8.1. Speaker Outputs
The PLM+ is available with either 4 mm binding posts or Neutrik speakON connectors for the outputs.
The outputs of the PLM+ can produce a high voltage. Do not connect or disconnect loudspeaker/s while the
PLM+ is powered on. Never operate the PLM+ with any portion of bare loudspeaker wire exposed.
For speakON connector versions, do not use mating plugs without the rear covers in place.
8.1.1. Bridge Mode
NOTE: When Bridge Mode is activated, CLASS 3 wiring is required.
Power outputs may be bridged on PLM 12K44 and 20K44 models by following the configuration instruction in the
Lake Controller Operation Manual (I/O CONFIG > OUTPUT CONFIGURATION) and the wiring instructions in this chapter.
Bridge Mode can only be activated/deactivated using the Lake Controller software.
