Active Crossovers
Networked Smart Active Monitor (SAM™) Systems feature automatic calibration to the environment.
The last decade has experienced a rapid increase in global media content creation, resulting in significant changes in the way network facilities deal with increased workload. Now, more than ever, a growing number of audio productions are done in tighter, more confined working environments. This increases acoustic problems and lowers the reliability of monitoring. At the same time, a professional audio engineer needs to have high confidence in a reliable and precise monitoring system that reproduces sound neutrally and without distortion.
Built upon the solid electro-acoustic foundations of the 1200, 8000 and 7000 Series products, Genelec advanced SAM Systems are today’s most advanced and flexible monitoring solutions. They are an indispensable tool for audio professionals, as they are capable to automatically adapt to the acoustic environments and correct for levels, delays and room anomalies. SAM Systems can be controlled via Genelec proprietary Loudspeaker Manager (GLM™) network and software, enabling you to build a highly flexible and reliable monitoring system.
The GLM 3 software is a highly intuitive and powerful monitor control networking system that manages connectivity to all SAM studio monitors and subwoofers on the network – up to 30. The GLM 3 software features adjustment of levels, distance delays and flexible room response compensation equalization with the state-of-the-art and robust AutoCal™ automated calibration system. All parameters and settings are stored in system setup files or saved in each individual monitor or subwoofer if the GLM network needs to be disconnected.
Also, all acoustical features of SAM Systems can be optimised for different working styles or client demands. Additionally, even if the monitors or the production projects move between rooms, you can expect SAM technology to achieve the highest consistency in monitoring, providing a neutral sound stage imaging with low distortion.
Genelec SAM Systems offers a comprehensive, solution-oriented, intelligently networked product range supporting analogue and digital signals in virtually any working environment.
Each transducer is driven by its own optimized amplifier.
Audio electronic crossovers allow to split the audio signal into separate frequency bands that can be separately routed to individual power amplifiers which then are connected to specific transducers optimized for a particular frequency band.
In a typical 2-way loudspeaker system, the active crossover needs two power amplifiers — one for the woofer and one for the tweeter. The power amplifiers are connected directly to the drivers of an active loudspeaker, resulting in the power amplifier’s load becoming much simpler and well known. Each driver-specific power amplifier has only a limited frequency range to amplify (the power amplifier is placed after the active crossover) and this adds to the ease of design.
The active design principle offers multiple benefits:
- The power amplifiers are directly connected to the speaker drivers, maximizing the control exerted by the power amplifier’s damping on the driver’s voice coil, reducing the consequences of dynamic changes in the driver electrical characteristics. This may improve the transient response of the system.
- There is a reduction in the power amplifier output requirement. With no energy lost in the passive crossover filter components, the amplifier power output requirements are reduced considerably (by up to 1/2 in some cases) without any reduction in the acoustic power output of the loudspeaker system. This can reduce costs and increase audio quality and system reliability.
- No loss between amplifier and driver units results in maximum acoustic efficiency
- Active technology can achieve superior sound output vs. size vs. low frequency cut-off performance
- All loudspeakers are delivered as a factory aligned system (amplifiers, crossover electronics and enclosure-driver systems)
Intelligent Signal Sensing (ISS™) for power consumption reduction in stand-by mode.
Introduced early 2013, Genelec’s Intelligent Signal-Sensing technology has been developed to meet with both European Union ErP Directives and the company’s own wider sustainability commitments.
The Intelligent Signal Sensing, ISS™ circuitry tracks the signal input of the loudspeaker and detects if it is in use. If the ISS circuit does not find any audio on the input for a period of time, it sets the loudspeaker to a low-power sleep state and the loudspeaker will consume less than 0.5 watts. When an input signal is detected, the loudspeaker immediately turns itself on. Basically, the loudspeaker system will start saving power as soon as work is interrupted.
Additionally an ‘ISS Disable’ switch is located on each product’s back plate next to the other room response controls. First, when the mains power switch of the loudspeaker is set to “ON”, the ISS™ auto-start function (low-power sleep state on/off) of the loudspeaker is active.
If this function is not desired, the ISS™ function can be disabled by setting the “ISS Disable” switch on the back panel to “ON” position. In this mode, the monitor is only powered on and off using the mains power switch.
Note that the mains power switch will always turn the monitor off completely.
Bass Management System handles multichannel low frequency content.
The principle of bass management is that the bass content of the main channels and the Low Frequency Effect (LFE) channel are directed and reproduced only by loudspeakers capable of handling them, whether they are main system loudspeakers or one or more subwoofer(s).
In stereo reproduction, signals from 20 Hz to 20 kHz need to be replayed. Large multi-way monitoring systems will reproduce such a wide bandwidth evenly. With multichannel audio, professional and consumer audio systems must also be able to reproduce audio between 20 Hz and 20 kHz for each channel. To achieve this, main monitors, subwoofers and crossover electronics should work together.
A Bass Management system uses either analogue electronic circuitry or software based filtering which will filter low frequency information from the main channels and route that information to one, or more, subwoofer feed.
The dedicated LFE channel can also be monitored via that subwoofer and added to the low frequencies of the other main channels. Therefore, the Bass Management’s basic and main goal is to ensure that the entire audio bandwidth of all channels can be accurately monitored.
The benefits of the Bass Management System:
- The subwoofer extends the system frequency response down the lower limit of the audible range
- Monitor can produce a higher maximum sound level when not reproducing low frequencies
- Optimized low frequency reproduction by selecting adequate subwoofer location; monitors can also be placed more freely
- Subwoofer’s output are aligned in level and phase with monitors allowing flat and accurate reproduction down to 19 Hz and across the crossover point
- LFE channel output level (0 or +10 dB re. main channels) can be selected for accurate reproduction depending on the source type
- The ability to bypass the subwoofer allows to evaluate the audible impact of the subwoofer
Sophisticated drive unit protection circuitry for safe operation.
When working in critical audio production environments it is essential that monitoring systems remain reliable and functional at all times. One of the main reasons behind Genelec’s excellent success in broadcasting environments is the reliability of our products and a key element behind the reliability is the internal protection circuitry found in all products since 1978.
The protection circuitry prevents driver failures by detecting signal levels, and in case of sudden peaks or constantly too high levels, taking the signal level down automatically. Of course this feature does not affect the sound quality in any way when working within the specifications of the loudspeaker, but only prevents inadequate input signals from breaking the loudspeaker.
Protection circuitry features and benefits:
- Reduces the output level when required, (e.g. when driver voice coil temperature reaches the safe limit) which highly improves the system reliability
- Appropriate protection circuitry design in every loudspeaker and subwoofer enables to maximise system output sound level.
Active crossover operating at low signal levels.
Audio electronic crossovers allow to split the audio signal into separate frequency bands that can be separately routed to individual power amplifiers which then are connected to specific transducers optimized for a particular frequency band.
Active crossovers come in both digital and analogue varieties. Genelec digital active crossovers include additional signal processing, such as driver protection, delay, and equalization.
Genelec analogue active crossover filters contain electronic components that are operated at low signal levels suitable for power amplifier inputs. This is in contrast to passive crossovers that operate at the high signal levels of the power amplifier's outputs, having to handle high currents and in some cases high voltages.
In a typical 2-way system the active crossover needs two power amplifiers — one for the woofer and one for the tweeter.
The active crossover design offers multiple benefits:
- The frequency response becomes independent of any dynamic changes in the driver's electrical characteristics or the drive level.
- There is an increased flexibility and precision to adjust and fine tune each output frequency response for the specific drivers used.
- Each driver has its own signal processing and power amplifier. This isolates each driver from the drive signals handled by the other drivers, reducing inter-modulation distortion and overdriving problems.
- The ability to compensate for sensitivity variations between drivers.
- The possibility to compensate for the frequency and phase response anomalies associated with a driver’s characteristics within the intended pass-band.
- The flat frequency response of a high-quality active loudspeaker is a result of the combined effect of the crossover filter response, power amplifier responses and driver responses in a loudspeaker enclosure.
Using the active approach enables frequency response adjustments and optimization of the full loudspeaker system, placed in various room environments, without expensive external equalizers. The end result is a simpler, more reliable, efficient, consistent and precise active loudspeaker system.

Genelec S360 monitors drive Spain’s first Dolby Atmos Home certified studios
Part of Mediapro’s image and sound post-production company, Telson.Tres60 opened its new facility in May 2019, and decided to upgrade its monitoring capabilities to better serve its clients. “The system upgrades were driven by client demands - for example Movistar asks for everything in Dolby Atmos,” explains sound production co-ordinator, Ana Belén Martín. “We must be able to fit the standards of each of these clients. This means that we have to generate much more material than before because of the different types of broadcast formats – from a mobile phone to a Smart TV.”
The Telson.Tres60 team, alongside Unitecnic – Mediapro’s engineering company which handled the installation – turned to local Genelec partner Audio-Technica Iberia for the 7.1.4 monitoring solution. In both rooms S360A monitors were installed in the LCR positions, with four 1032C monitors as surrounds and the same number of 8340As covering the overhead channels. Low frequency content is handled by a 7382A subwoofer, and with all of the monitors being calibrated and controlled via Genelec’s GLM loudspeaker management software, the monitoring system is able to provide the flexibility required to work to different standards.
“These are the only two Dolby Atmos Home rooms in Spain approved to work at a 79 dB SPL monitoring level,” adds Pelayo Gutiérrez, sound supervisor and head of the fiction sound department of Telson.Tres60. “Ricardo Viñas from Dolby was responsible for adjusting the rooms and equalising them to the three required levels: at 85 dB for cinema, 79 dB for Netflix and 82 dB for Telefónica.”
Alongside the two Dolby Atmos Home rooms, the facility features a 7.1 room, two 5.1 rooms, a foley room and a movie theatre, which also benefit from Genelec monitoring technology. “In terms of technical expectations, Genelec has delivered exactly what we anticipated,” reflects Gutiérrez. “We are very happy – it's a perfect setup. We have real confidence when it comes to making premixes here and moving on to the movie theatre or vice versa - the mixes translate perfectly.”
Genelec and Sound Blanc join forces for unique surround sound performance
Combining an ambient music performance with a multi-channel listening experience, both the performers and the live audience were surrounded by a ring array of Genelec loudspeakers, creating a truly unique listening environment. This type of playback system is tailor-made for ambient music, emphasising the sense of space and the abstract nature of the compositions – and creating an incredibly thought-provoking and stimulating live event.
The planning and creation of the show took place over a two month period, using the demonstration space in Modern Sky to evaluate how the sound elements combined, how they moved, and what type of speaker configuration would be best suited to the ambient material. The creative team included electronic musician Wang Lu, also known as L + R, music producer/mixer Shen Lijia and visual artist Tami-musiXgal, and working alongside our colleagues at Genelec China, a system comprising eight S360 high-SPL smart active monitors and a 7382 subwoofer was used to surround the audience, while a smaller smart active array of four 8330 two-ways, four 8331 coaxial three-ways and a 7360 subwoofer was used to envelop the musician and the VJ. Genelec GLM software was then used to analyse the room and optimise the frequency response, distance delay and playback level of each speaker in the system – thereby delivering the best possible listening experience to both performers and audience alike.
In planning the event, the team were seeking a good combination of manual control, programming and random machine triggering, with the pre-programmed foundation of the 8.1 audio mix being handled by Ableton Live, with Cycling 74’s Max allowing communication with external hardware instruments – and plenty of real-time musical improvisation was included too!
Prior to the event, the demand for tickets was so high that it was decided to stage three separate performances, to allow every listener to position themselves comfortably within the speaker array and experience the finest sound quality. And from our own perspective, the whole process of planning and executing the event gave us a much deeper understanding of the shaping of space, the precise positioning of sound and the design of moving trajectories in music.
There’s no doubt to us at Genelec that as the world’s exposure to immersive audio becomes greater, the future of multi-channel live music performances is increasingly looking brighter. There are a whole new generation of music fans who are seeking more and more ‘experiential’ live performances, and Genelec is excited to play its part in the growth of this exciting medium.
Genelec provides ‘mind-blowing’ sound for Ummet Ozcan
Ozcan has been making music since the age of 14, when his instinctive skill with the flute and keyboard were the first signs of an emerging, prodigious talent. His first single, Chica Good, arrived in 2006 but it was 2011’s Reboot, swiftly followed by 2012’s The Box, that solidified his reputation. In the years since, he has produced not only a string of hit singles but also collaborations with peers including Paul Van Dyk and Tiesto, while continuing to push his own creative limits with the development of soft-synths and soundbanks.
However, most of that work was performed in less-than-ideal listening environments. “The first space that I worked in... I’m not sure I could call it a studio since it was in the attic of my parent’s home,” recalls Ozcan. “I just had two speakers in there – actually just two hi-fi speakers! Then I moved to an apartment and I had a room – so I put some acoustic treatment on the walls, some bass traps, and just two monitors and a sub. I made my music in there for years, but when my friends came to visit I’d tell them to stand in the corner because that’s where they could hear the bass properly! If you took one step to the side then the sound changed completely.”
Ozcan describes his new studio as “everything I’ve dreamed of for the last 15 years – I can’t quite believe that it’s here. This room reflects my energy. It’s an extension of myself and my music. When you close the door, you’re in a different world, it’s amazing.”
The room itself is a blazing celebration of neon, seamlessly shifting between colour schemes to suit the mood of the artist. Sculpted acoustic panels from Artnovion adorn the walls while Morel has even recreated Ozcan’s logo on the ceiling. The Genelec smart active monitoring system which forms the studio’s centrepiece is just as impressive, with two 1234As installed as main monitors, accompanied by a 7382A subwoofer. Adding symmetry, what appears to be a second 7382A is in fact a customised bass trap designed around a Genelec grille. In addition, two of the newly-launched 8351B coaxial point source monitors from The Ones range are installed on Ozcan’s desk for nearfield listening. The DJ describes the sound as “mind blowing”.
Towards the conclusion of the project, Morel and Ozcan shared the process of calibrating the Genelec monitoring system for the room. That work began with Genelec’s GLM calibration software, then was fine-tuned by ear. “We went very deep into the process,” says Morel. Yet ultimately, little tuning was actually required. “You don’t have to do much,” explains Ozcan, “with almost no tweaking it sounds fantastic. You feel it in your chest and it gives you goosebumps because you can hear everything. I can hear things I’ve never heard before!”
For Morel, who has now designed private studios for some of the world’s most celebrated DJ producers, this is one of his proudest achievements. “This ranks as one of the top three studios that I’ve created,” he declares without hesitation. “Certainly for the design, this is number one.”

FAQ
The Classic 8000 Series monitors have an analogue input. The 7200 Series SAM subwoofers have AES/EBU digital outputs only. However, other 7300 Series SAM subwoofers have analogue inputs and outputs and can be used also with analogue monitors.
Which SAM™ Products You Are Going to Mix With the Classic 8000 Series?
Mixing 8000 Series and SAM™ monitors is not recommended
We do not recommend mixing Classic 8000 Series monitors with SAM™ Monitors.
If the analogue input sensitivity of 8000 Series and SAM™ Series monitors are the same, Genelec SAM™ Monitors exhibit a slightly larger latency (< 5 ms) than 8000 Series monitors. Therefore Classic 8000 Series and SAM™ Series monitors should not be mixed in a stereo pair or multichannel setup.
It is alright to mix Classic 8000 Series with SAM™ Subwoofers
However, it is okay to mix the Classic 8000 Series monitors with SAM™ Subwoofers. Any Classic 8000 Series monitors can be used with SAM™ Subwoofers, in any stereo or multichannel setup.
Setting the room response calibration controls
Genelec monitors are calibrated flat in anechoic free field conditions. When the monitor is placed in a room close to walls or other boundaries, the low frequency output of the monitor increases. To achieve a flat low frequency response an adjustment of typically -4 dB on the bass tilt control is used. Genelec also provides a bass roll-off control to compensate for any remaining excessive LF energy around the low cut-off frequency.
Genelec GLM AutoCal can implement a more precise compensation after measuring the acoustic effects produced by the monitor’s installation location.
Differences in room reverberation time and listening distance can lead to changes being required in the treble region so treble tilt is fitted to most of the models in the Genelec range.
In three-way monitors and large main systems there are additional driver controls for the bass level, mid level and treble level which enable very fine adjustment of the frequency response so that the monitors can be placed in many different listening environments, whilst still achieving a consistent and neutral sound reproduction.
The best way to set the room response controls of a Genelec monitor is by taking an acoustical measurement at the listening location, using a measurement system for those products that offer local controls (DIP switches) on the monitor or subwoofer, or by using GLM AutoCal for the SAM™ (Smart Active Monitoring) products.
