Nexo 45N-12 Line Monitor

NEXO's 45N-12 represents a true innovation in stage monitoring.

As a completely arrayable solution, the 45N-12 delivers a tight and focused beam of sound utilising NEXO's new monitor waveguide system.

Unlike conventional high frequency waveguides which are rectangular, the NEXO monitor waveguide has a curved "smile" enabling cabinets to be linked together to form arrays with no interference between wavefronts. For the first time, there is a completely scalable stage monitor designed to address the needs of all musicians.

The 45N-12 delivers extremely high headroom before feedback, and focuses coverage only where it's needed, resulting in lower acoustic power on stage. SPL and frequency response is consistent for up to 2.5 metres back.

The ingenious magnetic locking system joins multiple monitors together to form arrays instantly. The compact, low profile design is less conspicuous than conventional monitors making it perfect for stages and live television production alike. With a non-slip base, skid system and ergonomic handle, the 45N-12 is designed for fast and easy manoeuvrability on stage.

[a] Response curves & data : Half-Space Far Field for the 45N-12 + NXTD.

[b] Sensitivity & Peak SPL data : these will depend on spectral distribution and crest factor of program material. Measured with band limited Pink Noise. Nominal refers to Voice Decade (300Hz - 3kHz), Wideband to the specified ±3dB range. Data are for speaker + processor + recommended amplifier combinations. Peak SPL is at clipping of recommended amplifier.

[c] Directivity curves & data : obtained by computer treatment on off axis response curves.

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.
