Reference Level Calibration
The GLM.SE™ allows easy calibration of the monitoring sound level to a standard reference value. This
working method is commonly seen in work destined for theatrical release for TV (85 dB SPL) or radio
broadcast (79 dB SPL).
The reference sound level is displayed on the GLM.SE™ Main Page below the "DIM –20 dB" button. The
default value for this has been set such that a single loudspeaker placed at a 2-meter (6-feet) distance will
produce a sound level of 80 dB SPL with the internal two-octave pink noise generator set to ON.
In order to get a meaningful reading:
•
Run Genelec AutoCal™ to calibrate the Acoustical Settings of the loudspeaker system
•
Run the Reference Level Calibration
In order to calibrate the system reference level

Center is used for multi-channel systems.
•
Turn on the pink noise generator by clicking the "On/Off" button.
