NEXO 45N12Any Stage. Any Musician. One Monitor.

The revolutionary NEXO 45ºN12 brings all the benefits of line array
technology to stage monitoring. Incorporating a number ofgroundbreaking technologies, the 45ºN12 provides musicians,
contractors and rental companies with a single, scalable solution to
all their monitoring requirements

Alongside the obvious benefit of a ‘one box’ inventory, the 45ºN12 alsodelivers extraordinary directivity and consistency of coverage up to 2.5
metres back, plus very high level before feedback. And if you needmore SPL and wider coverage, just lock cabinets together to create‘monitor arrays’.

3NEXO 45ºN12 TechnologySay hello to the ‘smiling’ waveguide.
A serious advance in monitor technology.

Bringing the benefits of line array technology
to the stage.

The 45ºN12 incorporates an ingenious magnetic locking system, so
it’s easy to lock cabinets together to create monitor arrays wheremore SPL and wider coverage are needed.

and NXAMP 4x4 Powered Digital Controllers provide convenient andoptimised control and amplification for 45ºN12s in multiple
configurations (see pages 10/11).

As is the case with all NEXO systems, the 45ºN12 is controlled,powered and monitored by dedicated NEXO TDControllers. NXAMP 4x1

First, take a sphere. Then move the equator tothe 45 degree north parallel. Now, slice off thetop. This becomes the model for NEXO’s
revolutionary 45ºN12 Line Monitor. It also
explains the name.
With the point source located at the centre of4

the sphere, the waveguide radiates the high frequency at 45º. Unlike a
conventional waveguide in which the exit is rectangular the NEXO
monitor’s waveguide forms a smile. This takes into account the curvature
at the surface of the sphere. By creating a virtual acoustic source behindthe cabinet and beneath the stage, there’s no interference between
wavefronts when cabinets are locked together to form monitor arrays.

Locking magnets are located on the sides of the 45ºN12 cabinet.

Cabinets can be locked to form monitor arrays such as these stereo pairs –perfect for vocalists.

Directional and scalable,with very high headroom before feedback.

The only monitor you’ll ever need.Directional and scalable,with very high headroom before feedback.

CoverageHigh Frequency dispersion
is 30º horizontal, 22.5º
diagonal (coupling plane)
and 60º vertical(asymmetrical -45º / +15º).
Horizontal and diagonal
dispersion is scalable insteps of 30º and 22.5º
respectively when arrayed.
SPL and frequency
response are consistent up
to 2.5 metres back.

Because the coverage is so focussed, monitoring with the 45N12 often
results in lower acoustic power on stage, making it easier to achieve agood front of house mix. The compact, low-profile design is lessconspicuous than conventional monitors, making the 45ºN12 ideal for
live TV production, and the cabinet features a non-slip base with a skid
system and ergonomic handle for easy repositioning on stage.

Any stage. Any musician. NEXO 45ºN12 is the only monitor you need.

Time was when sound contractors and rental companies had to carrytruckloads of different monitors to be prepared for any eventually.
45ºN12 changes all that. Because cabinets can be locked together inmonitor arrays with no interference between wavefronts, the 45ºN12 is a

6flexible, one box solution for any stage monitoring application –delivering consistent SPL and frequency response within a tightlyfocussed area. Cabinets can even be locked back to back, allowing
musicians to face one another.

The NEXO TDController’s presets are precisely matched to the45ºN 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.
Internally mounted magnets allow 45ºN12 inter-cabinet
locking for coverage / SPL scalability.
