5.4 Aligning Subwoofer Phase with GLM AutoPhase

The purpose of GLM AutoPhase is to set the subwoofer phase at the crossover frequency in
relation to a selected monitor so that the combined response of the subwoofer-monitor system is
flat across the crossover region.
The steps to run AutoPhase automatic subwoofer phase calibration include
1. Define the monitor to be aligned with the subwoofer by single clicking on the subwoofer
icon first and then the monitor icon; this is done for each subwoofer in the group; if there
are several subwoofers in the group, associate every subwoofer with a monitor before
proceeding to the AutoPhase calibration. The 'Pair' text with number will show the paired
subwoofer and monitor.
2. Connect the calibration microphone to the GLM adapter, place the microphone at the
listening position, at ear height, and start the AutoPhase measurement process by clicking
on the 'Start Calibration' button. Wait until the AutoPhase calibration is completed.
3. Click 'Confirm Calibration' button to accept and save the calibration to the setup file.
If there are several subwoofers in the group, the AutoPhase will move to the next subwoofer
automatically.
