Suspended Installation

CAUTION

●

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.

Yamaha cannot be held responsible for damage or injury

caused by insufﬁcient strength of the support structure

or improper installation.

■ Using eye bolts for suspension

For optimum safety, make sure to carefully follow the

precautions below.

CAUTION

●

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.

CAUTION

When using the eye bolts,

make sure that the

suspension angle is within

the range of 0 to 45

degrees, as shown below.

CAUTION

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

NOTE

so that the upward spread is narrow and the downward

spread is wide.

Remove all ﬁxing screws on the grille, and remove the

grille from the speaker.

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.

CAUTION

Be careful when rotating the horn so that you do not

accidentally cut the connection wires connected to the horn

driver.
