General Description
l 90° Horizontal Coverage maintained
The LA212X is 3-way fully horn-loaded, axially symmetric, line array element, capable of producing crystal clear, detailed and extremely powerful audio performance over distance, with an exceptional 90° horizontal constant dispersion control. Being completely symmetric this line array is capable of generating virtually identical acoustic sound patterns on the right and left which allows for an easy, accurate and symmetric alignment. It incorporates a number of technologies to produce a coherent vertical wave front, extreme sound pressure levels with exceptional accuracy and specially consistent horizontal coverage over a wide frequency range, kept down to 280 Hz. Maintaining directionality control over this wide bandwidth raises the ratio of direct-toreflected energy, thereby increasing system intelligibility. The bass section makes use of two 12 inch speakers with 3 inch voice coils strategically placed on either side of the speaker in a dipolar horn arrangement. The, also horn-loaded, mid and high frequency sections are coaxially mounted in the center of the cabinet, dramatically extending lower vocal directivity control and providing extremely smooth mid/high transition. The generously dimensioned mid frequency horn uses a 10 inch driver, while the high frequency section consists of two 1.4 inch exit HF compression drivers with 2.5 inch voice coils mounted to a dedicated wave-shaping device. To preserve the acoustical integrity and the natural warmth, all the horns, wave guides and phase correctors are made of low resonance plywood or acoustically neutral polymers. The speaker transducers employed are exclusively made by the reference European manufacturer, B&C. The LA212X cabinet is constructed from genuine Baltic Birch plywood and has a black textured finish. The front of the loudspeaker cabinet is protected by a rigid metal grill and the side and rear panels incorporate four handles. Two Neutric NL8 connectors wired in parallel are mounted at the rear.
down to 280 Hz l Fantastic solution for large difficult
reverberant environments l Easy and fast rigging system with
variable splay angles from 0° to 8° l Dedicated Subwoofer and Power

Technical Data Sheet Architects’ and Engineers’Specifications The 3-way, full-range array module loudspeaker shall consist of two (2) 12-inch cone transducers with 3-inch voice coils for the lowfrequency section, one (1) 10-inch cone transducer with 2.5-inch voice coil for the mid-frequency section and two (2) 1.4-inch titaniumdiaphragm compression drivers for the high-frequency section. All the drivers shall be horn loaded and mounted in a coaxial arrangement . This technology will provide acoustic summation that is free from significant peaks or dips in response, from 60Hz to 19kHz, with effective pattern control to approximately 280Hz. The array module will require external, active digital signal processing for transducer crossover, frequency response equalization, time correction and dynamics control. The array module loudspeaker shall meet the following performance specifications: On-axis system frequency response shall be 60Hz to 19kHz (+/- 3 dB) with recommended audio processor (NEXT LMS242). The low-frequency sensitivity shall be 106dB SPL in halfspace with 1W input and be capable of producing peak output of 141dB SPL on axis at 1 meter, with recommended equalization. The mid-frequency sensitivity shall be 112dB SPL in half-space with 1W input and be capable of producing peak output of 142dB SPL on axis at 1 meter, with recommended equalization. The high-frequency sensitivity shall be 113dB SPL in half-space with 1W input and be capable of producing peak output of 141dB SPL on axis at 1 meter, with recommended equalization. The low-frequency section shall have a continuous power handling rating of 1600W and a nominal input impedance of 2 x 8ohms. The mid-frequency section shall have a continuous power handling rating of 500W and a nominal input impedance of 16ohms. The high-frequency section shall have a continuous power handling rating of 320W and a nominal input impedance of 16 ohms. Power handling will be rated as the double of the Nominal Power Handling (according to the AES2-1984 standard), and will be the recommended amplifier power in order to fully exploit the thermal and mechanical capabilities of the transducers The nominal coverage pattern shall be 90° horizontal and 8° vertical. The array module loudspeaker shall be constructed of 15mm 13-ply Baltic birch plywood, protected by a polyurethane coating, with integral steel rigging hardware. The rigging hardware shall support up to 18 similar array module loudspeakers with a 5:1 Safety Factor. The loudspeaker cabinet will be protected by 1.5 mm perforated steel grille with powder-coated finish. Input connectors shall be two (2) parallel-wired Neutrik® NL8 Speakon® connectors. The finish will be black (paintable). Loudspeaker dimensions shall be 1020 x 380mm x 500 mm and net weight shall be 61 kg). The 3-way, full-range array module loudspeaker shall be the NEXTproaudio LA212x.
