Back Panel Interface; Speaker Outputs - Lab.gruppen PLM series Operation Manual

8. Back Panel Interface

An overview of the back panel interface is provided in section 4.2. This chapter describes each cluster of
connections as shown in Figure 8-1.
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.
On Speakon versions, do not use mating plugs without the rear covers in place.
The PLM is capable of bridge-mode operation,
however currently the system management
software does not support this mode and it is
therefore NOT recommended.
Please contact plmsupport@labgruppen.com for further information on bridge-mode operation.
8.1.1 Speakon Connectors
Figure 8-1 shows a two-channel PLM 14000 with Speakon connections. Speakon connections are also
available on the four-channel PLM 10000Q and PLM 20000Q. Sections 8.1.1.1 and 8.1.1.2 describe the
wiring, pin-out and output configuration for the two- and four-channel models respectively.
8.1.1.1 Two-channel PLM Speakon Connections
Two-channel models provide both power output channels simultaneously on two 4-pole Speakon connec-
tors. Both connectors carry both channels; the second connector offers the channels in reverse order.
