Step 1: Set Microphone Properties
1. Set the Units to feet or meters, according to your preference.
2. Enter a value for the microphone height. This distance is between the floor and the microphone.
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 posi
tion.
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 sound
check.
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 re
duce 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 micro
phone. 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.
