10.5 _CALIBRATE THE SPEAKERS IN THE ROOM
IMPORTANT NOTE: In order to perform a proper calibration, it is important to carefully read the entire chapters
about the Essential Tools and Settings and Getting Ready for Calibration to learn about the Altitude

audio
clock settings, audio utilities (metering tools, pink noise and solo/mute buttons) and microphone placement
recommendations.
10.5.1 _OVERVIEW OF THE CALIBRATION PROCEDURE
If your speakers have been specified correctly, the calibration process is a relatively
straightforward process:
1. Adjust the master output level to achieve good quality measurements,
2. Start the automated calibration: The Altitude
16
will measure the acoustical response of each loudspeaker in the room;
3. Compute the optimization filters,
4. Save one or more presets with your preferred optimization settings.
10.5.2 _ADJUST THE MASTER OUTPUT LEVEL
To access the calibration page from the Altitude
16
Main page:
Click on the Setting button in the top menu to open the Advanced Settings user interface. Go to the Optimizer Settings/
Calibration page.
The Optimizer requires a minimum Sound Pressure Level for proper calibration. Until that minimum SPL is reached, the
test signal will keep playing through the same speaker. For safety matters, we recommend performing that first calibration
as if it were a test.
Set a safe output leve l:
1. Decrease Master Level to -40 dB;
2. Press the Mute button to cut the outputs (this step must ALWAYS be performed before pressing on the Calibrate button),
3. Press the Calibrate button in the Calibration tab in the Optimizer Settings page of the Advanced Settings interface,
4. Follow the on-screen instructions regarding the microphone: take off the cover and switch it on.
Adjust the output level:
1. Increase the master level until the test signal moves on to the second speaker;
2. Use the Altitude
16
metering tools in the Processor/Meters page to check the level of the microphone inputs,
3. Use your ears to evaluate the perceived SPL of each driver and, if possible, increase the master output level to ensure
that an optimal SPL is reached for all the speakers. This will also improve the quality of your measurements,
4. Use the Cancel button to stop the calibration (optional).
