Preliminary setup with Windows 10
If you are using an older version of Windows, your computer will automatically
recognize the USB device and install the appropriate driver.
The first time you plug the microphone in, you may see a message that new
hardware has been found, or you may see a driver software installed notice.
After the first time, you will not see any of these as the computer has already
installed the necessary drivers for a USB microphone.
When the BL-2021USB microphone is connected, Windows 10 will automatically
select it as the input device.
-
To verify or make changes click the Start window and click settings (the gear).
-
When the settings window opens, Click “System.”
-
When the System window opens, in the left column, click “Sound.”
-
The Sound tab opens showing the active input device which should be the USB microphone.
To use the computer speakers as your output device, click “Choose your output device” and in the drop-down menu choose the desired item.
At this point, your computer is set up to use the BL-2021USB microphone as the
audio input device and whatever you chose as the audio output device. However,
in the recent versions of Windows 10, Microsoft has instituted some additional
privacy settings, allowing users to control which apps and programs have
access to the microphone. Refer to the section on privacy for more
information.
There are additional settings available for the microphone, allowing you to
set the input level, change the sampling rate and manage other aspects of the
audio. Refer to the next section for more details.
At this point Windows 10 is set up to use the BL-2021USB microphone as the input device. The sample rate is set for the Windows default (44.1 KHz CD Quality). However, additional settings are available, including input level and sampling rate.
-
To access these settings, click “Sound Control Panel.”
-
When the Sound Control Panel opens, select the “Recording” tab and select the BL-2021USB microphone.
-
Click “Properties.”
-
Click the Levels tab and move the slider to the right or left to set the input gain for the microphone. Setting it too low will not provide enough signal to your recording application. Setting it too high can cause the recording application to distort.
Note that this level setting is different from the volume control slider on the main sound settings window.
