2. Enter a value for the microphone height. This distance is between the floor and the microphone height.

3. If necessary, use the orientation tool at the bottom of the workspace to rotate the configuration view to match the installer's perspective. Use the degree

value or the microphone LED in the workspace to confirm the position.

Step 2: Select a Template

Select a template that is the closest match to the seating scenario.

Step 3: Set Coverage

Lobes can be automatically or manually positioned. The Auto Position feature detects sound from a specific area when the microphone has already been installed.

Manual positioning is useful for designers, when the room has been specified but the microphone has not yet been installed.

Automatic Positioning

Automatic positioning determines the talker position (X/Y values) and the talker height through a simple soundcheck.

1. Select a channel to position the lobe.

2. Choose Auto Position in the Channel Properties section to start the process.

3. Follow the directions provided for each step presented in the software.

4. Repeat for each channel as needed.

Best Practices

• Verify that the microphone height has been accurately entered in the Array Properties.

• Use speech as the sound source. Do not use test tones.

• Eliminate noise sources in the room if possible, such as projectors or fans.

• For the best acoustics, talkers should not be directly against a wall or in a corner, as acoustic reflections can reduce aiming accuracy.

• Speak from the exact location where the lobe should be positioned. It is important to match the height (sitting or standing), as talker height is determined

through automatic positioning.

• If a lobe needs to cover an area with multiple talkers, talk from the center of the region. Manual adjustments may be necessary after the lobe is positioned

to ensure the entire area is covered.

Manual Positioning

1. Move lobes to cover the appropriate areas.

⁃ Lobes are independently selectable and can be moved anywhere within the maximum allowed coverage area. If dragged outside of this region, lobes

turn red and revert back to the last acceptable position.

⁃ Lobes can be positioned in two ways: drag them into place, or manually enter a distance from the microphone. Distance values are X and Y along the

grid, with the microphone centered at 0.

⁃ Use the grid to measure the precise placement of the lobe.

2. Enter the talker height by selecting a lobe and providing the value in the Channel Properties. This ensures accurate aiming.

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 talkers 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-axis 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.
