AUSTRALIAN MONITOR NRG500 User manual

NRGSOO
The NRG500 is a high power fullrange 2 way passive loud-
speaker system designed for a multitude of critical profes-
sional audio applications where compact size, low distor-
tion and high output capability are the major considerations.
The compact size and the 30 degree trapezoidal cabinet con-
struction, allow for easy flying of multiple array groups to
form side or centre clusters in confined areas, with well con-
trolled accuracy and predictable dispersion characteristics.
Avoiding the need for ancillary control electronics, the pas-
sive NRG500 provides high dynamic, high efficiency out-
put from an ultra compact enclosure. The two way system
utilizes a proprietary 380mm (15") low frequency driver
combined with a 25mm (1") compression driver mounted
on a 90 x 40 degree constant directivity horn,
Complex and robust in design and construction, the unique NRG500 T.{etwork Manager' provides equalization
for both, horn / compression driver resonance and power response in the constant directivity horn. Accurate
filtering allows for a smooth transition between low & high frequency drivers at the critical crossover point. The
resulting smooth frequency response and phase coherence provides well defined clarity and detail.
The low frequency section is designed to a stable QB3 alignment giving excellent transient response and provid-
ing the ability to handle heavy bass equalization. This alignment allows higher displacementlimited power han-
dling than typical ported cabinets hence the massive power rating for a single 380mm (15") system.
The NRG500 is fabricated from high density plywood with internal bracing, it comes supplied as standard with
two heavy duty steel bar handles and stand mount. The steel grille is powder coated for durability and the enclo-
sure is finished in heavy duty black carpet with steel protective corners. Flyrng points are an available optional.
