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
S805 and S830 cabinets, having tangent waveguides, can be mixed in the same array.
Sub-bass
The S830 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 S830 are wired 1- & 1+ on both Speakon connectors, 2- & 2+ are not connected.
Rigging System
See corresponding chapter of this manual.
