2. GENERAL DESCRIPTION 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. 3.

6. BI-AMPLIFIER AND SINGLE-AMPLIFIER OPERATIONS The SR-C8 series speakers are supplied from the factory set up for bi-amplifier operation. However, this default specification can be switched to single-amplifier operation mode by simply changing the position of an internal connector. (Refer to page 9. "Switching to Single-Amplifier Operation Mode.") 6.1. Bi-Amplifier Operation 6.1.1.

7. SWITCHING TO SINGLE-AMPLIFIER OPERATION MODE To switch the speaker's bi-amplifier operation mode to single-amplifier operation, remove the speaker's rear input panel and change the speaker's internal wiring. Switching Power Modes Step 1. Remove the four screws securing the input terminal panel and pull out the panel. Step 2. Pull out a short length of the wiring connected to the back side of the input panel. Step 3.

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 longdistance sound transmission, link the long-distance SR-C8LWP speakers together. Shown below is a basic flying system.
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.
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.
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.
9.3. 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. When suspending the SR-C15BWP sub-woofer, be sure to mount it in the uppermost position (i.e. immediately below the rigging frame).
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 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.
