In the calm and elegant modern interior of Willebadessen’s Baptist Church, a high-flying GEO M6 line array is almost invisible in its custom grey colours. The Church approached Kalle Hogrefe of Sound Linear, the Paderborn-based installation and rental company, to design a system that would provide smooth and even SPLs to each of the 1500 seats in the sanctuary.
After spending a test weekend with NEXO GEO M620 full-range cabinets, pole-mounted for the evaluation, a favourable decision was made. Hogrefe used NEXO’s NS-1 proprietary modelling software to design and specify a system which used 7x GEO M620 cabinets in L/R arrays, with a centre cluster of 3x M620s. For the choir, 3x PS10-R2 speakers were fitted behind the arrays. These were powered by 2x NXAMP4x1 amplifier/processors.
For aesthetic reasons, the Church wanted to make the system as low-profile and invisible as possible, so all speaker elements were painted in a soft custom grey colour which blends in with the décor. This includes two new ID24 super-compact speakers, which are being used as floor monitors on stage. These powerful twin 4” cabinets, the smallest ever to be made by NEXO, are paired with another new product, the DTD Controller: in a light 2U rack, this unit confers new affordability and accessibility on NEXO loudspeakers by connecting them to third-party amplifiers of every size and scale, in this case, an existing QSC amp.
OUT IN THE THEATRE
The Freilichtbühne Bellenberg is an outdoor Volkstheater, where all the performers are amateur, working with a professional director. With 850 seats in the venue, this long-established venue hosts standard theatre productions as well as musicals and shows for children.
In its search for a system, the venue staged a shoot-out between two famous French loudspeaker manufacturers. The members of the theatre club unanimously chose the NEXO GEO M620 because of its superior speech intelligibility.
Here too, Kalle Hogrefe of Sound Linear used the NS-1 modelling software to design the system, which deployed 6x M620 full-range modules plus 2x NEXO CD12 subs per side. The speakers are powered by 2x NXAMP4x1, mixed on a digital console.
The GEO M620 is a full-range unit for stand-alone, curved array or line array application. Extremely compact in size (191 x 373 x 260 mm), the M620 module weighs less than 10 kgs. Using a NEXO-designed long-excursion high-efficiency 6.5″ LF driver and a 1″ throat driver on a BEA/FEA optimised HR Wavesource, the M620 delivers a frequency response of 80Hz-19kHz ±3dB, with nominal peak SPL of 127dB. HF dispersion is 80° or 120° horizontal, with 20° vertical coverage, 0° to 20° splay when arrayed. Using NEXO’s HRW patented waveguide for optimum HF coupling between elements, the M620 performs in a variety of configurations, facilitated by a fully-integrated 3-point rigging system.
The ID Series ‘supercompact’ ID24 has a unique user-rotatable horn that lets users quickly select between 120° x 30° or 30° x 120° HF coverage, whether mounted horizontally or vertically. Measuring just 309mm wide, 132mm high and 233mm front to back, the ID24 uses twin 4 inch drivers in a V formation, and is ideal as a full-range speaker, or as a dedicated ‘sound beaming’ unit in difficult spaces.
