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¥Ø. |
Recommended amplifiers |
2 amplifier channels are required for directional operation, each rated at 1000 to |
|
2000Watts into 8¥Ø 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. |
