Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 6 of 52 System Components SAM Monitors Smart active monitors (SAM) are supported on Genelec’s GLM control network. Genelec has a very large selection of SAM monitors, ranging from compact two-ways to large three-way main monitors. SAM Subwoofers Smart active subwoofers are supported Genelec’s GLM control network.
Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 7 of 52 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 2.0 software.
Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 8 of 52 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.

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.

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.

Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 45 of 52 Stand-Alone Operation SAM monitors and subwoofers are set up and calibrated using GLM control network and GLM 2.0 user interface software. 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.
Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 46 of 52 Connecting the GLM Volume Controller The volume controller is connected to the GLM adapter via 3.5 mm jack showing a level control triangular sign. See the bottom of the GLM adapter for more information. Caution: Be sure to turn the volume controller fully counter-clockwise (level down) before connecting the volume controller to the GLM Network Adapter. Figure 28.

Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 50 of 52 Frequently Asked Questions Why do ID tones vary in different system configurations? Different SAM monitors generate different identification tones. The identification tones are listed in the table below. Table 14.
Genelec Loudspeaker Manager (GLM) 2.0 - System Operating Manual page 51 of 52 Can analog and digital signal sources be mixed? Yes and no. One type of signal can be used in one group. However, it is easy to create two groups, one for analog input and another for digital audio input. After this, switching from one group to the other will select the input signal type. How to switch between analog and digital signal? Groups can be defined to select analog or digital input signal.
