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 k
g
per point (maximum).
• Before doing any installation or construction work, consult with an
installation expert.
•
W
hen 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.

eye bolts for suspension
For opt
imum safety, make sure to carefully follow the
precaut
ions below.
• Use only the supplied eye bolts.

• 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 stren
g
th
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.
W
hen 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
The horn directivity of the speaker is set at the factory so
that the upward spread is narrow and the downward
spread is wide.
1.
Remove all fixing screws on the grille, and remove the
grille from the speaker.
2.
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.
If you use the speaker as a floor monitor, change the horn
dispersion so that the upward spread is wide and the
downward spread is narrow, as shown in the diagram.
