Logically intelligent.The Linea Focus family.The innovative, finely tuned Linea Focus family differentiates itselffrom other products because of its column length. This is due to thenumber of integrated loudspeakers, amplifiers and DSP channels,which enable each individual speaker to be electronically controlled.The flagship LFI-450, for example, contains 32 integrated loudspeakers,32 amplifiers and 32 DSP channels. The vertical soundinclination angle can be adjusted between -40°/+40° and the verticalbeam width between 0° to 90°. Using Fohhn’s intuitive software,adjustments are made in unbelievably fine and precise 0.1° steps.An outstanding feature of the Linea Focus series is Fohhn’s “Two BeamTechnology”. This allows the speakers to generate two separate beamsin their vertical dispersion range, providing simultaneous and focussedcoverage of different audience areas, such as stalls and gallery.A further unique feature is Fohhn’s new “Side Lobe Free Technology”,a special algorithm developed in house to suppress the unwanted sidelobes that will inevitably occur in the beam. This results in a moredirectional sound and significantly improved speech intelligibility.The different lengths of the Linea Focus models determine theiracoustic efficiency. The longer the line array, the longer its reach andalso its effectiveness in the control of low frequencies. Multiple LineaFocus systems can be networked together to enable monitoring andcontrol from a central location.10 | Fohhn

Mobile Applications.Press conferences, worship sound, industry events, broadcast and TV shows,galas, exhibition stands, concert tours, theatre productions and more.With an emphasis on design, architecture and sound quality,Linea Focus systems are ideal for live use where it’s important forloudspeakers to maintain a discreet, professional profile, ratherthan dominating the scene. Quick set-up is another importantfactor, along with the ability to function flawlessly, even in themost demanding acoustic conditions.Larger modular line array systems often require flying points andexpensive coupling devices, but Linea Focus simply requires a loudspeakertripod, or a mounting point on a traverse. Due to its arraylength, Linea Focus provides excellent reach and coverage. Thespeakers’ slim, unobtrusive design allows an unrestricted view of thestage and won’t interfere with any camera work. An ability to controlthe sound direction also avoids potential conflict with any complexmicrophone set-ups.Linea Focus systems are light and compact,convenient for both transportation and storage.* Low weight (LF-120: 8 kg; LF-220: 15 kg)* Elegant design (width: only 13 cm)* Connection plates on the underside of thebox for quick and easy access* Networkable – up to 256 systems12 | Fohhn

Industry events often take place in venues withdifficult acoustic conditions, where the PA systemis temporarily installed. Even so, quick set-up,decent appearance, and good sound quality(despite any complex microphone set-ups) are allexpected. In these situations Linea Focus copesmagnificently, allowing you to control the soundprofessionally and unobtrusively from a centrallocation, without requiring any additionalspeaker cabling.100%SOUNDFohhn | 13

Fixed Installations.Airports, churches, railway stations, conference centres, theatres,TV studios, university lecture rooms, exhibition halls, Museums Etc.The Linea Focus LFI series has been specially developed for venues thatdemand both powerful sound reproduction and visual integration.The new 4.5 m length is a recent innovation – rarely seen on the market.Its numerous speakers generate superb coverage over impressive distances.In reverberant acoustic conditions, excellent results can beachieved by focussing the speaker sound to avoid “exciting” the roomacoustic, guaranteeing superb speech intelligibility. The electronicallysteerable capabilities of the new systems allow them either be mountedflat on the wall, or installed directly in the wall.An international study by Prof. Dr.-Ing. Jürgen W. Meyer (Physikalisch-Technische Bundesanstalt, Germany) has revealed that historicalchurches often have long reverberation times in the particularfrequency range relevant to speech. Strong reverb considerablyreduces speech intelligibility. Here however, Linea Focus proves a realproblem solver. By targeting the sound directly towards the audience,speech intelligibility is significantly improved.System integration in accordance with EN 60849(emergency and fire evacuation)* Two independent line inputs with symmetrical transformers* Fault message contact* 12-64 V emergency power operation* Monitoring of all important device parameters* Intelligent evaluation14 | Fohhn

Linea Focus – An overview ofthe main operating principle.Operating a Linea Focus system is easy, even though there are highly complexprocesses integrated into both the technology and the software.The diagram on page 19 gives more experienced readers an overviewof the functionality. An input signal initially passes through the inputsection. This has a priority logic that is activated if an evacuationannouncement is necessary for example, ensuring maximum safety inany kind of emergency. The input signal also passes though a digitalsignal processor, which offers a range of opportunities for real-timeprocessing. This is done easily and intuitively using Fohhn Audio Softsoftware. The “Speaker Setting and Protection DSP” section includesall the necessary acoustic protection mechanisms, such as a finelytuned multiband limiter. Equalizer settings, for the array correctionfor example, can also be stored.The system is continually optimized to deliver excellent acousticresults and maximum operating reliability, even under difficultconditions. At the heart of the Linea Focus system is the “BeamControl DSP” display, which includes all the algorithms for calculatingthe beam characteristics. Any parameter changes made by the user inthe software are then sent to the Beam Control DSP, which calculatesthe data and relays the appropriate information to each separatespeaker.Each chassis is controlled via an individually calculated signal from itsown Class D power amplifier. Constant monitoring of the state of eachindividual output signal and component, such as temperature, currentand load, means that the present operating status is always displayedand can be read by the user.18 | Fohhn

Linea Focus SoftwareSimulation.At the Heart of Fohhn Audio Soft V3.100%IntuitivEAt the heart of Fohhn Audio Soft V3 is the Linea Focus Simulation. Theunique integration of control and simulation allows the immediatetransfer of parameter settings to the connected devices. All parameterchanges made in the simulation window are transferred to the devicesin real time. Changes to the sound inclination angle or beam width areinstantly audible. The vertical sound inclination angle can be adjustedbetween +40°/-40° and the vertical beam width between 0° to 90°.The simulation of the line array’s sound dispersion characteristics lieswithin a frequency range of 50 Hz – 20 kHz. The spatial distributionof the sound pressure level is displayed in graded colours. Thefrequency response at any given position, and the sound pressure levelfor any area of the audience, can be displayed on a graph. Optimizingthe sound dispersion characteristics can always be done in real time.Using a laptop with WLAN lets the user move around, quickly assessand optimize the sound in each part of the room, before comparing itagain with the simulation.Fohhn | 23

Fohhn’s Top 5: A more detailed look at the main advantages1. Superb sound qualityin challenging acousticenvironments.Linea Focus takes sound reproduction of both speech and music to thenext level. The speakers’ sound dispersion characteristics can beadjusted to suit the room conditions, avoiding unwanted reflectionsand providing even coverage of all audience areas. Because of this,it’s possible to achieve superb speech intelligibility and a clearcohesive image, even in the most demanding acoustic conditions.In comparison: Conventional PA systems have more permanentlydefined sound dispersion characteristics. These are usually either toowide, or they lack cohesion and cannot be specifically adjusted to suitparticular room conditions. It’s also unnecessary for sound to befocussed in places where there is no audience. This sound oftenreflects off areas like the ceiling, causing a delay on its return. To thelistener, this kind of reflection can make the sound appear “washy”or “roomy”, with a noticeable deterioration in speech intelligibility.In this respect, the Linea Focus series is revolutionary: Specificallytargeting the sound means that unwanted room reflections can beavoided.24 | Fohhn

Without Side Lobe Free TechnologyOne A single Beam beamWith Side Lobe Free TechnologySIDE LOBE FREETechnologyThis specially developed algorithm can suppress unwanted sidelobes. Superb speech intelligibility is achieved due to the reducedroom reflections.Two seperate beamsTWO BEAMTECHNOLOGYThis innovative Fohhn development enables two separate beamsto be generated in the vertical dispersion range, allowingspecific audience areas such as stalls and gallery to be targetedby the same speakerUsing the two unique control tools – “Side Lobe Free Technology”and “Two Beam Technology” – developed by Fohhn engineers,different audience areas can be simultaneously targeted, avoidingunwanted room reflections.Fohhn | 25

Fohhn’s Top 52. Real-time sound control.Perfect control equals perfect results. Fohhn’s user-friendly softwareenables real-time control of the speakers’ sound dispersioncharacteristics. This allows sound to be focussed quickly andaccurately on each particular audience area, giving outstandingresults with both fixed installations and live performance systems.Control via computer keyboard or mouseWith most sound projects, time is often a decisive factor in determiningtheir eventual success or failure. Because the loudspeakersystem is invariably installed at the end of a construction project,or live set-up, time may be limited to quick and rudimentaryadjustments and sound checks. Being able to control the sounddispersion in real-time makes the set-up considerably easier.26 | Fohhn

Fohhn’s Top 53. Even sound distribution.With Linea Focus, even sound distribution is guaranteed throughoutthe venue, from warm, pleasant sound at the front, to clarity anddetailed intelligibility right at the back. What‘s more, significantlyfewer speakers are required to achieve perfect room coverage. As atrue line array system, Linea Focus produces its sound in the form ofa cylindrical wave. Unlike conventional systems, the sound pressurelevel within the cylindrical wave only decreases by 3 dB, insteadof 6 dB, as the distance doubles. This groundbreaking feature,combined with the ability to electronically control the speakers’sound dispersion, has set new standards in sound quality.For planning ingenieurs we offer a plugin(DLL) of Fohhn Audio Soft for EASE acousticsimulation program.28 | Fohhn

Fohhn’s Top 54.Outstanding reproductionof speech and music.Linea Focus also establishes a new benchmark for the reproduction ofspeech and music. The high-powered speakers’ exclusive developmentand innovative digital technology produces a dynamic, natural soundquality. Speech, AV productions and live music are all superblyreproduced with Linea Focus systems. Each separate loudspeaker isindividually equipped with one of the latest generation CLASS D DSPamplifiers, producing 100 W path power per channel. A Linea FocusLFI-450 system, for example, has 3200 W of available amplifier power.If higher bass sound pressure levels are called for, the Linea Focussystem can easily be combined with a Fohhn active or passivesubwoofer. To target sound more effectively in the low frequencyrange, it’s also possible to create a bass array by combining severalsubwoofers and their related DSP technology.The Linea Focus systems’ extraordinary electronic control capabilitiesalso allow the speakers to be used in combination with Fohhn subwoofersystems. Electronically steering each separate DSP-controlledsubwoofer enables more precise control of its sound dispersioncharacteristics. This in turn gives a more even reproduction of lowfrequencies, which significantly improves the overall sound image.For further information, please contact our planning engineers oninfo@fohhn.com.30 | Fohhn

The Fohhn ® Sound Lab.Fohhn`s new Sound Lab offers a great opportunity to carry out fundamentalaudio research and to develop leading-edge technology.In the Nürtingen factory premises, Fohhn’s new Sound Lab offers agreat opportunity to carry out fundamental audio research and todevelop, measure and test leading-edge technology. Engineers from arange of different backgrounds work closely together to push theboundaries of audio technology.The Fohhn Sound Lab also provides customers with an excellent venuefor thorough testing of the capabilities of Fohhn audio systems. Newpaths to tread, better solutions to develop and the highest technicallevels to aim for – that’s the mantra of Fohhn’s R&D division. The samegoal-driven, scientific approach is applied in all areas of developmentfrom electronics and software to acoustics and mechanics. Creativeconcepts for new loudspeakers are quickly translated into theory,based on extensive calculations. Numerous computer simulations andprototyping phases follow, in which each parameter – frequencyresponse, dispersion characteristics, dynamics, distortion, largesignal response – is recorded, adjusted and optimized. The next stageinvolves specifically optimizing the amplifier electronics, digital signalprocessors (DSP) and remote control/networking technology for theloudspeaker. Each development phase, from the mechanics through tothe software, is carried out at Fohhn.At the end of the development process, all newly created productsundergo lengthy and rigorous practical tests; both at Fohhn and inlive situations. “Practical testing” at Fohhn includes everyoneinvolved in the development process. Fohhn engineers, marketing anddistribution personnel, who all have experience as live soundengineers, musicians or DJs. This way, each new product can also becarefully scrutinized from a user’s viewpoint. The result is a perfectloudspeaker system that combines optimum sound characteristicswith total operating reliability. A system that is simple and safe touse, ready to give maximum performance and real listening pleasure.Optimum Research and Test ConditionsWith a floor area of 24 meters x 14 meters and a height of 6.5 meters,the Fohhn Sound Lab is one of Germany’s largest and best equipped36 | Fohhn

Customers attend a demo in the Fohhn Sound Labaudio measurement facilities. It enables developers to measure eachloudspeaker parameter very precisely and to assess the relevanceof the captured data while listening. Only under such specialistconditions can a loudspeaker’s performance be optimized to thehighest level. A combination of room size and highly developed FFTmeasuring systems enable reflection free measurements to be obtaineddown to 100 Hz – something that is usually difficult to achieve.The amount of wall clearance means that dampening the room toachieve an “anechoic chamber” effect has not been necessary.Instead, at great expense, absorbers and diffusers have been used toconvert the former warehouse into a dedicated listening space withsuperb acoustics. With a natural room reverb of approx 0.4 seconds,Fohhn’s new Sound Lab offers top testing conditions.Fohhn’s 2-Axis Measurement Robot enables continuous 360° measurementFohhn’s 2-Axis Measurement RobotAnother technical highlight of the Fohhn Sound Lab! This impressivedevice gives us the opportunity to measure very large loudspeakersystems. The robot has been specifically developed by Fohhn for thispurpose, and is able to pan through both speaker axes at 360°,with a positioning accuracy of 0.3°. The device enables the speaker’sdirectional characteristics to be assessed and optimized during eachdevelopment stage – from the speaker chassis to the finishedprototype. The polar pattern data obtained by running Fohhnloudspeakers through room simulation programs such as EASE orULYSSES, can also be analyzed and optimized. This is achievedby making several hundred individual measurements, with the robotpositioning itself at a different angle each time. A series of measurementsfor a single system can take 12 hours or more to complete.Fohhn | 37
