Switzerland - Winkler Livecom of Switzerland has added 200 Elation Professional KL Fresnel series luminaires to its inventory.
Winkler, based in Wohlen, near Zürich, is one of the largest full service companies in Switzerland, handling virtually all aspects of exhibition, corporate and public events from initial idea to execution. Since its founding in 1996, Winkler has often employed Elation lighting in its broad portfolio of projects, but the KL Fresnel acquisition marks the company’s first purchase of Elation gear.
“We continue to replace our bulb-based static lights with LED versions and invited several distributors to a shoot out here at our facility,” recounts Frank Burghardt, head of sourcing at Winkler Livecom. “Elation’s Swiss distributor Cast came with the KL Fresnel 4 and Kl Fresnel 6 and in the end it was the price vs performance ratio of the KL series that was the best.”
The KL Fresnel Series is a line of warm-white or cold-white LED Fresnel lights available in 50W, 150W and 350W models. Winkler acquired the 50W KL Fresnel 4 CW (50) and 150W KL Fresnel 6 CW (150), cold-white LED Fresnel lights with a 5,600K Cool White LED engine. Both luminaires include manual zoom, manual and DMX controlled dimming, and silent operation mode. Barn doors and gel frame holder are also included.
“We decided to invest in the cold-white version and then we can add full CTO or half CTO filters when we need a warmer look. It was a smart solution and gives us the flexibility to cover a wider color temperature range,” states Burghardt,
USA - L-Acoustics has announced the new Kara II modular line source. The addition of Panflex gives Kara four-in-one directivity: one box handily covers any audience geometry. Kara II morphs to fit any design, offering consistent coverage and SPL distribution with precise focus in four different directivity patterns: 70° or 110° symmetrical and 90° asymmetrical, steering to either the left or right, says the company.
In a nod to the wide audience of Kara owners around the globe, L-Acoustics will make available a kit to upgrade existing Kara with Panflex.
Florent Bernard, executive director of application design at L-Acoustics explains, “Kara has been a perpetual best-seller for a reason. Its lightweight, diminutive form factor and strong, consistent SPL make it the perfect tool for a plethora of events or permanent installs. When we introduced Panflex to the industry, our clients told us this was the only thing missing from Kara. We listened, and the new Kara II brings our medium-format line array into a new era of added directivity and improved polar stability.
“Kara II is a powerhouse enclosure, meeting the needs of any audience geometry and morphing to fit any design, offering consistent coverage and SPL distribution with laser focus. As with all L-Acoustics K Series line arrays, Kara benefits from decades of research and development into quick and safe rigging, making it the reference in the market for rapid and optimized deployment.”
USA - DiGiCo has reveaedl the latest in Quantum console range. Like Quantum7 and Quantum5, Quantum338 represents “a dramatic leap forward in power and connectivity”. It includes new design features and enhancements that offer “ultimate flexibility, all with the same speed of operation that Quantum users have come to rely on, in a smaller format console”.
“With Quantum338, we have ensured that we are providing a next generation console that works in synergy with our Quantum Engine,” says Michael Aitchison, DiGiCo’s senior electronics engineer. “We focused our R&D team on user experience, learning from the last 20 years, with our continuing main objective of merging new with familiar.”
Quantum338 is based on seventh generation FPGAs and includes 128 input channels with 64 busses and a 24 x 24 matrix, all with full channel processing. There is a new look and feel dark mode application and three 17 inch 1000 nit, high brightness, multitouch screens, allowing both the meter bridge and soft quick select buttons to be displayed on each screen. There are also 70 individual TFT channel displays and the floating Quantum chassis features 38 x 100mm touch sensitive faders laid out in three blocks of 12 fader banks, plus two dedicated user-assignable faders, each complete with high resolution metering.
A new level of local audio connectivity and performance comes via the ‘Ultimate Stadius’ 32 bit ADC and DAC conversion, which are built in to Quantum338 as standard, alongside six single or three redundant MADI connections, dual DMI sl
UK - Leeds City College is the city’s largest educational establishment, offering a wide variety of courses to more than 25,000 students. The college recently expanded its facilities with the new £60m Quarry Hill Campus, home to the School of Creative Arts, featuring an Allen & Heath dLive digital mixing system.
Following a recommendation and demonstration by the audio sales division of A.C. Entertainment Technologies (AC-ET), the college opted for a dLive C3500 control surface and CDM48 MixRack, fitted with a Dante 64x64 networking card, for the campus’ soon to open theatre.
For use by both Theatre Design & Production and Music Production students, the dLive system will also be employed for public performances by theatre companies and community groups during holiday periods and outside of college hours. As such, the new system needed to meet a variety of criteria as the College’s chief theatre technician and teacher, Paul Graham-Bell explains.
“We looked at several models from different manufacturers when trying to find a mixing solution to meet the demands of the theatre,” he says. “The Theatre Design and Production students are taught sound design for dance and musical theatre, while Music Production courses cover both live sound and recording, so flexibility was very important. The control surface also needed to be simple enough to learn the basics of mixing, but also sufficiently powerful for students to explore advanced features and techniques. We also wanted to invest in something that was popular within the industry, to
USA - DMI-KLANGDiGiCo has announced the new DMI-KLANG, an immersive in-ear mixing expansion that can be mounted directly into DiGiCo consoles, equipped with DMI slots.
KLANG’s immersive in-ear mixing systems make spatial and transparent in-ear monitoring possible. With lower listening levels - on average up to 6dB less - it eliminates the feeling of isolation associated with a normal in-ear stereo mix and offers less fatigue. Its applications range from personal mixing for touring monitor engineers to spatial mixing for recording studio sessions.
The DMI-KLANG follows in the footsteps of the KLANG:fabrik. "This is the first hardware product since KLANG and DiGiCo joined forces,” says DiGiCo’s general manager, Austin Freshwater “We took KLANG:fabrik’s immersive in-ear mixing core and rebuilt it with today’s latest FPGA technology. With one device, we can now deliver immersive mixes of 64 inputs for 16 musicians. This is the highest input count of any KLANG product to date. And the best thing is, we were able to bring the processing latency down to a quarter of a millisecond.”
The DMI-KLANG connects directly to DiGiCo consoles’ internal audio stream without any additional hardware I/O or overhead. This makes it possible to route any audio channel from the console to the DMI-KLANG and return the immersive mix to the Aux merge input. Via the DiGiCo KLANG console link, monitor engineers can stay in their usual mixing workflow, use snapshots, faders and knobs, but with all the benefits of immersive in-ear mixing. This makes it the perfe

Europe - Award-winning independent French theme park, Puy du Fou, unveiled its first venture in Toledo, Spain with an epic night-time immersive spectacular El Sueño de Toledo (The Dream of Toledo), creatively directed by Nicolas de Villiers and the team from Puy du Fou with lighting designed by Koert Vermeulen from Belgian creative visual practice, ACTLD.
At the heart of Koert’s lighting spec are 74 x Robe BMFL WashBeam and 20 x MegaPointe moving lights.
El Sueño de Toledo takes spectators on a hi-octane condensed one-hour journey through history – from the Reign of Ricaredo in the 6th century to the arrival of the railways – touching on the battle of Navas de Tolosa and the discovery of America along the way! The 1500 years of history is represented by 185 actors and a plethora of special effects.
Koert and Nicolas have worked together on several previous Puy du Fou live shows and projects in France. The show is staged outdoors on a performance space approximately 125m wide by 100m deep, rising up towards the back. The set includes several permanent buildings and structures and a large lake, with the action taking place both on, in front of, and behind the water.
Nicolas briefed Koert on the historical narrative and Koert produced a lighting concept for the show which is played out by the large cast to a special soundtrack composed by Nathan Stornetta.
“The show’s essence was similar to some of those we have created in the French park, so some of the base principles and style needed to reflect a continu
USA - Audio-Technica has announced the expansion of its 3000 Series frequency-agile true diversity UHF wireless systems with the addition of a network port. The ATW-R3210N receiver, which receives its NAMM debut this year, now allows network control and monitoring along with the same easy setup, versatile operation and rock-solid, richly detailed high-fidelity sound as standard 3000 Series components.

USA In Anaheim this week, Yamaha is launching new white models of its flagship DZR/CZR series and DXS XLF/CXS XLF loudspeakers / subwoofers.
All DZR/CZR and DXS XLF/CXS XLF models will be available in the new white finish, providing more options for a greater variety of uses, such as hotel banquets, houses of worship and auditoriums, where a high quality audio system needs to blend into the design of the space.
The DZR range comprises eight full-range models and four DXS XLF subwoofers, including ‘D’ versions that feature onboard Dante IN/OUT capability. Featuring best-in-class SPL performance, sophisticated 96kHz DSP processing and unrivalled low-frequency sound reproduction, DZR loudspeakers deliver professional quality sound with greater power than their compact, lightweight design might suggest. The DXS XLF subwoofers can reach an extended low frequency of 30Hz, the lowest of any DXS subwoofer yet.
The passive CZR series features three full-range models, with two CXS XLF subwoofers. They share the same cabinet and speaker components as the DZR/DXS XLF models, delivering high power-handling and focused, professional sound.
Optional accessories for the new models include a white U bracket that is easy to install in both vertical and horizontal configuration. The existing SPCVR series speaker covers for all models (available in black only) and wheel kit for DXS XLF / CXS XLF subwoofers can also be used with the new white models.
USA - CMI Communications supported the stage production for a multifaceted event at the Minneapolis Convention Centre in August, where they utilised a large complement of Ayrton Ghibli LED spot luminaires to illuminate the Knights of Columbus 137th Supreme Convention. Sessions were broadcast internationally, and to over 1800 attendees of the event. The fixtures matched exactly in output and colour temperature even though they were supplied by three different vendors.
AV service provider CMI Communications of Rochester, New York asked Light and Shadow, LLC of Winter Garden, Florida to provide turnkey lighting design for the convention as the company has in the past. During the three-day event the daily morning Mass and business sessions were broadcast on EWTN, CatholicTV and other outlets. The convention hall featured a 120ft-wide stage with a 115ft projection screen as a backdrop.
“We needed a high-quality broadcast light that we could also use for the opening dinner,” says lighting designer, Shawn Seithel. “We were looking for a replacement for our previous go-to fixture, and a Ghibli demo by ACT Lighting sparked our interest.”
During the demo, “Ghibli did everything our usual go-to fixtures did and did it better. Ghibli was brighter, had a nice flat field and its framing shutters were a huge plus. It looked like a well-rounded light for every kind of event we do,” Seithel says.
For the convention Seithel rented 78 Ghibli fixtures from three vendors placing them on mid-stage and downstage truss and on two trusses running the lengt
USA - Nesta Garrick lights the Welcome to Jamrock Reggae Cruise, an annual December excursion that showcases many of the genre’s leading stars. But every year, the Jamaican-born LD disembarked from the floating festival’s ship with the same unfulfilled wish: he wanted an outdoor rated moving wash.
“I have been working on Jamrock for five years, going on six, and in that whole time I’ve asked myself ‘why can’t someone make a moving wash that’s IP rated?’” he said. “This is a five-day cruise, and every night we’d have to take our washes down, because it rains a lot at sea. Then, the next evening, we’d have to focus them manually, which was difficult given the short amount of time we had to set up.”
The owner of RAS Visuals & Lighting, Garrick was visiting LDI in 2018 when he came across the Chauvet Professional Maverick Storm 1 Wash. “Right then I knew I found my answer,” he said. “I called Abbas Ritscher from The Design Oasis and asked if he had the Storm 1 Wash. He told me he did, so here we are!”
When the stately Independence of the Seas set sail in the Caribbean on Welcome to Jamrock Reggae Cruise 2019, reggae stars like Stephen ‘Ragga’ Marley, Buju Banton, Popcaan and Taurus Riley were on board, so too were 12 Maverick Storm 1 Wash units, which like the rest of the fixtures in Garrick’s rig, were supplied and installed by The Design Oasis.
Although the issue of having to take down non-IP rated moving washes every night was resolved, Garrick had to contend with other challenges on board the vesse
USA - The new Christie Crimson Series of 3DLP laser projectors, introduced this week, deliver 31,500 ISO lumens for the same price as the Crimson 25 models with the same 60Hz processing and Christie BoldColor Technology in a compact, rugged package for rental, staging and fixed installation customers.
Users will also experience the same Christie TruLife electronics and the built-in warp and blend capabilities of Christie Twist. In addition, by adding Christie Mystique, users will reduce multiple projector calibration times from hours to minutes, saving both time and labour costs.
Designed with the technician in mind, the Crimson Series is built-tough and is easy to ship, handle and install thanks to its compact form factor, quiet operation and omnidirectional capabilities. Featuring an IP5X sealed, solid-state laser light source, Crimson projectors provide years of reliable, low-cost, and virtually maintenance-free operation while delivering vibrant, lifelike colours in theme parks, indoor and outdoor arenas and stadiums, entertainment venues, mega events, public spaces, and more.
“The new Crimson models – which are both upgradeable to 120Hz – support both Christie Guardian for real-time automatic blended-image correction when content is playing, and the Christie Terra input card for seamless integration into SDVoE networks,” said Mike Garrido, senior product manager, Christie. “We’ve designed it with 31,500 ISO lumens for the same prices as the Crimson 25 models, providing even greater value for our fixed install, rental and staging cus
UK - Lighting rental specialists Version2 supported The Brits Are Coming at the newly re-opened Riverside Studios. Working with award winning lighting designer Tim Routledge, the Version2 team supplied a comprehensive lighting package, including a healthy selection of recent additions to the company’s growing inventory.
The Brits Are Coming TV special is the reveal of the nominations for the BRIT Awards 2020. Hosted by broadcaster and presenter Alice Levine, the show featured special guest performances by nominated artists including Liam Payne, Aitch and Mabel.
Recorded for ITV in front of a live audience, this was one of the first and one of the largest productions staged within the newly opened Studio 3 at Riverside Studios. Following the extensive re-development of the historic West London site, Riverside’s hosting of the show conveyed a clear message that the production centre is back open and ready for business.
Commenting on working with Version2 at Riverside, Tim says, “I use V2 a lot for my broadcast work as they always go the extra mile and have a want to make a great show every time. This was also only the second show in the all new Riverside Studios which was a blessing - a fantastic new studio with a saturated overhead grid of lighting hoists and the ability to patch data anywhere, it was a really easy studio for this show to move to and it worked for us brilliantly.”
Over the past year V2 has been steadily growing their inventory to increase both the scope and range of products they have available. Ahead of t

USA - d&b audiotechnik has announced the introduction of a new addition to the company's exceptional SL-Series line array family. The KSL-SUB, available in both flown and ground stack (G) versions makes its debut at the 2020 Winter NAMM show in California this week.
The new KSL-SUB provides a small, lightweight format that extends the frequency response of a KSL System down to 36Hz with “exceptional dispersion control, impressive low frequency headroom and unmatched performance for its size”. This directivity-controlled, smaller format sub enclosure allows venues of all size to experience very accurate, smooth and punchy bass response, says the company.
The KSL-SUB and KSL-GSUB subwoofers operate with two forward-facing 15” drivers and a single, rear-facing 15” driver which, driven with two-way active amplification, provide uncompromised cardioid directivity control.
Measuring 100 x 90 x 45 cm (39.4” x 35.4” x 17.7”) in size, and with a weight of 82kg (181lb), the KSL-SUB delivers an output of 139dB driven by d&b D80 amplifiers.
The KSL-GSUB has a streamlined form: minus the KLS-SUB standard rigging hardware. It stands at a diminutive height of just about 45cm, easily allowing for under stage deployment. Using a new KSL-SUB adapter frame the KSL-SUB can be deployed above KSL-Tops as part of a flown array.
Completing the comprehensive System package - and designed to fit within standard sized shipping container and trucks - the KSL-SUB is available in touring carts with protective covers. The hybrid KSL-SUB touri
South Korea - Christie Digital reports that Gyeongnam Masan Robot Land, the world’s first theme park dedicated to intelligent robotics, has installed an extensive range of its laser projectors and real-time video processing and show control systems, which deliver spectacular visuals and enhance the visitor experience.
Located in the city of Changwon on the southeast coast of South Korea, Gyeongnam Masan Robot Land occupies 1.25m square meters and comprises a research and development centre, convention centre and theme park. Its main attractions, which combine robotics technology and entertainment, are powered by Christie GS Series and HS Series 1DLP laser projectors, as well as Christie Pandoras Box’s Single and Quad players, Dual and Quad OCTO Servers, Pandoras Box Manager and Widget Designer. These systems were installed by Christie’s Korean partners Star Networks and Digital Line Technology Group (D.L.T Group).
“As the first robot-themed attraction in the world, no effort was spared to deliver the best visual and audio experience to local and international visitors of Gyeongnam Masan Robot Land,” comments Seung Won Ham, head manager at Star Networks. “Christie’s laser projectors and image processing solutions have been the clear choice from the onset. Besides using high-performance projectors and media servers, we want to accomplish a fully integrated technology solution that the end user can confidently rely on. This decision resulted in the best outcome in terms of usability, performance, reliability and ease of maintenance.”
USA - Coda Audio has confirmed the sale of a range of systems, including its flagship AiRAY, to two leading production companies in the USA. Eastern Stage Productions (ESP) of New York and Technical Entertainment Services (TES) based in Florida, have both made significant investments in Coda’s technology.
The two companies enjoy a close relationship, often working together on major productions and combined to provide a Coda system for the Stereo Bloom Stage at the recent EDC Orlando.
Bill Danilesyk of ESP comments: “The high fidelity of the sound is amazing with the real game-changer being the DDP driver. You get the same amazing fidelity from the Coda system as you would from the highest quality hi-fi systems - getting that at much higher outputs blew my mind right away. You listen to music you’ve heard one thousand times and all of a sudden you hear new things. These kind of intricacies and this level of sonic detail is something that was totally missed before and it translates to the live stage. And the low-end? Well, the impact of the bass is phenomenal. Everyone at EDC was blown away by the sound.”
Luke Jenks, managing director of Coda Audio USA, adds: “We’ve witnessed a sustained growth in the sales of both live and installed systems across the US, confirming that the Coda message is being heard loud and clear throughout the industry. We’re very proud that our next generation technology is becoming the choice of more and more audio professionals, who, like TES and ESP, are taking full advantage of the benefits it can deliver.”<
The Netherlands - Visual design studio Tenfeet’s longstanding relationship with Dutch rockers BLØF resulted in some dazzling effects as the much-loved band played two sell-out gigs at Rotterdam’s 16,000-capacity AHOY Arena.
Tenfeet video programmer Pim Elberse specified and supplied two Hippotizer Boreal+ Media Servers - one main and the second as a full live backup machine - to handle pre-made content mixed with multiple effects and live feed blend. The content ranged from sweeping landscapes to computer-graphics, lyrics and pictures.
“We needed a system that could cope with various live feeds and feed a variety of content that was mixed with live, as well as control an SDI-matrix with 10 cameras on stage surrounding the band,” explains Elberse. “The Boreal+ provided total flexibility in combination with our Hog4 lighting console.”
Despite the large venue, BLØF’s stage was only 10m wide, designed for an intimate feel. The stage floor was transparent, with lighting fixtures beaming up from underneath. Behind the band was a large LED screen, rising from the stage to a height of 16m - almost to the ceiling. At each side of the stage, multiple trusses held the lighting and worked in collaboration with an LED strip around the LED wall to enhance the sense of height.
“The staging and rigging structure gave us the freedom to create unique looks for every song and unite set, light and video,” Elberse continues. “During shows, besides running the programmed cues, I’m always controlling content and effects to integrate the vide
Belgium - Het Kunstuur (the Art Hour) is a new ‘interactive’ gallery concept developed by art collectors and entrepreneurs Hans & Joost Bourlon, presented in the former Holy Ghost Chapel in the historical heart of Mechelen, Belgium.
Thirty-two Belgian paintings from the 19th century are displayed in three gallery spaces where their stories are told by a series of well-known Belgian personalities.
Creative lighting design and media specialist Painting with Light (PWL) was asked to manage and co-ordinate and design the technical systems and control for lighting, video, audio and humidity control for this intricate and unique project.
Visitors wear headsets and listen to an audio track as they move around the spaces, prompted to stop / move on cue to designated areas by the audio track, where they watch and listen as the AV effects play out. The walkthrough lasts an hour, which inspired the name.
PWL was asked onboard by concept designer Wouter Verhulst of King Concept who created the original idea and storyline with the Bourlon Brothers and designed the gallery layout.
The first phase of the design process saw the whole museum virtually created in WYSIWYG and presented as a VR experience to the project’s initiators.
The PWL team, under the creative direction of Luc Peumans, was led on site by Céline Cuypers who project managed delivery of the full technical design including the projection system, creative lighting, audio track and control, plus specification, procurement and commissioning of all equipment and its impleme
