SYSTEM OPERATION
Electronic controller The NX242 Digital TDcontroller (with NX-Tension Card) presets are precisely matched to the GEO D Series cabinets
and include sophisticated protection systems as well as advanced cardioid directivity DSP algorithms. Using GEO D
Series cabinets without a properly connected NX242 & NX-Tension Card will result in poor sound quality and can
damage components.
Array design Arrays of less than 3 x GEO D10 will provide poor dispersion control and are neither recommended nor supported.
Sub-bass GEO SUB directional sub extends system low frequency response down to 35 Hz
Speaker cables Active: 5(-) / 6(+): HF; 3(-) / 4(+):LF/MF Front ; 1(-) / 2(+): LF Rear.
Passive: 5(-) / 6(+): Not Connected; 3(-) / 4(+):LF/MF/HF Front ; 1(-) / 2(+): LF Rear..
Rigging System Please refer to the GEO user manual before any operation.
As part of a policy of continual improvement, NEXO reserves the right to change specifications without notice.
[a]
Response curves and data: anechoic far field above 200 Hz, half-space anechoic below 200 Hz.
[b] Sensitivity & peak SPL: will depend on spectral distribution. Measured with band limited pink noise.
Refers to the specified +/- 3 dB range. Data are for speaker + processor + recommended amplifier combinations.
[c] Directivity curves and data: 1/3 octave smoothed frequency response, normalized to on-axis response. Data obtained by computer processing of off-axis
response curves.
[d] Please refer to the GEO D user Manual.
Usable range data: frequency response capability with TD crossover slopes removed.
