you must confi rm that the computer’s operating system recognizes the U7 

microphone.

Windows XP recognition instructions

1.  Plug the U7 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 microphone 

directly into the computer’s powered USB port for optimal performance.)

2.  Allow 30 to 60 seconds for the system software to recognize the U7. 

(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”. Checking this option will 

 signifi cantly increase the sensitivity of the microphone. Use this for 

recording softer sounds. If you experience distortion when recording 

louder sounds, try unchecking this option.
