RS18 WITH NX242-ES4 TDCONTROLLER OR NXAMP SYSTEM SPECIFICATION

Omni :

• Frequency Response @ -3db [a] : 31Hz–100Hz
• Usable Range @ -6db [a] : 29Hz–200Hz
• Sensitivity 1W @ 1m [b] : 107dB SPL Nominal
• Peak SPL @ 1m [b] : 143–146dBPeak (2x1750W to 2 x 4000/8Ω)
• Dispersion : Omni & Directional pattern over the entire useable bandwidth depending on the NX242ES4 or NXAMP TDcontrollers setup. (two channels of the NX242 or NXAMP are required to process directional setups)
• Directivity Index [c] : 1.5<Q<2 1.7dB<DI<3dB
• Crossover Frequency: NX242 or NXAMP TDcontrollers preset dependent : From 75Hz to 100Hz
• Nominal Impedance : 2 x 8Ω
• Recommended Amplifiers : 1 amplifier channel is required for omni mode operation, rated at 3500 to 8000 Watts into 4Ω

Directional : 

• Frequency Response @ -3db [a] : 31Hz-100Hz
• Usable Range @ -6db [a] : 29Hz–120Hz
• Sensitivity 1W @ 1m [b] : 105dB SPL Nominal
• Peak SPL @ 1m [b] : 140–143dBPeak (2x1750W to 2 x 4000/8Ω)
• Dispersion : Omni & Directional pattern over the entire useable bandwidth depending on the NX242ES4 or NXAMP TDcontrollers setup. (two channels of the NX242 or NXAMP are required to process directional setups)
• Directivity Index [c] : Q=4.3 DI=5.3dB
• Crossover Frequency: NX242 or NXAMP TDcontrollers preset dependent : From 75Hz to 100Hz
• Nominal Impedance : 2 x 8Ω
• Recommended Amplifiers : 2 amplifier channels are required for directional mode operation, each rated at1750 to 4000 Watts into 8Ω per channel

SYSTEM OPERATION

• Electronic Controller : NX242ES4 Digital TDcontroller & NXAMP Powered Digital TDcontroller presets are precisely matched to RS18 and include sophisticated protection systems. Using RS18 without a properly connected TDController will result in poor sound quality and can damage components.
• Speaker Cables : 1-/1+ = Right or Rear / 2-/2+ = Left or Front / RS18 must use separate cables to the main system
• Accessories : Bumper – Flying Plates – Handles – Dolly – Front Wheel Board
• Rigging System [d] : Please refer to the user manual before any operation.

[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 RS15 user Manual
