3 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. More detailed information can be found from the GLM 4, monitor and subwoofer operation manuals.
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 computer with GLM 4 software.

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. Other controls are not
active when using the stored settings.
• Place SAM subwoofers and monitors in the moni-
toring 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 within the GLM software.
3.1 PLACING MONITORS IN THE MONITORING ROOM
Try to place monitors and subwoofers in optimum locations in relation to surfaces reecting audio, see Figure 1.
Aim each SAM monitor towards the listening position.
This becomes your System Layout. More info about the
correct monitor placement is available at www.genelec.
com/monitor-placement
1. Select listening position so that distances from side
walls (B) are equal.
2. Place monitors so that distances to the listening posi tion are equal, and distances to the monitors are
equal from side walls (A).
3. Place any subwoofers at the front wall, and slightly
left or right from the room centre axis.
4. Aim monitors towards the listening position.
3.2 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 rst. The
subwoofer has output connectors to facilitate onward
connection to the monitors.
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
conguration to be either analog or digital. Note that
the 8320 features an analog input only.

3.3 ANALOG STEREO WITH A SUBWOOFER
Before cabling, turn off the power in all monitors and
subwoofers.
• Connect (Left) audio cable from the source to the
subwoofer connector ANALOG IN 1.
• Connect a cable from subwoofer ANALOG OUT 1
to left monitor ANALOG IN.
• Connect (Right) audio cable from the source to
subwoofer ANALOG IN 2.
• Connect (Right) audio cable from Subwoofer
ANALOG OUT 2 to right monitor ANALOG IN.

3.4 CABLING OF THE CONTROL NETWORK
The GLM control network cabling is very easy. Connect
the GLM adapter to the computer USB port using the
supplied USB cable. Connect the GLM adapter to all
SAM monitors and subwoofers in daisy-chain fashion
(Figure 3) using the network cables supplied with each
monitor and subwoofer. You can connect in any order.
Just be sure to connect all monitors and subwoofers.

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 sufcient 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.

3.6 CREATING SYSTEM LAYOUT AND CALIBRATING
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. Dene SAM monitoring group preset.
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
8
system (WooferCal is only available when an adaptive
woofer system is included in a group).
For additional groups, repeat steps 2 - 5.
3.7 CREATING SAM MONITOR LAYOUT
To create a layout all monitors, subwoofers and woofer
systems must be powered and GLM network connections must be made.
A layout denes your monitors and their locations in the
room. Place Left and Right monitor pairs symmetrically
to the grid to be able to use the automatic symmetrical
room response calibration. Figure 5 shows a stereo
system with a subwoofer.
A new system layout is created when the GLM user
interface starts the rst 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, subwoofers and woofer systems are stacked
on the left side of the page.
1. The layout style selection – shows example positions
for each system (example positions can be skipped
e.g. subwoofer can be placed between Left and
Right monitors).
2. The devices – the UnPlaced device cell on the right
and the Not Used device cell on the left. Start to drag
the device icon from the UnPlaced device cell and
the device will play the ID tone. Place the device
icon to the Layout grid (3) to the position that matches
its placement in your monitoring system layout.
3. The Not Used device cell. This will be used e.g. with
the SE System where GLM needs to know the
unused channels.
4. The layout grid – the monitoring system layout style
with the Stereo with subwoofer system. The center
cell is the listening position (will be placed with the
VOG monitor in an Auro3D system). The top cells
of the grid are the front monitors and the bottom
cells are the rear monitors.
