Neutrik Speakon NL4 plug wiring

Connect the plugs as shown below.
Be sure to use proper speaker cable – not
shielded instrument or line cable – for all
speaker connections.
The Speakon jack and barrier strip terminals are
connected in parallel.

Suspended Installation

●
The strength of the suspension points on the speaker is
60 kg
per point (maximum).
●
Before doing any installation or construction work, consult
with an installation expert.
●
When choosing the installation location, suspension wire and
mounting hardware, make sure all are strong enough to
support the weight of the speaker.
●
Some fittings may deteriorate over extended periods of time
due to wear and or corrosion. For optimum safety, the
installation should be checked thoroughly at regular intervals.
■
Using eye bolts for suspension
For optimum safety, make sure to carefully follow the
precautions below.
●
Use only the supplied eye bolts.
●
Use three or more eye bolts for suspended installations.
●
Use the optional array frame if you intend to suspend a
speaker from another suspended speaker.
●
Install the eye bolts to multiple surfaces of the speaker, not
just one surface.
■
Eye bolt strength
Keep in mind that the strength of the eye bolt differs
depending on the suspension angle of the speaker. Make
sure that the load for each eye bolt is less than 740 kg
when suspending at an angle of 0 degrees, and less than
185 kg at an angle of 45 degrees.
When using the eye bolts, make sure that the suspension angle
is within the range of 0 to 45 degrees, as shown below.
Do not suspend the eye bolts as shown in the diagram below.

Rotatable horn

1.

Remove all fixing screws on the grille, and remove the

Remove all screws installed on the horn, pull out the
horn from the speaker, rotate the horn 90 degrees,
and re-install the horn to the speaker.
Be careful when rotating the horn so that you do not
accidentally cut the connection wires connected to the horn
driver.
