4. INSTALLATION PRECAUTIONS
TOA's lineup of line array speakers employs TOA's unique wave front control technology to create a sound
field that offers clear reproduction and uniform sound dispersion. This lineup includes versions offering either
5 degrees or 15 degrees of angled vertical directivity, as well as sub-woofer configured types. The use of
optional support brackets allows the line array speakers to be used in many applications as permanent sound
system installations.
• TOA's unique wave front control technology creates a uniform sound distribution field with interference-free
high frequency output, realizing high-clarity acoustic characteristics and long sound transmission
capabilities.
• The SR-C8LWP is a two-way speaker mounting a high-power 20 cm woofer and two compression drivers,
and featuring a 5 degree angle of vertical directivity and 110 degrees of horizontal. It is ideal for long
distance applications and can be powered by either one or two amplifiers.
• The SR-C8SWP is a two-way speaker mounting a high-power 20 cm woofer and two compression drivers,
and featuring a 15 degree angle of vertical directivity and 110 degrees of horizontal. It is ideal for shorter
distance applications and can be powered by either one or two amplifiers.
• By combining the long-distance SR-8LWP and short-distance SR-8SWP, a line array speaker system can be
built to support a variety of applications.
• The SR-C15BWP sub-woofer employs a large-diameter 38 cm woofer with high power handling capabilities,
and is designed to be used in conjunction with the SR-C8LWP or SR-C8SWP line array speakers.
• The line array speakers are designed to allow easy rear access for maintenance work.
• Overlap angles between individual speakers can be set in 1 degree units between 0 and 5 degrees when
constructing the line array speaker, making it possible to flexibly control speaker directivity.
• The line array speaker can be suspended with the additional use of the SR-RF8WP Rigging Frame.
The WP series is a splash-proof speaker, however please be sure to install it under a roof or eaves or in other
locations where the speaker is not directly exposed to rain or snow. Also, avoid installing the speaker in such
high-temperature and high-humidity locations as swimming pool facilities. Failure to follow these instructions
could lead to equipment malfunctions.

9. FLYING SYSTEMS USING THE SR-RF8WP RIGGING FRAME
9.1. Flying System Outline
Use the SR-RF8WP Rigging Frame for flying applications. Up to twelve line array speakers can be
simultaneously connected per frame, however the SR-C15BWP is calculated as two units.
Adjust the vertical directivity angle according to the installation environment. For applications that specify long-
distance sound transmission, link the long-distance SR-C8LWP speakers together.
Shown below is a basic flying system.
Rigging frame
SR-C15BWP
SR-C8LWP
SR-C8SWP
The line array speaker's vertical directivity angle is 5 degrees for the SR-C8LWP and 15 degrees for the SR-
C8SWP.
5 degrees 15 degrees
[SR-C8LWP] [SR-C8SWP]

Notes
• The speaker's splash-proof capabilities meet IPX4 requirements. However, always make sure that the
speaker is installed in locations (such as under a roof or eaves, etc.) not directly exposed to rain or
snow.
• Be sure to install the speaker so that its air hole is positioned downward. In this case, the brand mark
should be situated on the lower left corner of the speaker.
Ventilation slotVentilation slot
• Install each speaker so that the downward angle formed by its top panel is between 0 and 50 degrees.
Horizontal:

This flying system consists of four SR-C8LWP units, two SR-C8SWP units and one SR-C15BWP unit.
To enhance long-distance sound transmission capabilities, the four SR-C8LWPs are linked together at overlap
angles of four, two and one degree. As a result of this, the system's overall vertical directivity angle is 43
degrees.
Overlap angles can be set depending on how the speakers are linked together.
The horizontal directivity angle is 110 degrees.

As can be seen from the above figure, the overlap angle is equal to the rear opening angle between speakers.
Example: To adjust the sound radiation overlap angle to five degrees, set the rear opening angle between the
speakers to five degrees.
If the speakers are linked flat without no space between them, there will be no sound radiation
overlap. For overlap angle settings, refer to "Linkage Between Speakers" on page 17.

9.2. Assembling the SR-RF8WP Rigging Frame
Assemble the rigging frame referring to the figure below.
Ensure that fixing plates are correctly secured using two bolts (including plain and spring washers) supplied
with the rigging frame for each plate.
Since each fixing plate has its own installation position and orientation, refer to the figure for correct assembly.
Be sure that the forward mounting holes are always used in flying applications.

9.4. Connection Between Speakers
Inter-connect speaker sections referring to the figures below.
Ensure that both speakers are securely connected by tightening the supplied nuts and bolts from both left and
right sides.
Since connection holes for setting the overlap angle are provided at the back of the speaker, assemble using
the connection holes matching the required overlap angle. The overlap angle can be set within the range of 0
to 5 degrees in 1 degree units.

9.5. About the Flying Installations
Center of gravity
Anti-swing guy wire
• Use at least two points on both the left and right sides to suspend
the system vertically.
• Use the suspension points that allow the system to be set for a
desired downward angle. The downward angle increases as the
suspension points are moved rearward.
• Add an anti-swing guy wire as required. However, take care that
the speaker system's weight is not applied to the wire.
Cautions
• Suspension wires and shackles are not supplied with the speaker. Separately prepare and use those
which are strong enough to suspend the speaker system. Further, ensure that the ceiling structure from
which the speaker system is suspended is also robust and capable of supporting the system's total
weight.
• A total of up to 12 line array speakers can be connected per rigging frame. However, the SR-C15BWP is
calculated as two units. No more than a total of 12 units can be connected.
