7.11.8.1. Configure # of Cabinets in Parallel
This option allows selection of the number of speaker cabinets connected to each PLM+ output channel. Select
individual or multiple outputs and use the rotary encoder to set the value from 1 to 4. This value is used by
LoadSmart to conrm the correct connection and status of the speakers connected to each PLM+ channel.
7.11.8.2. LoadSmart Verification
Select this option to initiate LoadSmart verication, then select YES to continue. LoadSmart performs a rapid test
of all output channels, and displays the results on the LCD a few seconds later.
Figure 7.23: LoadSmart Verication Results Screen
The Load Results page provides three items of information per output channel:
• Conrmation that the speaker connected matches the speaker ngerprint assigned to the channel. If no
Fingerprint is assigned, NO MODEL will be displayed. If the wrong speaker is connected; “Wrong Speaker”
will be displayed
• Result of speaker cabinet count; this will either be OK or WRONG.
• Estimated number of speakers connected to the channel.

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.
