[SR-C8L] [SR-C8S] 5 degrees 15 degrees... - Page 14 This flying system consists of four SR-C8L units, two SR-C8S units and one SR-C15B unit. To enhance long- distance sound transmission capabilities, the four SR-C8Ls 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-Rf8 Rigging Frame
9.2. Assembling the SR-RF8 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-C8L and SR-C8S only), then correctly mount the rigging frame to the speaker by tightening the supplied nuts and bolts from both left and right sides. -
Page 17: Connection Between Speakers
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. -
Page 19: Installing The Flying System Using The Sr-Cl8 Cluster Bracket
10. INSTALLING THE FLYING SYSTEM USING THE SR-CL8 CLUSTER BRACKET 10.1. Flying System Outline This flying system uses the SR-CL8 Cluster Bracket. Using the cluster bracket, up to four speakers can be connected to each other when suspending in vertical or horizontal orientation. Note that the sub-woofer cannot be installed using the cluster bracket. - Page 20 10.2.2. Vertical flying installation Cautions • Wires and shackles to be used for suspension 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 standing the system's total weight.

Page 21: Horizontal Flying
• Add an anti-swing guy wire as required. However, take care that the speaker's weight is not applied to the wire. Anti-swing guy wire 10.3. Horizontal Flying 10.3.1. Cluster bracket attachment Attach the cluster brackets to the leftmost and rightmost of the connected speakers referring to the figure below. - Page 22 10.3.2. Horizontal Flying Installation Cautions • Wires and shackles to be used for suspension 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 standing the system's total weight.

Page 23: Speaker Stacking
It is possible to stack the line array speakers using the SR-RF8 Rigging Frame. Up to eight speakers can be stacked, noting that each line array speaker is calculated as 1 unit and each SR-C15B sub-woofer as 2 units. Shown below is a basic stack system. Note that casters must be prepared separately. SR-C8L SR-C15B Rigging support bracket... -
Page 24: Assembling The Sr-Rf8 Rigging Frame
11.2. Assembling the SR-RF8 Rigging Frame Before assembly, first determine whether to set the mounting position of the fixing plate at the center or forward, taking the stack system's center of gravity into consideration. Ensure that fixing plates are correctly secured using two bolts (including plain and spring washers) supplied with the rigging frame for each plate. -
Page 25: Connecting The Rigging Frame To The Speaker
11.3. Connecting the Rigging Frame to the Speaker Connect the rigging frame to the speaker referring to the following figure. Correctly connect both units by tightening the supplied nuts and bolts from both the left and right sides. When using the SR-C15B sub-woofer in the stack system, mount it in the lowermost position (i.e. immediately above the rigging frame). -
Page 26: About Stacking
11.5. About Stacking • Separately prepare casters and mounting hardware, which function as the rigging frame's feet. • When stacked, the overhang of the front or rear portion of the line array speaker cannot extend more than 10 cm beyond the edge of the rigging frame. Notes •... -
Page 27: Using The Sr-Sb8 Rigging Support Bracket
12. USING THE SR-SB8 RIGGING SUPPORT BRACKET The SR-SB8 Rigging Support Bracket is used to prevent the stacked SR-C8 series line array speakers from tipping over. Be sure the SR-SB8 is used whenever six or more SR-C8 series speakers are stacked. Count the SR-C15B sub-woofer as two units when configuring a system. -
