Dayton Audio's OmniMic V2 was developed in collaboration with Liberty Instruments, inventors of the Praxis analysis tool. Powerful, versatile, yet easy to use, the OmniMic V2 Precision Measurement System will become an indispensible part of your audio toolbox—whether for testing individual speaker components or entire in-place audio systems of every description. The OmniMic V2 provides quick and accurate measurements that will reduce installation time, saving you both labor and money.

The OmniMic V2's test signals may be initiated from the host computer, or from any audio CD player. System includes calibrated USB microphone, rubberized mic clip, software and test signal discs, 6 ft. USB 2.0 cable, desktop tripod stand, and carrying case. Compatible with Windows XP, Vista, Windows 7, Windows 8, and Windows 10.

Note:Windows 8 users Windows 8 has a USB recording bug. To get around this issue and use the OmniMic on a machine using Windows 8, please perform the following:

Find the OmniMic icon, Start Menu entries, etc., that you use to start the OmniMic software. Instead of left-clicking the icon, right-click and then left-click on the "Properties" menu item. A "Properties" window should open. Select the compatibility tab and find a checkbox labeled "Run this program in compatibility mode for:" There is a drop-down box just below the checkbox, set that to "Windows XP (Service Pack 3)". Then put a check in the checkbox and click "Ok" to close the properties windows.

Now whenever you start OmniMic using that icon (or menu item), it will run in the XP mode that avoids the Windows 8 USB recording bug.
