45N-12 Stage Monitor Preliminary Data Sheet
Key Features
• World’s first line monitor.
• Can be joined together into arrays to provide a
scalable solution for wider coverage and higher
SPLs.
• Very high headroom before feedback.
• Focusses coverage only where needed for lower
acoustic power on stage.
• Discreet, low profile design.
• Ingenious magnetic locking system.
• Non-slip base with skid system and ergonomic
handle for easy repositioning on stage.
Waveguide forms a ‘smile’ to eliminate wavefront
interference when monitor is arrayed.
Ingenious magnetic locking system joins multiple
cabinets into arrays.
The revolutionary NEXO 45N-12 is the world’s
first line monitor, bringing all the benefits of line
array technology to the stage.
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 with no interference
between wavefronts. Now there’s a single monitor
reference covering the needs of all musicians,
scalable for wider coverage and higher SPLs.
The 45N-12 delivers very high headroom before
feedback, and focusses coverage only where it’s
needed, resulting 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 to form arrays. The compact, low
profile design is less conspicuous than conventional
monitors (ideal for live TV production), and the 45N-
12 features a non-slip base with a skid system and
ergonomic handle for easy repositioning on stage.
System Applications
• Touring or fixed live sound applications.
• Live television production.
• Single monitor reference covering the needs of all
musicians.

SYSTEM OPERATIONS
Electronic Controller
The NEXO TDcontroller’s 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.
LIMITED WARRANTY
NEXO loudspeakers and electronics are covered against defects in workmanship or materials for a period of two (2) years from the original date of
purchase. At the option of NEXO the defective item will be repaired/replaced with no charge for materials/labour. The item is to be adequately
packaged and dispatched, pre-paid, to a NEXO authorised distributor/service centre. Unauthorised repair shall void the warranty. The NEXO

[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.
