The central conference hall at the Moscow head offices of the Mosenergosbyt
Russia - A recent upgrade of AV systems in the central conference hall at the Moscow head offices of the Mosenergosbyt AO energy company – the largest wholesale energy company in the Russian Federation – saw the installation of an Amate Audio Xcellence X208 line array, providing the complete audio reinforcement for the 180 seat auditorium.
Charged with bringing the company’s principal conference facility into the 21st century, system integrator Atanor group – an Amate Audio authorised distributor in the Russian Federation – opted to ensure even distribution of high intelligibility audio signals throughout the auditorium by means of a line array.
The X208 was chosen as providing a highly efficient, effective and compact solution by virtue of its novel coupling of X208A active and X208P passive array elements, where power and DSP loudspeaker system management is provided by the X208A in a line array combining both models.
In this application, left and right strings of one X208A and three X208P elements provides 3000 W a side of Class D bi-amplification, with specific system control presets for that particular cabinet configuration. Additional tuning of the system, once flown, was achieved via Wi-Fi with Amate Audio’s DSP Studio control software.
Atanor’s Alexey Dumchev explains, “One of the tasks was to improve the sound coverage of the room, to create a fully uniformly covered acoustic space. For this purpose, new line arrays from the Spanish manufacturer Amate Audio were chosen – the Xcellence X208A and X208P. The line array strings were flown with the Amate Audio TA-X208R touring bar, on steel cables from the ceiling, at the edges of the stage.”
The Xcellence X208 is a two-way line array, incorporating two direct radiating 8” loudspeakers with a 2.5-inch voice coil, in a cabinet designed around Amate Audio’s proprietary high performance 110o x 11o aluminium long throw waveguide, coupled with two 1.7” voice coil diameter, PEN diaphragm, neodymium compression drivers.
The waveguide provides consistent levels of frequency response over greater distances than is usual with a compact line array design. This greatly increases the breadth of applications in which the system can be deployed, says Amate.
