Page 2/112 INTRODUCTION GEO Technology is radically new thinking The GEO R&D Project has, to date, resulted in the following patent applications: • The GEO Hyperboloid Reflective Wavesource™ differs radically from the megaphone-variant type horns you know and love (or hate). “Tried and true” methods will produce entirely unexpected results. HRW technology produces precise and predictable results. • The Configurable Directivity Flange. A waveguide that allows the operator to alter its behaviour.
INTRODUCTION Page 3/112 SAFETY ISSUES IMPORTANT NOTICE CONCERNING HIGH SOUND PRESSURE LEVELS Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. The U.S.

Page 12/112 2 GEO S12 GENERAL SET-UP INSTRUCTIONS GEO S12 GENERAL SET-UP INSTRUCTIONS 2.1 Speaker connection 2.1.1 GEO S12 connectors GEO S12 is connected with Speakon NL4FC plugs (not supplied). A wiring diagram is printed on the connection panel located on the back of each cabinet.The 4 pins of the 2 Speakon sockets identified in / out are connected in parallel within the enclosure.
GEO S12 GENERAL SET-UP INSTRUCTIONS 2.1.4 Page 13/112 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 mm2 (AWG #12) cable length Lmax for such a cluster is 10 meters. IMPORTANT Long speaker cables induce capacitive effects – up to hundreds of pF depending on the quality of the cable - with a high-pass effect on high frequencies.
Page 14/112 3 AMPLIFIER SELECTION FOR USE WITH GEO S12S AMPLIFIER SELECTION FOR USE WITH GEO S12S 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.
AMPLIFIER SELECTION FOR USE WITH GEO S12S Page 15/112 • Some amplifier brands have an identical input sensitivity for models of different power rating (this infers a different voltage gain for each model). For example, a range of amplifiers with different power outputs, all having a published input sensitivity of 775mV/0dBm or 1.55V/+6dBm, will have a wide range of actual gains – the higher the power, the greater the gain.
Page 16/112 AMPLIFIER SELECTION FOR USE WITH GEO S12S IMPORTANT When in Bridge-Mono mode, check your amplifier user manual for proper connection of outputs 1(+) and (2+) in relation to input phase. • Parallel-mono: the output terminals of the two channels are configured in parallel using an internal relay. The (single) load is connected either to the output of channel 1 or to that of channel 2 (as if in stereo).

Page 28/112 6 GEOSOFT2 GEOSOFT2 GEOSoft2 software is a R&D simulation tool derived application. It processes measured speaker data with complex mathematical algorithms to assist the user in designing vertical GEO Tangent Arrays that provide even SPL throughout the depth of the audience.
CONFIGURABLE DIRECTIVITY DEVICE 7 Page 29/112 CONFIGURABLE DIRECTIVITY DEVICE The GEO Wavesource controls dispersion of acoustic energy using an hyperboloid acoustical reflector in the “coupling plane” (the vertical plane of a curved vertical tangent array) and a diffraction slot in the “non-coupling plane” (the horizontal plane of a curved vertical tangent array). The patented Configurable Directivity Device consists of bolt-on flanges that alter the diffraction slot’s exit flare rate. 7.
Page 30/112 7.2 CONFIGURABLE DIRECTIVITY DEVICE When & where to use Configurable Directivity flanges The diagrams show audience area coverage for a stereo system. While the GEO cluster will deliver even SPL from the front to the rear of this audience area, there are “holes” near the front in the centre and at the outside edges. We cannot fill the outside coverage gaps without enlarging the centre gap, and vice versa (left figure below).
GEO S12 HARDWARE SETUP PROCEDURE 8 Page 31/112 GEO S12 HARDWARE SETUP PROCEDURE Before proceeding with assembly of GEO S12 arrays, please ensure that the components are present and undamaged. A component list is appended to this manual. In the event of any shortage, please contact your supplier. For maximum efficiency the GEO S12 rigging system requires three experienced persons for set-up: typically one motor hoist operator, and one GEO S12 operator per side of the array.
Page 32/112 8.1.2 GEO S12 HARDWARE SETUP PROCEDURE • Ensure that public and personnel are not allowed to pass beneath the system during the installation process. The work area should be isolated from public access. • Never leave the system unattended during the installation process. • Do not place any object, no matter how small or light, on top of the system during the installation procedure. The object may fall when the system is flown and is likely to cause injury.
GEO S12 HARDWARE SETUP PROCEDURE 8.1.3 Page 33/112 Contacts Correct training is fundamental to safe practise when working with loudspeakers flying systems. NEXO recommend that users contact local industry associations for information on specialist course.

WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
Page 70/112 NEXO ANALOGUE GEO S12TD CONTROLLER CAUTION! This servicing instruction is for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. 9.3.5 Recommendations for wiring the sense lines The impedance of the sense inputs of the TDcontroller are high, so currents are low and therefore light duty cable can be used.

It is sometimes claimed that connecting cable shield at both ends creates ground looS12, and that the current flowing in such looS12 will produce noise. This is not the case for most professional audio equipment.

All available GEO S12 setups require that NX-ES4 card is installed in NX242 TD Controller. 10.1 NX242 Proprietary Functions The NX242 is much more than a “generic” Digital Signal Processor.

NEXO NX242-ES4 DIGITAL CONTROLLER FOR GEO S12 Page 79/112 10.2.5 Delays Multiple NX242’s can be used on a single GEO S12 array. When changing the delay in one NX242 TDcontroller that is part of a multi-controller system, take great care to have exactly the same delay setting in all NX242 TDcontrollers that receive the same input signal (i.e. all NX242’s that are fed from the Left output of the mixing console should have the same delay settings).
Page 80/112 SYSTEM ALIGNMENT GUIDELINES 11 SYSTEM ALIGNMENT GUIDELINES The NX242’s factory delay presets are optimised to provide the best possible crossover between the GEO S12 and CD18 / S2 / GEO SUB systems. The reference point for this adjustment is the front of each cabinet. (This means that the internal delays needed to achieve a correct time alignment are set for cabinets standing next to each other with both fronts aligned).
SYSTEM ALIGNMENT GUIDELINES Page 81/112 11.3 Driving the GEO SUB’s from the AUX send It is quite common to use the AUX send of a mixing desk to drive the Sub section of a PA system. This gives the mixing engineer more flexibility to set the level of the subbass relative to the main PA, apply special effects, or to use a different EQ on the Sub. However, it also raises some serious issues for the performance & safety of the system (mostly time alignment).

GEO S12 – RS15 / CD18/S2/GEOSUB SYSTEM CHECK LIST Page 83/112 12 GEO S12 – RS15 / CD18/S2/GEOSUB SYSTEM CHECK LIST It is essential to execute all these check steps prior to perform a sound check on the “front end” to the system. Following this checklist step by step will prevent many troubles and will save time in the end. 12.1 Are the NX242 Digital TDcontrollers properly configured? IMPORTANT If you must change any of the parameters listed above, make sure that you use the same values on all NX242’s.
Page 84/112 GEO S12 – RS15 / CD18/S2/GEOSUB SYSTEM CHECK LIST 12.4 Are the speakers properly connected and angled ? • Attach the first series of modules to the bumper. • Before flying, verify that all channels of all modules are functioning properly. • Make sure that each RS15 / CD18 / GEO SUB is producing the proper front/rear summation: when listening from behind the array, switch the front drivers in and out.
