Recommended Amplifiers
2 amplifier channels for directional mode
operation, each rated at 1000 to 2000 Watts
into 8Ω per channel
or 1 amplifier channel for omni mode
operation, rated at 2000 to 4000 Watts into
4Ω
2 amplifier channels for directional mode
operation, each rated at 1000 to 2000
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
The RS18 must use separate cables to the main system
Accessories
Bumper – Flying Plates – Dolly - Front Wheel Board
Rigging system [d]
Please refer to the user manual before any operation
SHIPPING & ORDERING
Packaging
RS18s are packaged individually.
Order RS18-C (finished grey carpeting) or RS18-P (finished in black structured coating)

[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.
