Since its introduction, the GLM software application has helped audio professionals on both Mac and PC to configure, calibrate and control their Genelec monitor systems, delivering fully optimised performance for their acoustic environment. GLM 3 now offers beta Cloud services, Reference Level listening features and several other important refinements – making it the most powerful version of GLM yet!
GLM Software

If you’ve ever been frustrated that your mixes don’t translate well to other systems, it’s because your monitors and your room are interacting to produce a frequency response that can be far from the neutral and smooth response that you need to create a great mix.
GLM 3 software tightly integrates with the advanced internal DSP circuitry which a growing family of Genelec SAM monitors and subwoofers is equipped with, from the tiny 8320 to the massive 1236A. GLM 3’s reference microphone kit allows your acoustic environment to be analysed, after which GLM 3’s AutoCal feature optimises each monitor for level, distance delay, subwoofer crossover phase and room response equalisation, with the option for you to further fine tune the system. By minimising the room’s influence on the sound, GLM 3 helps Genelec monitors deliver an unrivalled reference, with excellent translation between rooms.

Whether you’re a new Genelec SAM user - or you’re an existing user who wants to upgrade to the latest version - then GLM 3 is a free download, available via the links below.
Please note that to enable GLM software to integrate with your SAM monitors, you’ll also need the Genelec network adaptor kit (8300-601) – which includes the GLM network adaptor, 8300A calibration microphone and microphone holder, 1.8 m USB cable and Quick Connection Guide. The network adaptor connects to your Mac or PC via the supplied USB cable, and to your SAM monitors via an 5 metre Ethernet cable (which is supplied separately with each SAM monitor).

Knobloch – noted for his skillful touch with critical music choices for major films including the Fifty Shades of Grey and Fast & Furious franchises, Pitch Perfect, Straight Outta Compton and more –relies on Genelec Active Monitoring for various music and film projects.
Mike Knobloch, President of Global Film Music and Publishing for Universal Pictures since 2010 (after 13 years as EVP of music at 20th Century Fox), knows what it takes to create the critical nexus of movies and music, and that’s what he’s done for dozens of major motion pictures. The GRAMMY®-nominated producer, music supervisor and studio executive’s soundtrack portfolio includes the hit franchises for Fifty Shades of Grey, Fast & Furious, Pitch Perfect, Despicable Me and Jurassic World, along with blockbusters Les Misérables, The Bourne Legacy and Sing. Holiday movie-goers in 2018 also experience his work with Danny Elfman and Tyler, The Creator on the blockbuster animated production of The Grinch. Through all of it, tying Mike Knobloch’s musical work together is the use of Active Monitoring from Genelec.
Knobloch’s office on the Universal Pictures lot in Universal City, California, is currently home to three sets of Genelec monitoring systems: a pair of 1032C Smart Active Monitors™ and a Genelec 7370A Smart Active Subwoofer™ are on stands on either side of the flat-panel video display in his office; a pair of 8330A Smart Active Monitors and a 7350 Smart Active Subwoofer are at his desk; and two 1237A Smart Active Monitors and a 7380 Smart Active Subwoofer fill the office’s conference room.
“I spend an enormous amount of time in music studios, post studios, high-end recording studios and dubbing stages,” says Knobloch. “You get to know the brands and the trends in monitoring, and Genelec speakers are the ones that are the common thread through all of them. They’re the most accurate, reliable monitors out there. No bells, no whistles, just accurate sound. In this business, you have people zapping audio files around all the time, looking for notes and input on songs and mixes, and mixes are done all over the place. Having Genelec everywhere in every critical monitoring environment that I use everyday means that I get a consistent listening experience in every room. Genelec is an industry standard, and that brings peace of mind.”
Knobloch also appreciates the technology that accompanies the Genelec speakers. For instance, in his office, the 1032C speakers (as well as all the other Genelec systems on site) employ the proprietary GLM™ 3 software, which tightly integrates with the advanced internal DSP circuitry, allowing acoustic analysis and optimization for the room. By minimizing the room’s influence on the sound, GLM 3 helps Genelec monitors deliver an unrivalled reference, with excellent translation between rooms. “The 1032s are tuned for me at my desk, but if I have visitors in for meetings, I can change the sound field to focus on another part of the room, so everyone gets accurate imaging,” he says. “Using GLM has become second nature to me now.” Knobloch’s 1032s are connected to an Apogee Duet interface with his Apple Mac Pro, providing a premium monitoring solution for A/Bing streaming tracks and works-in-progress. And in the conference room, the Genelec 1237 speakers easily cover the 30 or so people it can accommodate. “It could be a movie mix or a television show theme song, everyone hears what the producers intended,” he says.
Currently, all of Knobloch’s Genelec monitors are getting a workout as he collaborates with three-time GRAMMY® Award nominated producer Harvey Mason, Jr., on music for the sequel to the 2016 film hit Sing, a budding franchise he calls “a love letter to music.” “It has so many music moments,” he says, “and you want to make sure you hear every nuance of each one. And Genelec makes sure that I do.”

The Genelec Loudspeaker Manager (GLM™) Package provides all necessary components to establish connectivity to SAM™ monitors. Complete network system setup and control of up to 30 monitors and subwoofer is possible via a standard CAT5 or CAT6 cabling.
The GLM™ includes simple to use step-by-step setup wizards to ensure a pain-free and thorough installation, access to extensive Acoustical Settings in each monitor, and System Setup files for saving and recalling of all settings.
As an essential part of the GLM software, GLM™ AutoCal is a fully automated acoustical calibration tool for a single room multi-monitor system which combines decades of acoustic research along with our proprietary DSP and network control. The AutoCal system produces monitor-generated test signals recorded by a calibration microphone to determine correct acoustical alignments for every monitor and subwoofer on the GLM control network.
The differences are in the steepness of the crossover filters and the slightly tighter on-axis response. When using the GLM™ control network and AutoCal, the monitor can be integrated into the room with greater precision and the differences may be significant.
Software updates and upgrades will be clearly announced on the Genelec web site.

Setting Up Your Speakers

How To Select The Correct Monitors
A monitor, by definition, observes, checks, controls, warns or keeps a continuous record of something. An audio monitor, studio monitor or monitoring speaker is more than just a good-sounding loudspeaker. It is a device used in the process of recording, mixing or broadcasting audio in any environment where accurate listening is needed. A monitor is a professional tool.

How To Place Your Monitors
To create the ideal listening experience, several aspects need to be taken into account when placing the monitors within the listening space. First, you need to identify the listening area within the space and consider where the listener will be placed in relation to the space as well as the studio monitors. These will be influenced by the wall reflections and radiation space around the monitors. With careful planning, your monitor placement will help you enjoy the best possible listening experience!

Monitor Calibration & Improving Acoustics
The acoustic environment of the listening space has a major influence on the sound quality. Walls, ceiling, and floor as well as large objects like mixing consoles, tables, equipment racks, and furniture cause reflections.
