SL 210 A is a self-powered two-way line array with remote monitoring, fully developed by the engineering team of WORK PRO at our installations in Valencia (Spain). It features two 10'' transducers and one 1.46'' voicecoil in a bass reflex enclosure. The  two  low pass cut-off  frequencies  in  the  loudspeakers contribute to an even horizontal directivity.

The high frecuencies are reproduced by a 1.4'' exit compression driver which features a polymer PM-4 membrane, which brings a more natural sound when compared to other materials commonly used.  The  compression  driver radiates over the new  VI-10 waveguide which provides a perfect vertical coupling between the high frequencies of the different SL 210 A units.

The digital signal processing, the passive mid-frequency attenuation in one of the speakers and the new OP-120 horn are carefully designed to provide excellent uniformity of the horizontal coverage, keeping the frequency balance unchanged at the listening angles.

SL 210 A features a powerful digital signal processing, which provides the filtering and the necessary corrections of magnitude and phase to the transducers in order to obtain a faithful sound depending on the number of units used. Both from the monitoring software, via Ethernet, and from the keyboard and screen on the rear side, you can choose the compensation preset by number of units, add delay and use up to 8 parametric filters for room corrections.

The power is provided by two Class D amplifiers with 1000W peak for the Low frequencies and 500W peak for the Highs, which incorporate thermal and overload protections and universal switched power supply. The protection of the transducers is given by the DSP, with independent RMS and peak limiters for each way.

The main part of the SL 210 A enclosure is made of 15mm birch plywood and finished in black paint with high durability, while the sides are made of high resistance ABS plastic and have a handle on each side that is adequately dimensioned to allow grip comfortable and safe. The connectors, the keyboard and the high visibility LED screen are on the back, easily accessible while protected from accidental shock.

A 2mm thick perforated steel grille protects the transducers from occasional shocks during transport and normal use of the equipment. The grille is covered by a scratch-resistant fabric. In addition, it protects from water, it is aesthetic and acoustically transparent. The robust and precise rigging system is constructed of stainless structural steel and has been specially designed to be easy to assemble. The system incorporates 12mm diameter safety pins.
