The compact, 2-way Nexo GEO S1230 is a scalable line array module that displays exceptional MF-LF output (103dBSPL nominal sensitivity -1W @1m) from a single12 inch loudspeaker and NEXO’s proprietary Directivity Phase Device (DPD). A narrow-Q (30°) device in single-source mode, S1230’s unique Hyperboloid Reflective Wavesource (HRW) allows coupled S1210/1230s to radiate as coherent, wavefronts, yeilding precise pattern control in vertical or horizontal arrays. S12 arrays display traditional "tight-pack" pattern control in the non-coupled plane.

The 30° vertical dispersion angle of the S1230 make it particularly suitable for nearfield coverage when angled down at the bottom of the array. It is also useful for creating horizontal arrays allowing wide horizontal dispersion from a few modules.

Coupled MF/HF pattern control is array-dependent, as designed by GEOSoft2 array software. Non-coupled MF/HF coverage is adjustable, via NEXO’s patented Configurable Directivity Device (CDD) flanges, at either 80° or 120°. Comprehensive hardware accessories, for both fixed and mobile systems, optimize inter-cabinet angles and rigging. NEXO’s NXAMP TDcontroller maximizes S1230’s MF/HF coherency while providing EtherSound network control.

Electronic Controller NEXO TDcontroller presets are precisely matched to GEO S12 Series cabinets and include sophisticated protection. Using GEO S12 Series cabinets with improperly connected TDcontrollers will result in poor sound quality and can damage components.
Array Design Arrays of less than 4x GEO S1210 will provide poor dispersion control and neither recommended nor supported.
Sub-Bass RS15 / CD18 / GEO SUB / S2 extend system low frequency response down to 35Hz / 32Hz / 38Hz / 32Hz.
Speaker Cables Active: 1-/1+:LF; 2-/2+: HF / Passive: 1-/1+: Not Connected; 2-/2+:LF + HF.
Rigging System Please refer to the GEO S1230 User Manual before operation.
