Using the Reference Grid
The grid provides a frame of reference to show distances relative to the center of the microphone. The selected
unit (feet/meters) applies to the grid, so make sure it has been set appropriately. If the distances between the talk
ers and the microphone are known, the grid can visually verify that the lobe placement is correct.
Note: Values to the left of the microphone on the horizontal Xaxis, and below the microphone on the vertical Yax
is are measured as negative values. When the rotate feature is used, the grid values change to match the new
perspective.
Adding and Removing Channels
To add channels into the workspace, use the Add Channel button located above the workspace.
To remove a channel, select a lobe and select Remove Channel, located under the Channel Properties. The delete
key may also be used to remove the selected channel.
