Setting up GLM
A good studio monitor will produce uncoloured , neutral audio – so should have a reasonably flat , smooth frequency response and low distortion . Then , where you position the monitors will have a significant impact on what you hear – with walls , corners and reflective surfaces all having an influence . Genelec ’ s own Monitor Setup Guide provides a wealth of useful information to help you get started .
Then , with Genelec ’ s Smart Active Monitoring family , once you ’ ve got the basics right then GLM loudspeaker manager software takes over .
You place GLM ’ s high quality reference microphone at your chosen listening position , and then GLM sends a frequency sweep through each Genelec monitor in turn . GLM then analyses the sweep and quickly works out how your room is affecting the frequency response , playback level and time delay of the sound reaching you from each monitor .
GLM can then intelligently and automatically compensate for these room effects , by controlling each monitor ’ s internal DSP circuitry to ensure that the sound reaching you from every monitor is consistent in frequency response and playback level , with no time delays between different monitors . This whole process takes just a few minutes , after which you can compare the original and calibrated playback performance to see and hear what GLM is doing .
Making the GRADE
At this stage , you can simply use the automatic calibration settings and start working , knowing GLM has identified and compensated for your room ’ s negative acoustic influences . But you can also choose to manually customise the calibration , since sometimes the best solution is to create a balance between a flat system response and what feels most ‘ natural ’ to your own ears . The choice is yours .
GLM has so many more neat refinements , including the ability to create calibration settings for different listening positions , switching between different monitoring setups and setting calibrated listening levels . GLM ’ s GRADE report has also become a real game-changer .
Within GLM , you can automatically generate GRADE ( Genelec Room Acoustic Data Evaluation ) reports , which give a complete analysis of your room and monitoring system performance , and offer advice on any acoustical issues – helping you to fine tune your room ’ s acoustic treatment , adjust monitor and listener positions , and optimise bass management . No other calibration system offers this level of detailed analysis and support .
A true sonic reference
Hopefully this gives you a neat overview of what GLM does . Genelec has been pioneering loudspeaker calibration technology for decades now , long before it became a widely adopted concept . The advantages of GLM include complete scalability from stereo to complex immersive formats , and fixed , low latency performance without having to bypass any monitoring software sitting on the master audio buss . Additionally , since settings can also be stored within the monitor or subwoofer itself , this avoids the possibility of accidental changes – making GLM perfect for multiuser rooms and demanding production environments .
So , armed with Genelec Smart Active Monitors and GLM , you can create a true sonic reference wherever you choose to work , and produce mixes that translate consistently .
