  • Page 8: Creating A Sam Monitor Layout

    Creating a SAM Monitor Layout To create a layout all monitors, subwoofers and woofer systems must be powered and GLM network connections be made. A layout defines your monitors and their locations in the room. An example in Figure 5 shows a stereo system with a subwoofer. A new system layout is created when the GLM user interface starts the first time.
  • Page 9 Figure 5. Drag and drop the monitor icons onto the layout grid to build a system layout. Creating a Group Preset A group preset is a set of monitors and subwoofers that reproduce audio together. A group preset contains input and acoustic settings to optimize all monitors and subwoofers active within the group.

  • Page 11: Automatic Calibration Using Glm Autocal

    Automatic Calibration Using GLM AutoCal GLM AutoCal is a powerful monitoring system calibration algorithm running in the Genelec Cloud. Sweeps are generated by each monitor in a group. Responses are recorded with the GLM measurement microphone into your computer. NOTE: Adaptive Woofer Systems will be calibrated in WooferCal page after Autocal and Autophase.
  • Page 12 Each setup file can contain several monitoring group preset definitions each with different AutoCal calibration settings. Even with the same set of monitors you can determine several listening positions by applying calibration in several locations and defining each location as a new group preset.

    Figure 7. Steps in running the AutoCal automatic system calibration process 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.

    After SPL calibration, the main page shows the preset levels in dB SPL units, and the Level Preset 1 is set at the standard level, e.g. 73 dBSPL for EBU R128. (Notice the graphical link-line between the Cal. Level and Level Preset 1 keys). To remove the Standard SPL calibration open the calibration page and select ‘Remove Calibration’...
  • Page 20 After setup, monitors, subwoofers and the GLM adapter can also operate without having a computer connected to the GLM adapter. This is called stand-alone operation. SAM monitors and subwoofers retain their settings after storing the settings inside the monitors and subwoofers. In some models the ‘Stored Controls’ switch need to be turned ON to make monitor to use stored settings in stand-alone mode.
