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. [SR-C8LWP] [SR-C8SWP] 5 degrees 15 degrees... - Page 13 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.
- Page 14 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.

Page 15: Assembling The Sr-Rf8Wp Rigging Frame
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. -
Page 16: Connecting The Rigging Frame To The Speaker
Connect the rigging frame to the speaker referring to the figures below. Confirm the positioning of the horn (SR-C8LWP and SR-C8SWP only), then correctly mount the rigging frame to the speaker by tightening the supplied nuts and bolts from both left and right sides. -

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. -
Page 18: About The Flying Installations
9.5. About the Flying Installations 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. -
