    En studiomonitor ska vara fullt transparent för det ljudmaterial som återges. Den ska inte lägga till, ta bort eller maskera någonting i materialet, detta med minimal påverkan från omgivningen. Det vi hör är summan av våra örons uppfattningsförmåga, högtalarens prestanda och rummets akustik.

    Att välja rätt högtalare
    Genelecs rekommendationer för vilken högtalare du ska välja baseras på avstånd till högtalaren samt önskad ljudtrycksnivå. Till varje högtalare finns även en matchande subwoofer. På Genelecs hemsida finns verktyg som gör det enklare att välja rätt högtalare. Läs mer här.

    Här kommer några tips på hur du hittar rätt lyssningsavstånd och tar reda på den optimala lyssningspositionen:

    Specificera din lyssningsposition
    Dela in rummet i tre lika stora delar: en främre del, mitten och en bakre del. För musikproduktion placerar du dina studiomonitorer i den främre delen. Vinkeln mellan den vänstra och den högra högtalaren ska vara 60 grader. Båda högtalarna ska vara riktade mot lyssningspositionen.

    Rumsresonansen som uppstår mellan rummets ytor kallas stående vågor eller rumsnoder. Det maximala ljudtryck som uppstår av rumsresonansen sker mot plana ytor, därför bör du placera lyssningspositionen minst en meter från någon av väggarna för att undvika att hamna där rumsresonansen är som starkast.

    Mät upp var i rummet mittlinjen går och placera högtalarna symmetriskt på var sin sida om mittlinjen.

    För en typisk setup med två studiomonitorer rekommenderar vi att högtalaren placeras så att dess akustiska axel ligger i höjd med lyssnarens öron, vanligen mellan 1,2 och 1,4 meter över golvet. För att minimera reflektioner från golvet kan högtalaren vid behov placeras högre med en lätt vinkel nedåt.

    För återgivning av ljud i stereo eller flera kanaler rekommenderas dock inte en placering där högtalaren måste lutas nedåt mer än 15 grader. Högtalarna ska alltid vara riktade mot lyssningspositionen. Ju högre upp från golvet högtalarna sitter desto lägre är risken för frekvensgångsstörningar orsakade av reflektion. Dock ska man försöka undvika att placera högtalarna högre än halva rummets höjd eftersom lägre frekvenser även reflekteras i taket.

    Förslag på hur monitorer kan placeras i två olika typer av rum.

    Placering av högtalare och lyssningsposition i rummet
    Ljud reflekteras från väggar, tak och golv. Ljudnivån för lyssnaren ökar när det reflekterade ljudet är i fas med det direkta ljudet. Om rummets ytor inte utformats så att de diffrakterar ljudet kommer det mesta av ljudet att lämna väggen med samma vinkel som det träffade den. Undvik därför att placera högtalarna så att reflektionerna från den närmaste sidoväggen, taket eller golvet träffar lyssningspositionen.

    Utsläckning mot den bakre väggen – högtalarplacering
    För att undvika att ljud dämpas eller försvinner på grund av att det reflekteras mot väggen bakom högtalaren bör du följa de här placeringsråden:

    Den här typen av reflektion uppstår bara vid relativt låga basfrekvenser. För att högtalarens basfrekvensåtergivning inte ska uppfattas som för låg är det viktigt att undvika det här fenomenet. Det gör du genom att placera högtalaren så att det är maximalt 60 centimeter från väggen till högtalarens framsida. Det säkerställer att de låga frekvenserna inte dämpas. Det minsta mellanrummet som krävs för att högtalarens bakre basreflexport ska fungera optimalt är fem centimeter.

      Iisalmi, Finland, March 2020... Genelec is proud to unveil the 1235A Smart Active Monitor, which fuses the sound and heritage of the iconic 1035 main monitor with high performance 96 kHz processing and the ability to adapt to any space through its tight integration with Genelec’s GLM calibration software. The 1235A is therefore the perfect main monitor for large music, film and post production studios that demand high SPL, and neutral, stable imaging that can be perfectly optimised for the room’s unique acoustic environment.
      Launched in 1989, the original 1035 became an industry standard throughout the world, fulfilling the need for a wall-mountable full-range monitor that could deliver true reference performance at high SPLs and over long listening distances. Legendary studio designer Sam Toyoshima was an early evangelist for the 1035, and as a result it was quickly adopted by many of the world’s finest studios, including Metropolis and Olympic in London and JVC and West Side in Japan.
      The new 1235A shares all the finest characteristics of its forerunner. Outstanding frequency response both on and off-axis, coupled with superb directivity, results in a very wide and stable sweet spot that can be trusted by multiple listeners within a room. With a short term SPL of 130 dB and low frequency extension down to 29 Hz, the 1235A also delivers staggering power, but its transparent uncoloured performance ensures that the listener can still make accurate, reliable mix decisions even after long sessions.

      The 350 litre enclosure of the 1235A matches exactly the dimensions of the 1035, and features dual high performance 15” drivers, dual 5” midrange drivers and a low distortion 1” throat compression driver. The midrange and tweeter drivers work in conjunction with proven DCW waveguide technology to produce the outstanding directivity and smooth, consistent imaging for which the Genelec brand has become renowned. The 1235A’s remote-mountable RAM XL electronics module contains power amplification, crossovers and processing, with Class D amplification delivering 2000 W, 800 W and 250 W for the LF, MF and HF drivers respectively. Input connectivity is provided via both analogue and AES/EBU digital formats – along with an AES/EBU digital output – and the updated design of the 1235 also delivers a flatter on-axis frequency response and improved noise performance than was possible with the original 1035.
      Through its integration with GLM software, the 1235A can be configured, controlled and calibrated for any type of acoustic environment, allowing the user to tailor the frequency response, level, distance delay and more, to provide a truly optimised listening experience – and mixes that translate perfectly to other rooms and systems. GLM allows users of any type of Genelec Smart Active Monitors to easily and swiftly create systems to suit all types of stereo, multiple stereo, multi-channel or 3D immersive audio formats.
      Happily, the technology of the new 1235A is also available as a retrofittable on-site upgrade for existing owners of 1035A and B monitors. The upgrade, which includes installation of the new RAM-XL module, brand new drivers and a complete system calibration, can be completed with no structural changes and little downtime, enabling 1035 users to benefit from improved performance, greater flexibility – and many more years of reliable service from their monitors.
      Genelec Managing Director Siamak Naghian comments:
      “While control room sizes are generally shrinking, there is still a clear demand from the worlds of music, film and post for main monitors that can deliver pristine truthful performance at very high SPLs. Sitting happily between our 1234 and 1236 main monitors, we are sure that the technology of the 1235A will be warmly embraced by those building new rooms, and existing owners of vintage 1035s that now want to take advantage of all the power and flexibility that our Smart Active Monitors offer. The first pair of 1235As is already destined for Metropolis Studios in London, and we’re excited about the potential for this reborn Genelec classic!”
      The 1235A is available now. For more details, please visit www.genelec.com and for more information about 1035 upgrade options please contact your local Genelec distributor.

      Baton Rouge, Louisiana—February 2020… Once upon a time, there was a family of Eris who lived at PreSonus down on the Louisiana bayou. There was a great big Eris named E8 XT; a middle-sized Eris named E7 XT, who just recently joined the family; and the cher petite  E5 XT. The Eris family also had two sets of nearly identical twins: Eris E4.5 and E4.5 BT and Eris E3.5 and E3.5 BT. (The Eris family included two cousins, E44 and E66, but that’s a story for another night.) Over the years, the Eris family became very popular on the bayou and far beyond, and for good reasons.
      Eris E8 XT is very powerful indeed, and his 8-inch woven composite woofer and large size results in a deep rich voice that reaches all the way down to 35 Hz. His voice is best appreciated in a moderately large studio space for those that appreciate a big bass sound. Eris E5 XT, with his 5-inch woofer, sounds great in smaller spaces, such as bedroom studios, but his voice doesn’t reach as low as the mighty E8 XT, and he might be too small to fill large studio spaces.
      The newest member of the family, Eris E7 XT, is just right for moderate-size and some mid-large studio spaces. With her 7-inch woofer and 1.25-inch silk dome tweeter, E7 XT’s voice is significantly more powerful and richer than that of the smaller Eris family members, though not quite as deep as the E8 XT’s. Featuring the same 140W of Class AB biamped power as the E8 XT, the E7 XT can deliver tight, focused bass down to 42 Hz despite her compact form factor. And just like the E8 XT and E5 XT, Eris E7 XT is equipped with PreSonus’ custom Elliptically Boundary Modeled waveguide, which enables her to be clearly and accurately heard across a wide 100 degree “sweet spot” with a focused 60˚ in the vertical to minimize desk reflections and maximize performance.
      Whether singing at the top in her range or hitting the low notes, Eris E7 XT always delivers the truth. If you need to bring an instrument up or down in a mix or your EQ’ing is off, she’ll let you know. Like the E8 XT and E5 XT, she is extremely flexible, offering acoustic tuning controls that enable you to adapt her voice to the room’s response and to placement close to walls or corners, and she accepts input via XLR, TRS, and RCA connections.
      Eris E7 XT is available now at your favorite PreSonus dealer at an expected U.S. street price of $229.95 each.

      Iisalmi, Finland –January2020.....Genelec – the global leader in professional audio monitoring –is proud to be showcasing two Smart IP loudspeaker models at the forthcoming ISE show in Amsterdam.The 4420 and 4430 loudspeakers combine both exceptional sound quality with single cable convenience, and their onboard Smart IP technology provides scalable power, audio and loudspeaker configuration, supervision and calibration features via a standard CATcable. Smart IP therefore offers system designers, integrators and installers an easy, powerful and cost-effective solution for guaranteeing enjoyable, high-quality audio across entire installations.
      Having been unveiled before aselect audience of specially invited Nordic integrators in Helsinki in December, the 4430 will be making its ISE debut alongside its new and even more compact 4420 sibling –with yet more Smart IP models expected to be added to the familyin the future.


      Producing the clarity and intelligibility for which Genelec has become a benchmark, the 4420 and4430 are compatible with both Dante and open IP standards including AES67and ST2110-30, and derive power viaPoE and PoE+ Power-over-Ethernet formats. Both models feature a single rear panel CATconnector which alsoallows access to Genelec’s Smart IP Manager -a sophisticated software tool that allows installers to configure an almost unlimited number of rooms, zones, loudspeakers and audio channels, and includes device discovery, a versatile room equalisation tool set, system organisation and status monitoring. This enables installers to deploy Smart IP loudspeakers even on highly complex, acoustically challenging projects.
      While Smart IP Manager isdesigned specifically for installers to use during set-up and configuration,the 4420 and 4430 can beintegrated easily into house automation systems using a public API command set–allowing the end user instant access to volume, poweron/off, loudspeaker activity and a selection of pre-programmed audio settings.Smart IP supports uncompressed low-latency audio streaming directly into each loudspeaker, with loudspeaker synchronisation to sub-microsecond level for solid acoustic imaging. Streams can be managed by both Dante Controller and Dante Domain Manager software, as well as legacy balanced line analogue audio. This flexible connectivity allows both IP control of an analogue source, or use of analogue audio as a failsafe back-up.
      In terms of technical specification, the 4420 stands just 226 mm tall yet offers a frequency response of 55Hz –39 kHz(-6 dB) via a 4inch woofer and 3/4 inch metal dome tweeter, producing a max SPL of 100 dB via onboard 50W Class D amplifiers for eachdriver. In comparison,the 4430 measures 285 mm in height, delivers 45 Hz to 39 kHz (-6 dB) via a 5 inch woofer and 3/4 inch tweeter, and produces a max SPL of 104 dB via its onboard 50 W Class D stages. 
      Manufactured sustainably to offerlow power consumption, total reliability and long life, the 4420 and 4430 enclosuresare produced from recycled aluminium, are available in black, white or 120 custom RAL colours, and arecompatible with Genelec’s extensive range of mounting accessories to allow both models to be floor, ceiling, wall or truss mounted.
      Looking ahead to the forthcoming ISE show, Genelec Managing Director Siamak Naghian commented:
      “With the 4430 already being utilised on prestigious Nordic installations -including Helsinki’s Finnish Music Hall of Fame, Moesgaard Museum in Aarhus and the new G Livelab music venue in Tampere, we’re confident that the new 4420 will also be embraced by installerslooking for an even more compact Smart IP loudspeaker solution. The overwhelmingly positive feedback that we’ve received from the early adopters of Smart IP makes us extremely excited about ISE -and the potential of our AV Installation business in the future.”
      Genelec will be showcasing the 4420 and 4430 on Stand 3-B115 of the ISE Show, which takes place in Amsterdam between 11th and 14th February.

      Ibiza, Spain, February 2020... Superstar DJ, Godfather of EDM, and “the man who almost single-handedly resurrected dance music in America”, it’s hard to overstate David Guetta’s huge influence on the modern music scene. Having DJ’d in Ibiza for over 20 years, Guetta’s personal studio on the island has recently been upgraded with a pair of Genelec 7380A subwoofers, which join his existing Genelec 1234A three-way main monitors to create a smart monitoring system that Guetta describes as “my perfect setup.”
      The new solution came about after Guetta identified a problem with the mixes that he was creating with his old system. “In the previous system that I had, the subs were so loud that they were not really realistic,” he explains. “If I would mix with those subs, sometimes I would end up with a record that didn’t have enough bass when played on other systems -because the bass in my room was so huge.

      ”With the 7380As installed, Guetta’s mixes now translate beautifully from his studio straight to the dancefloors of Ibiza, and the subwoofers have helped improve the overall sound in his room. “By installing the subwoofers, we were able to reposition David’s main monitors to avoid early reflections. Finding the best place for the subwoofers also meant that we had a great frequency response curve all the way from low to high frequencies,” notes Genelec’s Pasi Pönkkä, who travelled to Guetta’s studio to calibrate the system using Genelec’s GLM software. Using GLM, Pönkkä was able to analyse the acoustic environment of Guetta’s studio and then optimise each Genelec monitor and subwoofer accordingly -thereby reducing any negative influences of the room on the sound. 
      Pönkkä explains that “Each 7380A subwoofer is paired with a single 1234A monitor, so the low frequencies can be better localised. Also, the locations were chosen so thatthe subwoofer sums aren’t cancelling each other out. The overall result was that we were able to provide David with more bass extension, but with a much smoother and flatter response.”
      A further benefit that Guetta is enjoying is that he can now work formuch longer periods without the listening fatigue that he used to experience. “When producing, I’m not really playing too loud, and the Genelec 1234As -even though they are huge -still sound very precise even when they aren’t loud,” he explains. “What I like about the 7380As is that I can work at a low volume so that I’m not too tired after a few hours, and it’s still very precise. But, if I want to blast it loud, it’s powerful enough to feel like it’s in a club".
      Reflecting on his newly upgraded monitoring system, Guetta is certain he made the correct decision. “It gives the feeling of how it’s going to sound in the club, but it’s also realistic,” he states. "This is my reference, and this is my perfect setup.”
