SYSTEM SPECIFICATIONS GEO T4805 WITH NX242 TDCONTROLLER
Frequency Response [a] 67Hz – 19kHz ± 3dB
Usable Range @-6dB [a] 60Hz – 20kHz
Sensitivity 1W @ 1m [b] 109dB SPL nominal – 107dB SPL wideband
Peak SPL @ 1m [b] Configuration dependent [d].
Dispersion [c] Coupling plane: not usable alone. Configuration dependent [d]. Non-coupling plane: 90°.
Crossover Frequencies 250Hz & 1.3kHz active
Nominal Impedance LF rear: 32Ω - MF/LF front: 32Ω - HF: 16Ω
Recommended Amplifiers HF: 3000Watts into ~3Ω/6 cabinets.
MF/LF (front section): 6000Watts bridged mono into ~6Ω/6 cabinets.
LF (rear section): 6000Watts bridged mono into ~6Ω/6 cabinets.
Electronic Controller The NX242 Digital TDcontroller presets are precisely matched to the GEO T Series cabinets
and include sophisticated protection systems. Using GEO T Series cabinets without
properly-connected NX242 Digital TDcontroller will result in poor sound quality and can
Dispersion Configuration The CDD is configured for 90° dispersion in the non-coupling plane.
Array Design Via GEOSoft compiled Matlab application or EASE/CATT .dII (latest version available at
Subbass CD18 Supercardiod SubBass (requires two NX242 outputs and two amplifier channels).
Speaker Cables LF rear: 1(-)/2(+) - LF/MF front: 3(-)/4(+) - HF: 5(-)/6(+).
Rigging System Please refer to the GEO user manual before any operation.
