WIRING NEUTRIK TYPE CONNECTORS
The diagrams below show how connections are made to a Neutrik Speakon
TM
style loudspeaker connector.
Terminations may be soldered, or made by means of their built-in screw and pressure clamp. If using the
pressure clamp, it’s important to tighten it fully, then to wait about ten minutes (longer is better), then to
tighten it again. This is because copper wire
flows
under pressure. After initially tightening the screw
clamp, some minutes later the screw will no longer be as tight due to the effect of the compression on the
copper. Typically, only one cycle of “tighten – wait – re-tighten” is required for a secure connection.

DANGER:
When wiring the amplifier(s) to the loudspeaker(s), always power-down the
amplifier(s) and disconnect their AC Mains plug(s). Many modern, high power amplifiers
can deliver enough voltage and current to cause a harmful or lethal electric shock. Shocks
from very low frequencies, such as kick drums, can cause the human heart to stop beating
at relatively low power levels.
WARNING:
After wiring the amplifier(s) to the loudspeaker(s), first power up all devices
that are upstream of the amplifier, such as mixers, equalizers, compressor/limiters, etc.,
before
powering-up the amplifier. This is to avoid passing any clicks or pops that may
originate in the upstream devices to the loudspeakers. The amplifier should initially be
powered-up with its gain controls turned all the way down. After making sure that a
continuous signal is present, such as a CD playing, slowly raise the level of the gain
controls to establish that the wiring has been installed correctly. Only then should the
loudspeaker be operated at normal output levels.
The VLF208 and VLF212I have one (1) NL4-compatible locking connector. The VLF212P has two (2) NL4-
compatible locking connectors.
