4 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
management network cables, GLM network adapter, GLM measurement microphone, and GLM 4
software.
To set up a Genelec SAM system,
check DIP switch controls of the SAM subwoofers and monitors. The ‘Stored’ switch,
if available, should be ON when to use the stored settings in the standalone use –
the stored settings come to force when the devices are re-powered up while the
‘Stored’ DIP is set to the right position
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 4 software, www.genelec.com/glm
create a system setup using the GLM 4 software
4.1 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 the 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.
Genelec Loudspeaker Manager (GLM) 4 - System Operating Manual page 10 of 87
Figure 1. Place monitors symmetrically relative to the walls. Point the acoustical axes towards the
listening position.
4.2 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 monitors.
Bass management means using a subwoofer to reproduce low frequencies for any or all of the
audio channels. Audio channels for monitors that are not bass managed can be run directly to the
monitors. They do not need to run to the subwoofer.
When you need both analog and digital audio cabling, it is possible to populate both analog and
digital inputs and outputs on SAM monitors and subwoofers. GLM allows the Group configuration
to select either the analog or digital audio. Note that the 8320 monitor features an analog input
only.
The most common audio cablings are introduced next.
4.2.1 Analog Stereo
Before cabling, turn off the power in all monitors.
connect audio cables from the audio source to the monitor ANALOG IN

Figure 7. Digital stereo adaptive woofer system cabling.
4.2.7 Adaptive Woofer System in a multichannel setup
The adaptive woofer system can be used in any multichannel setup, but there are some
considerations. The adaptive woofer system only is intended to be used with one main monitor,
only.
Connect signals to an additional subwoofer(s) to utilize bass management and to reproduction the
LFE channel.
The full calibration of the adaptive woofer system is in three steps:
1. Run AutoCal for all the main monitors and subwoofer(s)– the woofer systems will not
reproduce any sound in this 1st procedure.
2. Run AutoPhase for the subwoofer(s) against a selected monitor – this monitor is not a
monitor connected to an adaptive woofer system. Typically, a subwoofer is phase aligned
with the Center channel monitor. When a second subwoofer is used for the overhead (toplayer) monitors, this subwoofer is paired with one of the overhead monitors.
3. The adaptive woofer system calibration WooferCal is done last. To calibrate, pair the
adaptive woofer system to a monitor, select the calibration mode and set the crossover
frequencies, and then click the ‘Start Calibration’ button to start calibration.

4.4 Downloading and Installing GLM Software
The GLM software calibrates and controls Genelec SAM systems. The software can be
downloaded at www.genelec.com/glm.
Look for ‘GLM 4 install package’.
In order to download, you will be asked to give your email address and some contact information.
This is very useful as it enables Genelec to support you later. It is not possible to download the
package without a valid email address. You will receive a download link into your personal email.
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 13. GLM software download
GLM requires an Internet connection. The Internet connection is used for the GLM AutoCal
calculations in the Genelec Cloud. GLM AutoCal has been continually improving since its
introduction 2006 and using the Genelec Cloud service ensures you have always access to the
newest, most up-to-date algorithms and tools for calibrating your audio reproduction system.
Genelec Cloud is the default set in the GLM software, Genelec recommends using the Genelec
Cloud for AutoCal as this offers the most accurate calibration.
4.5 Downloading and Installing the local AutoCal calibration
If you are running a computer that never has an Internet connection, it is possible to install a local
calculation needed for GLM AutoCal system calibration. This should be avoided if possible as the
local calibration does not develop and improve automatically as does the standard Genelec Cloud
based GLM AutoCal calibration.
GLM must installed before installing the local AutoCal. The local AutoCal package does not work

The GLM software calibrates and controls Genelec SAM systems. The software can be
downloaded at www.genelec.com/glm. Look for the ‘GLM local AutoCal install package’.
In order to download, you will be asked to give your email address and some contact information.
This is very useful as it enables Genelec to support you later. It is not possible to download the
package without a valid email address. You will receive a download link into your personal email.
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.
Install the package using the defaults in the installation package. Do not modify the install directory
as this will prevent correct operation.
4.5.1 Updating the ‘Mic Serial’ microphone calibration data
The Local AutoCal needs a microphone calibration file for the most accurate calibration result. In
order to obtain the microphone calibration file for your microphone, take the following steps
enter the microphone serial number in the ‘Mic Serial’ field – normally this is automatically
correct as this has been factory-stored inside the GLM Adapter
ensure that the ‘Local AutoCal’ mode is selected
ensure that the computer is connected to the Internet for the next step
run AutoCal once by clicking on the ‘Start Calibration’ – for this have at least one SAM
monitor and the GLM measurement microphone connected to the GLM Adapter
This step accesses the microphone calibration in your computer. After having done this, you can
continue running Local AutoCal without an Internet connection.
If your computer cannot be connected to the Internet even temporarily, please contact Genelec
customer service (https://support.genelec.com/hc/en-us/requests/new) and ask for your GLM
measurement microphone calibration file for the Local installation of GLM. We will email the file to
you. Replace the field <your_username> with your actual user name.
Copy the microphone calibration file into this folder in the Mac OS computer:
/Users/<your_username>/Documents/Genelec/GLM4/DSP/Microphone
Copy the microphone calibration file into this folder in the Windows computer:
C:\Users\<your_username>\Documents\Genelec\GLM4\DSP\Microphones
After this you can run the Local AutoCal calibration without having a connection to the Internet.
Please note that when you are running the Local AutoCal there is no way for Genelec to offer you
updates to the software you are running, including the Local AutoCal calculation algorithms.

5 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 SAM monitoring group
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)
5. run GLM WooferCal automatic calibration for woofer system (WooferCal is only available
when an adaptive woofer system is included in a group)
For additional groups, repeat steps 2 - 5.
5.1 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 14 shows a
stereo system with a subwoofer.
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 creating a new layout, initially all monitors, subwoofers and woofer systems are stacked
in the ‘UnPlaced’ cell, on the left side of the page.
Select the large enough layout grid to place all your monitors. Use the ‘Layout Style’ to change
and select a placement template. If you do not find a template suiting your system, select a grid
size that has place for all monitors, subwoofers and woofer systems.
The ‘Reset Layout’ button clears the layout grid and sends all the monitors and subwoofers back
to the ‘UnPlaced’ cell. This allows you to do the placement again from the start.
