CONNECTIONS
XE Series monitors are fitted with low-profile, NL4-type four-pin push-lock connectors, rated at
30 A. All the connectors are wired in parallel: use whichever suit the stage cabling layout. The
provision of multiple connectors permits simple interconnection between monitors on the same
circuit; they can be used to “daisy-chain” the amplifier output to further speakers. However,
note that all four pins on each connector - including any that are unused by the speaker itself -
are wired in parallel (pin-to-pin) to all the other connectors on the cabinet.

Important: Each iK42 amplifier channel can drive a maximum of two XE Series monitors in
parallel. Do not attempt to connect more than two monitors to any one amplifier channel as the
combined load impedance will be lower than the minimum impedance the amplifier is designed
to drive. This will result in unsatisfactory performance and may cause damage to the amplifier.
Wire the mating connectors according to the following pinout table:
Pin XE300 XE500
Passive x-over Bi-amped Bi-amped only
1+ Input ‘+’ LF input ‘+’ LF input ‘+’
1- Input ‘-‘ LF input ‘-‘ LF input ‘-‘
2+ (no connection) HF input ‘+’ HF input ‘+’
2- (no connection) HF input ‘-‘ HF input ‘-‘
The speaker output connectors on the iK42 amplifier are also NL4 type (Neutrik Speakon™).
The connectors for amplifier Channels 1 and 3 also carry the outputs of Channels 1 and 4, so
that when the amplifier channels are configured in pairs for bi-amp operation, standard four-core
speaker cables terminated in NL4s may be used throughout the system without a problem.
