Aligning Subwoofer Phase with GLM AutoPhase
The purpose of the 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.
Figure 17. Steps in running the AutoPhase automatic phase calibration process
The steps to run AutoPhase automatic subwoofer phase calibration include
 connect the calibration microphone to the GLM adapter
 place the microphone at the listening position
 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
 start the AutoPhase measurement process by clicking on the calibration microphone icon
 wait until the AutoPhase calibration is completed
 click ‘Confirm Calibration’ button to accept and save the calibration
 if there are several subwoofers in the group, the AutoPhase will move to the next
subwoofer automatically.
