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.

 

[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
