (A series of bubbles will appear by the Windows
toolbar to notify you of a new device.)
3. In the Start Menu, select Control Panel.
4. Select “Sounds, Speech, and Audio Devices”.
5. Select “Sounds and Audio Devices”.
6. Select the “Audio” tab. Confi rm that under the “Sound
recording” section the “C-Media USB Audio Device” is
selected. (The “Sound playback” should remain your usual
sound output device).
7. Select the “Volume” tab under the Sound recording heading
and select “Advanced Controls” in the Options menu of this
window.
8. Click the “Advanced” button to open the “Advanced Controls
for Wave In” window. Depending upon your system, you
might have the option of selecting “1 AGC” or “Mic boost”.

experience distortion when recording louder sounds, try
unchecking this option.
