LE100/LE200

CONNECTIONS

LE Series monitors are fitted with low-profile, NL4-type four-pin push-lock connectors, rated
at 30 A. All the connectors (five on the LE100, four on the LE200) are wired in parallel: use
whichever connector(s) suit the stage cabling layout. The multiple connectors permit simple
interconnection between monitors on the same circuit; they can be used to "daisy-chain" the
amplifier output to the next speaker.
Important: please ensure that the total impedance of multiple LE Series monitors connected in
this way is not less than the minimum load impedance the amplifier channel can drive:
Wire the mating connectors according to the following pinout table:
Note that as pins 2+ and 2- are unused on the LE100, standard four-core speaker cables
terminated in NL4s may be used without a problem. However, note that all four pins on each
connector - including those that are unused by the speaker itself - are wired in parallel to all
other connectors on the cabinet.
