Select the DISCRETE mode or the PARALLEL mode.

 

Do not change the DISCRETE / PARALLEL setting while the 
speaker is in use.

 

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.

 

●

 

The strength of the suspension points on the speaker is 

 

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.

 

■ 

 

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.

 

■ 

 

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.
