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
Power outputs may be bridged on all PLM+ models by following the configuration instructions 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.
Note: When Bridge Mode is activated, CLASS 3 wiring is required.
