The Ikarray-12sp is an innovative 2-way self-powered bi-amping, full range line-array with 12"/ 1.4" neodym drivers, an internal 3.2 kW power amplifier module and the DSP loudspeaker management system with extensive features. The DSP has high computing power and all the standard controller functions.
The integrated amplifier and DSP blocks used are identical to the HDSP amplifiers and the VA-WLAN remote software. The Ikarray-12sp and Ikarray-12 are compatible and can operate together. They provide the same 100% performance, and the same control and monitoring software in a combined software network.
The Ikarray-12sp is a plug and play speaker. All required settings for different configurations are stored as factory presets in the internal memory. For best performance and reliability, simply select the corresponding preset on the Display for use as either, a stand-alone full-range speaker, or a top speaker with bass support, or a monitor on stage, or with multiple units flown in an array. There are still a number of other features, options and access settings available for the experienced technician and professional audio user.
On the back is a special built-in Display button and Encoder control wheel. It is possible to access almost all the parameters without PC control and the functions can be locked and password protected. The Display has a 2-stage dimmer and can also be switched off completely to prevent unwanted stray light on, or beside, stages. By pressing a key or the encoder, the Display activates again.
The active electronics are convection cooled by a large heatsink and are maintenance free. No dust or moisture can be sucked or drawn in, making the Ikarray-12sp ideal for permanent installations. The robust cooling fins are amply rounded and have no sharp edges.
Much emphasis has been placed on constant directivity and linear frequency response even outside the mid-axis. This has been achieved on the horizontal level with one 12-incher, single mounted to give a wide dispersion without restrictions such as those caused when two transducers are placed next to each other (d’appolito effect).
The vertically optimal coupling of elements is possible due to the tight spacing and division of the acoustic centers into multiple virtual sound sources: a 1.4" exit high frequency driver is coupled on a special Double-Twin waveformer, which splits the sound source into 4 subsections. A newly developed V-plug has been mounted in front of the 12" low-mid transducer to segment the large membrane into two sections, shifting the acoustic center outwards. The Double-Twin waveformer and V-plug make it possible to reduce the distance between the acoustic sources to a minimum, optimizing the frequency cut-off and the coupling. This technology has made it possible to use a 12" transducer in 2-way operation in compliance with physical laws to achieve a typical coherent line-array vertical wavefront.
In comparison to many other arrays of this size, the Ikarray-12 has a warm sound with powerful low-mids that allow a low x-over. As a result, the Ikarray-12 can be used for many purposes without subwoofers.
With completed dimensions of only 60.5 cm, the Ikarray-12 keeps within the advantageously trucking dimensions and is world-wide the narrowest in the 12"/1.4" class. Used in the ground-stack position on the upright Paveosub-218, which has the same width, it exhibits an elegant silhouette and giving an optical unity.
The splaying between the individual Ikarray units is achieved by an innovative infinitely adjustable spindle mechanism. This enables more precise adjustment and optimization of acoustics than has been possible up to now with traditional locking-pin rigging systems. As an additional feature the fine adjustment of the mechanism can also be done under load.
For changing an angle between the elements the complicated unloading and de-rigging of the array become unnecessary. This saves a lot of time and makes work easier. Outriggers with adjustable feet can be mounted on the Rigging frame for ground stacking without subs. To create a sleek and discreet look, the line-array locking pin connection has been sunken into the loudspeaker body without extending parts.
A single unit can be directly mounted on a pole or tripod without a frame and can be adjusted. For this purpose, a pan-tilt box flange has been integrated into the floor of the box. For smaller venues with only one or two flying arrays, neither the larger rigging frame nor any other specialty parts are needed. For this purpose, the Ikarray-12 is equipped with the specially designed VA-flying tracks that click into the elegant Easy-fly mechanism – also used in the modular series.
The sum of its innovations and detail solutions make the Ikarray-12 a very scalable, universal, compact and powerful sound tool.
