Since the beginning, the goal of most line array manufacturers has been to build a one cabinet model that could cope with all kind of events. Very big and heavy designs have been unable to avoid the use of extra subs. So why rig those huge systems housed with 15” and 18” units if in the end, extra subs, usually not hung, are required? Moreover, the technology employed brings extra on- stage problems with undesirable bass excess headroom. Another complication, not well-solved, is the need for specially developed loudspeakers to cover the front fill situations. More loudspeakers have to be used, with different signal processing, so in the end we find that systems become more complex and less flexible. To bring forward a total solution to fix all these in a simple way is not easy, but the LA312 has enough new solutions to clear up things and make the job of sound engineers easier. First of all we have established a design criterion in which the size of the cabinet is extremely compact. The bass section consists of two 12” drivers coupled to a low flare folded horn. A horn always has the benefit of better control the pattern in which the sound is projected, avoiding the headroom bass problems on stage. The coherent sum of the mouths’ outputs of all the enclosures of the array extends the low frequency response (i.e. 46Hz–3dB for an 8 array element). Nowadays for events in which very low frequency performance is needed, the use of extra subwoofers will be required. For the mid frequencies reproduction, the LA312 uses one very high output 12” neodimium loudspeaker, coupled to a phase corrector device that evenly spreads its response all over the mouth of the horn. That is fundamental for every well designed line array to avoid combing situations. High frequency is handled by two 1.4” exit compression drivers attached to a pattern controlled (85º horizontal x 8º vertical) symmetrical curved wave guide, coupled to a non resonant horn. The system’s shape is trapezoidal, so we can better angle and focus its elements. This feature could partially solve front fill applications, if the front fill focused elements could be managed independently apart from the other elements of the array. That can be done with the LA312, as each loudspeaker is individually DSP controlled by its own digital processor. Every LA312 has built into it the amplifiers and digital control required to vary each of the features of the enclosure. This performance give us the possibility to program air absorption correction, modified eq’s and gain for front fill situations, directivity control... and all the parameters we need to optimize the overall performance. The LA312 has built in proprietary hardware for simple, fast and safe rigging. The enclosure has been made with the latest techniques assuring a perfect and rigid construction. Weatherized finish is provided, as the cabinet is covered with rugged Durawound texture finish and protected with epoxy powder coating grills. With the mouse of a small laptop, the sound engineer can vary in real time, any of the parameters on each of the speakers. After starting TECNARE software, the system will identify the speakers connected to the net, showing them in the network window of the program. You only have to choose the speaker to be managed, and six different windows will be available for the sound engineer to control everything.
