SYSTEM OPERATION
Electronic Controller The NEXO NXAMP presets are precisely matched to the LS series cabinets and include sophisticated
protection algorithms. Using LS Series cabinets without a properly connected NXAMP will result in poor
quality and can damage components
Speaker Cables LS18 is wired 1- & 1+ on 2 In/Out Speakon connectors
Single cables can thus be used to loop through to PS15-R2 or to Geo S12.

[a] Response curves & data : Half-Space Anechoïc radiation for the LS18 + NXAMP.
[b] Sensitivity & Peak SPL data : these will depend on spectral distribution and crest factor of program material. Measured with band limited Pink Noise., 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.
