NEXO's 45°N 12 is their first 45°N dedicated monitor which brings all the benefits of line array technology to the stage.  The 45°N 12 delivers very high headroom before feedback, and focuses coverage where it's needed, resulting in lower acoustic power on stage.  SPL and frequency response is consistent up to 2.5 meters back.

A magnetic locking system joins multiple monitors together to form arrays.  The 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 Specifications 45N-12 with NX TD Controller:

  • Frequency Response [a]: 55Hz - 19kHz ±3dB.
  • Usable Range @-6dB [a]: 50Hz - 20kHz.
  • Sensitivity 1W @ 1m [b]: 106dB SPL Nominal / 104dB SPL Wideband.
  • Nominal Peak SPL @ 1m [b]: 1 unit: 137 to 140dB Peak / 2 units: 140 to 143dB Peak.
  • HF Dispersion [c]:
    30° Horizontal - Scalable 30° steps when arrayed.
    22.5° Diagonal (Coupling Plane) - Scalable 22.5° steps when arrayed.
    60° Vertical (Asymmetrical -45° / +15°).
  • Crossover Frequencies LF-HF: 1kHz Active or Passive (internally configurable).
  • Nominal Impedance Active LF 8 ohm, HF 16 ohm. Passive 8 ohm.
  • Recommended Amplifiers Active LF 1000 to 1500 W 8 ohm / HF 250 to 500 W 16 ohm. Passive 1200 to 2000 W 8 ohm.

[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 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
