Genelec Loudspeaker Manager (GLM) 3 - System Operating Manual page 8 of 73
Getting Started
To take full advantage of your Smart Active Monitoring (SAM) system it is important to become
familiar with all the components in the system.
To set up a monitoring system you will need monitors and subwoofers, audio signal cables, GLM
control network cables, GLM network adapter, GLM measurement microphone, and GLM 3
software.
To set up a Genelec SAM system,
place SAM subwoofers and monitors in the monitoring room
run audio cables to the SAM subwoofers and monitors
run GLM network cables from the GLM adapter to all SAM subwoofers and monitors
download and install the GLM computer software
create a system setup in the GLM software
Placing SAM monitors and subwoofers in the monitoring room
Try to place monitors and subwoofers in optimum locations in relation to surfaces reflecting audio.
Aim each SAM monitor towards the listening position. This becomes your System Layout.
1. Select listening position so that distances from side walls (B) are equal.
2. Place monitors so that distances to the listening position are equal, and distances to the
monitors are equal from side walls (A).
3. Place a subwoofer at the front wall and a slightly left or right from the room centre axis.
4. Aim monitors towards the listening position.
Figure 1. Place monitors symmetrically relative to the walls. Point the acoustical axes towards the
listening position.
Genelec Loudspeaker Manager (GLM) 3 - System Operating Manual page 9 of 73
Cabling for Audio Signals
Run all audio cables from the audio source to the monitors. When a subwoofer is used, run the
same signal to the monitor and the subwoofer. We recommend running the signal to the subwoofer
first. The subwoofer has output connectors to facilitate onward connection to the monitor.
Those audio channels that are not going to be bass managed can be run directly to the monitors
and do not need to run to the subwoofer. Bass management means using a subwoofer to
reproduce the low frequencies for any or all channels.
When you need both analog and digital audio cabling, it is possible to populate both analog and
digital inputs and outputs on SAM products. GLM allows Group configuration to be either analog or
digital. Note that the 8320 features analog input only.
The most common audio cablings are introduced next.

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. We recommend you
install the software on the local hard drive. There is no need to make any special destination
folders, GLM creates these automatically.
Figure 11. GLM software download
Creating a System Layout and Calibrating a System
Before launching the GLM software after installation, stop or mute the audio source, ensure that all
monitors and subwoofers are connected to the GLM network and are powered on.
The steps to create a GLM System Setup with a system layout and calibration are
1. create a SAM monitoring system layout
2. define one or more SAM monitoring groups
3. run GLM AutoCal automatic calibration
4. run GLM AutoPhase automatic phase calibration for subwoofers (AutoPhase is only
available when a subwoofer is included in a group)
Creating a SAM Monitor Layout
To create a layout all monitors and subwoofer must be powered and GLM network connections be
made.
A layout defines your monitors and their locations in the room. An example in Figure 14 shows a
stereo system with a subwoofer. On the left you see the GLM layout definition page and on the
right you see the actual monitoring system in the room.
A new system layout is created when the GLM user interface starts the first time. You can always
create a new layout by selecting the ‘File | New’ menu item.
When the creation of a new layout starts, initially all monitors and subwoofers are stacked on the
left side of the page.
Genelec Loudspeaker Manager (GLM) 3 - System Operating Manual page 20 of 73
Figure 12. Drag and drop the monitor icons onto the layout grid to build a system layout
Use your mouse to drag and drop monitors or subwoofers onto the layout. Drag a monitor or
subwoofer icon from the stack to the layout grid on the right and drop it to the position that matches
its position in the room. Continue this until the stack is empty.
Note: monitors and subwoofers are automatically named by the location information, e.g. when the
monitor is dropped on the left side, it is named as ‘Left 8330A’. If a monitor has AES/EBU digital
input it will also get a default AES/EBU subframe to be reproduced in the digital group, e.g. when
the monitor is dropped to the left side, it gets subframe A selected as default. In the acoustic
calibration the placement information is used to define front left/front right monitor pairs for the
equal room filter designs. The equal room filter design is possible when front left and front right
monitors are placed symmetrically to the grid (see Figure 13) and checking the ‘Each front Left-
Right pair shares the same equalizer settings’ box in the acoustic calibration page.
Figure 13. An example of an empty monitor stack
When you drag, the real monitor plays an identification tone and flashes the front panel LED. The
identification tones depend on the SAM product type and the tones can vary between products in
the same setup.
After all monitors and subwoofer have been moved to the layout, click on the ‘Confirm Layout’ to
continue.
Genelec Loudspeaker Manager (GLM) 3 - System Operating Manual page 21 of 73
Figure 14. The steps of creating a SAM system layout
The additional display box ‘Not used in this setup’ is primarily used with Small Environment (SE)
systems (SE7261). It defines the number of unused 8130s with the SE7261 subwoofer.
For example, the SE7261 can support up to 8 x 8130s and the system setup starts with 8 SE
channels on the Stack. They are labeled 1A, 1B all the way through 4B. However, if your SE
system only has 2 channels being used in input/outputs 1 for stereo (1A and 1 B), you would take
the next 6 (2A thru 4B) off the Stack and place them into the “Not used in this setup” bin.
Note: any SAM monitor that is placed into the “Not used in this setup” bin (Figure 15) cannot be
used as part of the current Setup and in creating other Groups. You will need to create a new
Setup using the File/New syntax in order to use them.
Figure 15. Location of the 'Not used in this setup' bin.
Genelec Loudspeaker Manager (GLM) 3 - System Operating Manual page 22 of 73
Creating a SAM Monitor Group
A SAM monitoring group is a set of monitors and subwoofers that reproduce audio together. A
group contains settings that can optimize every monitors and subwoofers.
To define a monitoring group:
give the group a name (1) that describes it (e.g. Analog Stereo)
select the input signal (2) for the group (Analog or AES/EBU)
click on each monitor and subwoofer, then edit/check the setting (3) (for more information,
see the GLM Advanced Settings); the monitor with a green halo is active; monitors with
yellow halo are not part of the group
confirm the group settings by clicking on the ‘Confirm Group’ button (4)
For more detailed information on using and setting up Groups, see the section ‘GLM Advanced
Use’.
