the audio source is set using the osprey-210/220’s mixer driver interface. most applications, including the windows media encoder applications, interface to the mixer driver directly and expose the look and feel specific to that application. however, the default windows interface to the mixer driver can also be used. there are two simple methods for getting to the mixer source

    and volume control dialog box.

   

    1. the easiest method for accessing this interface is to right click the speaker symbol on your taskbar (typically on the bottom right-hand side of your screen). then select the open volume controls option.

    2. if you do not see the speaker symbol, click the start button on the start menu,select programs-]accessories-]entertainment (or multimedia) and select volume control.

    either of these two methods brings forth the audio mixer interface for the audio playback device. to get to the osprey-210/220 audio capture (recording) device,select properties under the options menu. this pops up a dialog to select the mixer device. do not select the recording option within the adjust volume for section; this option is selected automatically when you select the osprey-210/220 for the mixer device. click on the dropdown list for mixer device to see the list of audio input and output devices, including the osprey-210/220.

   

    if more than one osprey-210/220 card is in the system, each osprey-210/220 card is enumerated individually. once an osprey-210/220 device has been chosen, select ok in the properties dialog box.

    the osprey-210/220 master control panel displays.

   

    the osprey-210/220 device is not a mixer in that it does not allow for mixing thevarious audio sources. therefore, when one audio input is selected, any other inputpreviously selected becomes unselected. the select checkbox at the bottom of eachsource sets which source is actually being used.

    the osprey 210-220 has hardware gain control. to control the hardware gain for the osprey-210/220 use the volume slider in the mixer applet. the unity gain setting is when the volume slider is in approximately the middle of the range.

    the quick-access volume control (left click on the speaker symbol) on the task bar controls playback volume and recording volume. to change record levels, go to options, then properties, and select recording.
