Thank you for selecting NEXO GEO S8 Series products. This manual is intended to provide you with
necessary and useful information about your GEO System, which includes the following products:
• S805 5° Tangent Array Module. 8” (20cm) Neodymium Hi-flux 16 Ohm LF Driver and 1”
Throat Neodymium HF Driver on a 5° Hyperboloid Reflective Wavesource. Your main
building block for curved vertical tangent arrays; integral precision array assembly system.
• S830 30° Tangent Array Module. 8” (20cm) Neodymium Hi-flux 16 Ohm LF Driver and 1”
Throat Neodymium HF Driver on a 30° Hyperboloid Reflective Wavesource. The building
block for horizontal tangent arrays, and the tangent down-fill element for curved vertical
arrays; integral precision array assembly system.
• CD12 HyperCardoid Subbass. Two 12” (30cm) Long Excursion Neodymium 6 Ohm Drivers,
each controlled by one DSP channel, creating a 120° x 120° hypercardioid pattern. Can be
flown or ground-stacked.
• NX242 Digital TDcontroller. Provides comprehensive control of the above GEO S8 Series
loudspeakers in multiple configurations. For a complete description of this unit, please refer
to the NX242 User Manual. Please remember that the NX242 Digital TDcontroller’s DSP
algorithms and parameters are software and are updated regularly. Please consult the
NEXO web site (
www.nexo.fr
or
www.nexo-sa.com
) for the latest software releases.
• GEO Flying System. Coupled with the integral array assembly system on GEO S8 Series
cabinets, provides safe, flexible and simple means of flying GEO Tangent Arrays. NOTE:
GEO Tangent Arrays control the dispersion of acoustic energy with a high degree of
precision. Inclinometers and laser aiming devices are essential to ensure proper audience
coverage when hanging or flying a GEO Tangent Array.
• NS-1 Design Software. MATLAB based Windows software simplifies the design and
implementation of vertical tangent GEO arrays.
Please devote some attention to reading this manual. A comprehensive understanding of GEO
waveguide theory, tangent arrays, and specific features of the GEO S8 Series will help you to operate
your system at its full potential.
