NEXO UNVEILS 45°N-12 LINE MONITOR

9月 2010 |

The revolutionary NEXO 45°N-12 wedge monitor brings all the benefits of line-array technology to the stage. It draws on NEXO’s patented Hyperbolic Reflective Wavesource which is used throughout the GEO range of high-performance loudspeakers. The design works by wavesourcing, creating virtual acoustic sources behind the enclosure itself and below the stage, using reflection rather than coercion to determine the shape of the wavefront. Unlike a conventional high frequency waveguide in which the exit is rectangular, the NEXO monitor’s waveguide forms a ‘smile’, enabling cabinets to be linked together to form arrays without interference between wavefronts.

Monitor engineers will find that the N-12 design produces a very sharply defined dispersion pattern at the same time as offering a huge improvement in terms of level before feedback. The focused coverage results in lower acoustic power on stage. SPL and frequency response are consistent up to 2.5 metres back.

An ingenious magnetic locking system joins multiple monitors together, allowing scalability for both coverage and SPL level. The compact, low-profile design is less conspicuous than conventional monitors (ideal for live TV production), and the 45°N- 12 features a non-slip base with a skid system and ergonomic handle for easy repositioning on stage.

SYSTEM OPERATIONS

Electronic Controller The NEXO TDcontrollers presets are precisely matched to the 45N Series cabinets and include

sophisticated protection. Using 45N Series cabinets without a properly connected NEXO

TDcontroller will result in poor sound quality and can damage components.

Dispersion configuration Internally mounted magnets allow 45N-12 inter-cabinet locking for coverage / SPL scalability

Sub-bass LS600 extends system low frequency response down to 38 Hz

Speaker Cabling Active: 1-/1+:LF; 2-/2+: HF

Passive: 1-/1+: Not Connected; 2-/2+:LF + HF
