Please consult the NEXO web site (www.NEXO.fr or www.NEXO-sa.com) for the latest software releases. Please devote your time and attention to reading this manual. A comprehensive understanding of GEO theory, tangent arrays and specific features of GEO S12 will help you to operate your system at its full potential.

  • Page 12: Geo S12 General Set-Up Instructions

    2.1.3 Cabling NEXO recommends the exclusive use of multi-conductor cables to connect the system: the cable kit is compatible with all the cabinets, and there is no possible confusion between LF, MF and HF sections. Cable choice consists mainly of selecting cables of the correct sectional dimension (size) in relation to the load resistance and the cable length.

  • Page 13: Example

    GEO S12 G Page 13/112 ENERAL NSTRUCTIONS 2.1.4 Example: • GEO S12 has a 16 Ohms nominal impedance in passive mode, so 4x Geo S12 wired in parallel will present a 16/4 = 4 Ohm load impedance. The maximum acceptable 2x2.5 mm (AWG #12) cable length L for such a cluster is 10 meters.

  • Page 14: Amplifier Selection For Use With Geo S12S

    MPLIFIER ELECTION FOR USE WITH NEXO recommends high power amplifiers in all cases. Budget constraints are the only reason to select lower power amplifiers. A lower power amplifier will not reduce the chances of driver damage due to over-excursion, and may actually increase the risk of thermal damage due to sustained clipping. If an incident occurs on an installation without protection, the fact that amplifiers only generating half their rated output power (-3dB) are used will not change anything in respect of possible damage.
  • Page 15 Remember that constant sensitivity settings will give a different gain value when the amplifier power is different. NEXO recommends low gain amplifiers: +26dB is recommended, as it is at the same time adequately low and quite common amongst amplifier manufacturers. This gain setting improves signal to noise ratio and allows all preceding electronic equipment, including the NX242 TDcontroller or GEO S12 TDController, to operate at optimum level.

  • Page 16: Example

    These functions are not adapted to specific system requirements and may interfere with the complex protection algorithms used in the NX242. NEXO do not advise using other protection systems in conjunction with the NX242 and they should be disabled.
