SYSTEM OPERATION
Electronic Controller The NX242 Digital TDcontroller presets are precisely matched to the GEO S8-Series cabinets and include
sophisticated protection systems. Using GEO S Series cabinets without a properly connected NX242 Digital
TDcontroller will result in poor sound quality and can damage components.
HF Dispersion Configuration After quick release of the front grill from its fittings, the HF Waveguide can be configured for 80° or 120°
dispersion in the non-coupling plane.
Array Design Arrays of less than 4 GEO S805 will provide poor dispersion control and are not recommended or supported.
S805 and S830 cabinets, having tangent waveguides, can be mixed in the same array.
Sub-bass The GEO S805 can be used without the optional CD12 Hypercardiod Sub. In this case the NX242 can be used
in stereo. With the CD12 Hypercardiod Sub each Sub channel requires two NX242 outputs and the NX242 will
operate in mono.
Speaker Cables The GEO S805 are wired 1- & 1+ on both Speakon connectors; 2- & 2+ are not connected.
Rigging System See corresponding chapter of this manual.
