Low Noise Emissions from Proel plus an active Axiom
Proel’s LNE Systems are aiming for applications that require high performance in terms of sound pressure and audio quality but a tightly focused coverage pattern producing minimal overspill. The LNE (Low Noise Emission) range comprises two ceiling speaker models in the shape of the SC965P and DS112P.
The SC965P is a modular ceiling speaker designed using CAE/CAM, making up the basic element of the Proel Modular Matrix Speaker System. Each 60 x 60 cm module features nine high-excursion 6.5-inch wide-range speakers, including a demodulating ring at the base of the magnetic circuit to deliver very low distortion levels. Thanks to the speaker serial connection, the module features 400W (AES) power handling over 32-Ohm. Electronic protection is also onboard.
High directivity is achieved via the manipulation of the source interaction, resulting in minimised overspill – the greater the area size, the greater the effect. Modules can either be suspended side by side using inbuilt connection points to create the appearance of a false ceiling, or with optional flying hardware.
Meanwhile the DS112P is a two-way, full-range system intended to provide reinforcement in limited areas while again avoiding overspill. According to the manufacturer, it can be ‘integrated in any type of ceiling, wall or roof, both indoors and outdoors’.
The system – housed in steel and IP55 rated – boasts 300W (continuous) power handling on 8-Ohm, is equipped with custom-designed transducers, and reportedly control directivity down to 500Hz despite its compact dimensions. It is particularly effective in localised speech applications and has been designed to operate on the vertical axis, from top to bottom, so that its coverage area is identified in the space below it, within a cone of approximately 80-degrees. Outside of this area, the sound level is reduced by as much as 15-20dB.
Also recently announced by the manufacturer is an active version of the Axiom 2010A vertical array system.
Axiom 2010 was originally announced in 2012, comprising the 10-inch AX2010 vertical array element and the double 18-inch SW218 subwoofer, both of which are based on the concept of Acoustic Transmission Line, replicating in the speaker cabinets what happens in human ears. The sound reproduced by the transducers travels through a transmission path without resonance phenomena, resulting in natural sound, clean basses and very high efficiency. This concept is applied not only to the cabinets, but also to the HF wave-forming device.
The active version of the system has been equipped with Proel’s ‘most advanced electronic technology’. That includes Class-D DA Series digital power modules delivering a maximum power of 2000W for the AX2010A (one module) and 4000W for the SW218A (two modules), and the SHARC –based Core digital signal processing (also found in the PC series of loudspeaker processors and the Neos AXS series of active speakers). Core DSP offers 40-bit, 96kHz floating point resolution and 24-bit AD/DA converters plus a dynamic range in excess of 110dB.
