    (SAM) system it is important to become familiar with all the components in the system. More detailed informa- tion can be found from the GLM 4, monitor and sub- woofer operation manuals. To set up a monitoring system you will need monitors...
  • Page 4 Figure 1. Place monitors symmetrically relative to the walls. Point the acoustical axes towards the listening position. To set up a Genelec SAM system • Check the dip switches of the SAM subwoofers and monitors. The ‘Stored’ switch need to be turned ON if storing the settings to the SAM subwoofers and monitors for standalone use.

    3.5 DOWNLOADING AND INSTALLING GLM SOFTWARE The GLM software calibrates and controls Genelec SAM systems. The software can be downloaded at www.genelec.com/glm. You must have sufficient rights to install the software in your computer. Install the software following the instruction given by the software during the installation process.

    5. The monitor already placed to the layout grid. 6. The layout confirmation button – Click to proceed after the layout matches the actual monitoring system layout. 7. The setup process indicator – AutoPhase will be skipped if there is no any subwoofers in use and WooferCal will be skipped if there is no any Woofer systems in use.

  • Page 12: Automatic Calibration

    3.9 AUTOMATIC CALIBRATION 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 the WooferCal page after the AutoCal and AutoPhase stages.
  • Page 13 To calibrate a monitoring group 1. Check the serial number of the measurement micro- phone (measurement microphone calibration file is retrieved during first calibration) 2. Select the calibration mode; either a single location measurement (SinglePoint) or measurements of multiple measurement positions (MultiPoint). Select the Symmetrical EQ if a Left/Right pair of monitors should receive the same calibration filters.

    Figure 7. Steps in running the AutoCal automatic system calibration process. 3.10 ALIGNING SUBWOOFER PHASE 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.

    3. Click the ‘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. Figure 8. Steps in running the AutoPhase automatic phase calibration process.
  • Page 16 Continued directivity, or one of the three directivity null modes. Each calibration mode or setting will require an individual group to be created. 3. The parameters for setting the search limits for the crossover to the main monitor should then be set. These controls are available for all modes except the Continued directivity mode, where the crossover value is fixed based on the main monitor connected in the pairing.

    3.12 BASIC USE OF GLM 1. System level. 2. Selection and activation of group presets. 3. Mute, mute all. 4. Dim (-20dB). 5. Standard loudness SPL level (calibration from ‘Group Preset : Standard Loudness SPL Calibration’ menu). 6. Level preset selections (to set adjust the system level at desired level and click ‘Group Preset : Set Preset Levels : Set Current Level to Preset1).

  • Page 19 Follow these steps: 1. Open GLM4 main page (at least one setup with GLM4 must be created) 2. Click ‘File : Import GLM3 Setup…’ menu. Figure 11. Import GLM3 Setup-menu. 3. Select a GLM3 setup file to be imported and click ‘Open’.The imported setup will be stored with the same name to GLM4.

  • Page 20: Standard Loudness Spl Calibration

    4.2 STANDARD LOUDNESS SPL CALIBRATION The Standard Loudness SPL feature allows calibration of the listening level in accordance with digital loudness standards such as ATSC A/85 and EBU R128. Calibrated listening level is important to judge speech intelligibility, spectral balance, platform compatibility etc. The in-situ frequency response compensation and sys- tem alignment should be followed by the absolute SPL listening level calibration.

    • Select level calibration standard from the dropdown list. • Place the Genelec calibration microphone at the listening position. • Click the ‘Start Calibration’ to start the calibration process. Note that the test signal may be loud. If the background noise in the room is more than 65 dB SPL, the loudness preset cannot be calibrated.

    brighter, the Sound Character Profiler found in the Group Preset menu is a quick place to start. There are Profiler Presets including the Manual option. Setting the Profiler uses two shelving filters in all monitors in the selected Group. The Sound Character Profiler tool (SCP) can be accessed via the ‘Group Presets | Sound Character Profiler’...

Settings that are stored; The Current Group Acoustic Settings, Startup Level, ISS Power Saving settings, LED Disable and Input Mode. Figure 16. Store Group Settings page ISS support is not available for the following products: 7260A, 7261A, 7270A, 7271A, 8240A, 8250A, 8260A.
