Connections

The SR-18 has barrier strip screw terminals that accept up to #10 AWG stranded loudspeaker wire.

Input- Connect the amplifier’s output signal to the loudspeaker’s INPUT terminals. Observe proper polarity. Use the largest wire size and shortest length for the application.

Output- The SR-18 has two terminals marked OUTPUT. These terminals are connected in parallel to the INPUT terminals and can be used for con- necting multiple SR-18 enclosures in parallel with one another. Connect the OUTPUT terminals to the next loudspeaker’s INPUT terminals. Observe proper polarity of connections.

Warnings and Important Notes

NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance.

NOTE! Ensure that the amplifier driving the parallel loudspeakers is rated to drive the lower impedance (Example: 4 enclo- sures in parallel will yield 2 ohms impedance, nominally).

Use QSC’s Quick Mount bracket for wall mounting or U-bracket for wall mounting. Enclosure is not designed to be sus- pended, flown, or rigged by any other method. Do not suspend, fly, or rig this enclosure.

Always keep sound pressure levels in the listening area below levels that can damage human hearing.

Install in accordance with QSC Audio Product’s instructions and a licensed, professional engineer. Only use attachments, mounts, accessories, or brackets specified by QSC Audio Products, Inc. Refer all servicing to qualified personnel. Servicing is required when the apparatus has been damaged in any way.

WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabi- nets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed or non-load rated com- ponent could significantly reduce the strength of the installation, placement, or array. Any such condition severely reduces the safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading condi- tions of the installation and any possible short-term unexpected overloading. Never exceed the rating of the hardware or equipment. Consult a licensed, professional engineer when any doubt or questions arise regarding a physical equipment installation.
