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.
