INTRODUCTION
AMPLIFIER MODULE
MODUS 4805LA, 4820LA, 118FSA active system display a high efficiency Class D power amplifier module with switching power supply
enclosed in a die-cast aluminium chassis. This permits to protect the electronics against dust, avoid any air loss through the controls - which
would cause annoying noises - and maximize health loss by using the woofer ventilation instead of a cooling fan.
MODUS is not just another line array in the market. It’s the essence of ideas and use of technologies condensed into one focus: the invention
of the most flexible sound reinforcement system able to satisfy the broadest applications, from live touring to permanent installation, without
compromising quality and expectations.
MODUS is a constant curvature line array system comprising two modules, the MODUS 4805 (5°V) and the MODUS 4820 (20°V), each one
equipped with 4 x 8" neodymium magnet woofers and 4 x 1" neodymium magnet HF compression drivers.
The system is designed to achieve a very uniform distribution of SPL in the listening area in both large and small venues thanks to its total
modularity. The constant curvature overcomes the limitations of line arrays with variable angles which inevitably create unmatched SPL
between neighbouring enclosures at high frequencies.
The grouping of two «classic» array modules in one gives an amazing economic advantage and simplifies the setup of the system.
Two subwoofers are available for low frequency extension, both with mechanical suspension hardware to deliver seamless integration:
The MODUS 215 FSA is a dual 15" subwoofer with a band-pass design and push-pull configuration, delivering significantly extended low
frequency response despite its compact size. It is acoustically designed to support two or three MODUS 4805 or 4820 modules.
The MODUS 118 FSA is a single 18" subwoofer with a bass reflex design and compact dimensions that make it ideal for suspension.
Designed to support one or two MODUS 4805 or 4820 modules and aesthetically similar to 4805 module, the sub is capable of very high SPL
in relation to its size. It can either be suspended above the line array modules or ground stacked; additionally, the 118 FSA can be used in
conjunction with the 215 FSA to further extend and reinforce low performance.
