Dispersion [c]
Cardioid pattern over the entire useable bandwidth
(two channels of the NX242 are used for the process).
Directivity Index [c]
Q = 4.3 & DI = 5.3dB over the entire useable bandwidth.
Crossover frequency
X-Over Mode = 75Hz active / Overlap Mode = 300Hz through NX242 Digital TDcontroller.
Nominal impedance
2 x 8
Ω
.
Recommended amplifiers
2 amplifier channels are required for directional operation, each rated at 1000 to
2000Watts into 8
Ω
per channel.
SYSTEM OPERATION
Electronic Controller
The NX242 Digital TDcontroller presets are precisely matched to the GEO SUB and include
sophisticated protection systems. Using the GEO SUB without a properly connected
NX242 Digital TDcontroller will result in poor sound quality and can damage components.
Speaker Cables
The front loudspeaker of the GEO SUB is wired 2+ & 2- while the rear loudspeakers
are wired in parallel 1- & 1+. The GEO SUB must use separate cables from the main system.
Rigging System
Please refer to the 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 400Hz, half-space anechoic below 400Hz.
Usable range data: frequency response capability with TD crossover slopes removed.
[b] Sensitivity & peak SPL: will depend on spectral distribution. Measured with band limited pink noise.
Refers to the spe/- 3dB range. Data are for s pro 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.
